My Omnia 7 keeps loosing it's 3G connection

My Omnia 7 keeps loosing it's 3G connection. To restore it I have to restart the phone. T-Mobile say that this happens from time to time, but it's happening every day now. It's annoying as it stops my push email from being up to date, and of course prevents the use of any internet based services until the phone is restarted.
Has anyone else noticed their phone has switching to GSM?

Had mine for 6 days.Been fine up until today,then I had the same problem.Only the once so far.

Confirm loosing 3G
Confirm loosing 3G connection, and also have phone call failures.
Factory reset did not solve the problem.
Bring it back to shop
Blackstone is back now!

At first this was occasional with my phone, then more frequent, and it's all the time. If I want to use the Internet I have to restart the phone. My house is covered by full HSPA, but the only way to get it is to take the battery out while the phone is switched on. I can sometimes get 3G by a simple restart, which I lasts about 40 minutes.
I like the phone, so I'm going to hold out for a software update. All it needs to do is check available networks and I think that, if this is a wide spread issue, Samsung/Microsoft will fix it. Hope so.
Please post here if you have this issue too.

I have also been having this issue... sometimes it doesnt come back straight away when i restart it but after about 10mins its back.
When I activated it with orange I was told to expect a few txt msg's that would need deleting and the phone restarting... I only got 1 msg, maybe this has something to do with it, maybe the phone hasnt been sent enough updates.

I also have this issue and have done for weeks. Orange couldn't solve it either.
It only happens overnight at home. I either need to reset the phone / rescan available networks or turn flight mode off and on again for the connection to restore.
I was thinking it may be an issue with t-mobile since it only happens at my home where orange signal is poor and i roam over to t-mobile.
If i stay in an area with good Orange signal i don't get the problem.
Good to know i'm not the only one with this problem. It's very annoying!

Hi y'all.
I had the same problem: 3G was lost every time. I was fed up restarting the phone every time, so I looked for another way to get 3G back. I found out that disabling and enabling SIM security (phone > setttings) got me 3G again... for a short while.
But: after disabling SIM security permanently, 3G kept on going (in fact for over a week now).
I think that changing the PIN to some other number, might cause this. I haven't yet tried changing it to the default PIN again, to see if using that for SIM security solves it. For the moment I'm too happy it works again.

I have suffered from poor reception issues ever since I got my Omnia 7.
It seems like the reception comes and goes. I will receive e-mails, which proves that the phone has been connected, but as soon as I try to use data myself, by visiting a web page or refreshing an app like facebook, the reception disappears and the "no reception" symbol drops down from the status bar.
Also, often when I try to send an SMS, it will appear to have been sent, yet 10 minutes later I will receive a "Can't send...try again" message. Once I have received this, the SMS will never successfully send. However, in the meantime I can receive SMS messages, which shows that the phone has been getting a signal.
This is SO frustrating and is ruining my experience with the phone.
I have posted requests on the Microsoft Answers forum and the only suggestions have been to reset the phone or turn WiFi off. Neither of these have had any effect. I have never enabled SIM lock.
I have heard that there is a firmware update due soon which includes a new radio stack. I am desperately hoping that this will improve the situation, as at the moment I cannot rely on my Omnia 7 as my only phone.
Alex.

Hi Loco,
You are right in saying that social answers doesn't really help much .
Luckily there IS a new firmware from a couple of days ago! Check out the Omnia 7 Dev section. There are only a few posts.
And here is also a good link for you. You are right to assume that it comes with a new radio stack which improves on performance.

Finally found a thread on this... I have been having a similar problem since I got my phone from Optus here in Australia. I took it back and they replaced it for me but the new phone is exactly the same. I don't lose the 3G icon but anything data related just ceases from loading. Right now I'm trying to refresh the Facebook app and it just comes up with 'Unable to connect', even though I have full 3G reception.
I flashed it to the newer leaked firmware and it hasn't changed anything, problem still persists unfortunately. This is a major problem that isn't getting enough attention! It seems quite widespread and Omnia 7 specific.

Had similar problems, but after I changed my provider ( O2-Germany), 3G is stable.

For the people having this problem, have you tried setting the phone to prefer 3g? Details of how to do this are here http://forum.xda-developers.com/showthread.php?t=915813

Same here man. On Optus and my reception sucks with this device. What the hell is samsung doing? FIX IT!

I have been having this problem with my Omnia 7. The frustrating thing is this is a replacement phone I had for an LG which I had replaced THREE TIMES due to random resets. So now I have a phone that I have to turn off and on EVERY MORNING in order for the data connection to start working again. Needless to say I am very frustrated. I am on Orange in the UK. I suspect it could be related to when being an a poor reception area and it tries to switch to tmobile. I am going to try turning roaming off. Please, if anyone finds a solution to this let me know.
Thanks

My problem got worse with the Mango update. I'm now on my 2nd handset after having a replacement from Orange warranty. This one still loses it's connection but much less frequently.
TBH i don't think it will ever get fixed. I started an MS Answers thread months ago and lots of people had the same problem but we never got a response from MS.
Conisdering the age of the model now I doubt Samsung care, well they didn't seem to care a year ago so they won't now... For this reason I will not buy another Samsung phone. It's infuriating.

Looks like I am stuck with it until December then when I can upgrade to a Nokia lumia. A long wait :-(

i have this issue, too.. but for me i only have to set airplane mode on and off. sometimes i deactivate data connection, go to a random website, get the 'no connection' error, then activate data connection back and it works.
however, after installing the latest drivers & firmware, i get this issue A LOT less frequent. like once in 2-3 days.
i hope ms or samsung will fix this because it can get really annoying. especially when you need eg. a quick google-search..

Just flicking the flight mode wouldn't be so bad but that doesn't work for me, I have to restart the phone each time. I love WP7 but this and the other problems with the LG is driving me nuts. Almost wondering whether I should have just followed the crowd and gone for an iPhone.

Same as me - Flicking flight mode on-off doesn't solve it, needs a soft-reset.
Like I say, there are quite a few with Omnias on Orange with this problem.
I'm in the same boat, I've had this for months now so I guess I'll just deal with it until I can upgrade the start of April and get a Lumia (hopefully the EU 900/910 will be here by then!). There is no way on this earth Samsung are getting any more of my money. Nokia seem fully commited so they can take my cash next time!

I have the same problem with the data stopping working on o2 in the UK. But I also sometimes cant receive calls even though the phone has service, then there are the times where it site there going GPRS/3G/3G+/No Service and you cant do anything with it apart from pull the battery.

Sudden Loss of Data on Nexus S

Hey guys,
This is actually my first post here but I do A LOT of reading on this forum.
I didn't quite find anything regarding my question (or at least a solid answer), however, so I've decided to post it up.
Has anyone else experienced a sudden loss of data from time to time out of nowhere?
I go from having Full Green 3G bars to grey bars out of the blue. I've heard the green bars is to let you know that you are connected to Google services but I am not able to access anything that uses data.
For instance, when I open up the browser, I receive an error telling me there is no network connection. When I open up anything else that uses a data connection, Market, News, etc, I receive the same error about there not being a connection.
This would make sense if I was moving and going in and out of service areas, but it happens when the phone is simply sitting on my desk and not moving at all. I usually use it to listen to Pandora while at work and have noticed that the songs cut in and out due to this sudden loss of a data connection.
I went from a Nexus One to the Nexus S and have never, not once, lost my full 3G bars in this same exact location. I personally believe its a software bug of some kind and have high hopes for it being fixed in the future. The N1 had similar issues when it first launched and Google / T-Mo were able to remedy that for the most part.
I am actually on my third Nexus S because the first two had some type of hardware issue; the first one's back button didn't work or light up and the second one had a blown ear speaker and would sound like a blown speaker in a car. As an early adopter, I expected this, so it didn't bother me in the least bit.
ALL of them did the same thing, so I know it is not just limited to my exact phone. This is definitely something with the Nexus S in general (or the current build of Gingerbread).
Can anyone shine some light on this situation? Thanks in advance and keep up the great work here guys!
---------------------------------------------------------------
UPDATE: Here are a few steps that I have taken in order to solve my sudden loss of data issue. I'm not guaranteeing this will work for you, but it has worked for me and a couple of users here on the forum.
Do the following:
Activate / Use the Sim Card that came with the phone (this is to ensure you are using the latest sim cards)
Make sure you have a 4G internet plan. (No t-zones, No web2go -- FULL internet only)
Call T-Mobile and have ask them to Reset your phone with their Towers
Here's a more technical explanation posted by Johoja:
1) Having network selection set to manual ( i.e selecting 302490 or TMOBILE) will result in No Service on a reboot. Solutions: - Have to cycle airplane mode to get it to pick up service (can be done with automatically tasker) - OR Use automatic network selection. (you can force wcdma only but that will reset the SMSC which is annoying if you go in and out of wind away/home areas and you want to roam.)
2) Being in a area with no service for extended periods of time 5+minutes(subway, basement, etc) will result in a dead baseband, meaning once you come into an area with service the phone will not reacquire signal, airplane mode will not work as the baseband is now crashed, cant maunally search for a network. Have to reboot to get signal. Solutions: -Use tasker to cycle airplane mode on and off when in no service areas i.e) search signal 4 minutes, airplane mode on 10 minutes. This will keep the baseband from crashing and possibly save battery. -Use NoBars to accomplish thesamething ( taskergivesyou a bitmore flexibilty of course but harder to use) http://www.appbrain.com/app/nobars-b...omdryer.nobars - Use airplane edit to avoid turning wifi/bt off when airplane mode is on. http://www.appbrain.com/app/airplane...kalti.airplane
3) WCDMA perferred does not work. - No solution
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=747f398a6c1bb2b9&hl=en&start=40:

I read one users response on a different thread regarding something similar to the issue that I am having.
They said T-Mobile told them to get a newer sim card and that this may remedy the problem. In my case, this has been the only constant in the 3 phones that I have been through. I have had the same sim card for about 3 years or so now.
I will try activating the sim card that came in the box with T-Mo to see if this remedies the problem. Since I'm at work right now I will have to try when I get home later.
Does anyone think this will have any affect what-so-ever?

The galaxy s phones when first released, all variants, had issues of signal dropping from full to zero bars while sitting in one place. I remember because there were YouTube videos of it All over and it was shortly after the apple antenna issue.
Not sure if or how it was ever resolved. But it seems that Samsung may just have this type of radio baseband performance if we see all these individual units doing this. I don't know maybe others can respond.

I have the same issue as the OP. I travel to the same location weekly with NEXUS ONE, signal never drops in the T-MO Country here locally, and streaming CNET POD CAST never a hiccup, however, with the new NEXUS S, I would lose DATA Connection only, while the 3G will show full signal. I had to reboot the phone to get the DATA back.
is it the S issue or 2.3 issue?
food for though....

If you have T-zones or Web2go or Phones 1st web, you will have problems

I had the same problem too, now I fixed the problem. The thing was that had the wrong data plan on the NS, i had my old web plan from my hd2 which seems like different from the one for the NS. I restarted my phone after 5 mins off and now i have my internet working beautifly. A T-Mobile rep said that it was an error in the system that made the phone think that that was the right plan for the NS for a few. A glitch you may say, but all you have to do is put the right data plan that all, easy. Hope this helped and have a wonderful holidays everyone.

this is happening to me too, last night for a little while and today for about hte last 4 hours can't get connection back. i have full white bars, with 3g icon but can't access anything

So I activated the new sim card last night and I'm still having the same problem. Albeit it doesn't happen as frequent, but it still does it nonetheless.
I will call T-mo again to verify my plan. I am on a 1500 Minute Family Plan which includes unlimited data and messages. I will see if they need to tweak something and let you guys know if this remedies the problem.

Ok, it seems like the issue has been resolved after I spoke to T-Mobile earlier today.
The rep on the phone verified that the data plan I was on was in fact the correct one. He said he was going to reset the signal from the towers to my phone to see if this would resolve the issue. He asked me to turn my phone off for about 15 seconds after we hung up.
Since then, I haven't seen the problem arise again so my guess is that it somehow fixed whatever was going on.
I'll let you guys know if this changes and the problem occurs again.

What's with the CAPS? ?
On topic: i have a captivate and I can confirm that all galaxy S phones had droppend data. An official ota update fixes it so maybe you guys need to wait for something official. Isn't there a new firmware for the nexus S already? Try flashing that and see if you still have issues.

Doesn't every android phone from samsung have this problem?
I know the Moment has that problem, after 3 updates samsung called it quits, I still have to reboot mine 2 to 3 times a day for data lockups.

@timur525 Yea, I'm already on 2.3.1.
I manually updated the first hour it came out hoping that it would solve the issue. The problem was still there after the update.

I have exactly the same issue as the OP. Extremely annoying to reboot the phone every time it happens. One thing I have noticed is that my phone doesn't know its number. If I go to settings, about phone, the number says unknown.

That shouldn't affect anything. My number shows up in status.
I had this issue resolved a few months ago as the push-to-talk app Tikl requires this in order to use it.
I was having the problem even with my number showing up. Call T-Mobile and have them reset you with the towers like they did for me and see if that helps you too.

I posted about this same issue on wrong section of the forum. Ive had this issue ever since samsung vibrant. I have applanet installed on my phone and some of the app that i installed accessed my apn and totally changed my apn setting to "Sirious application disabled.epc.tmobile" or something like that so i wyped everthing off from the phone and so far i havent had the issue ever since yesterday. Also i had the locale and language setting to korean so im thinking that might be causing it also.

That's what I remember too. I think its just an issue with the radio Samsung uses in all their phones. Might not be a way to fix it if even their new phones like the nexus s still have this issue. They prob would have tweakdd it by now if they could.

Same problem here. Xmas eve on shift and I have a phone that had no connection whatsoever (not even phone capabilities) this may be the one thing that takes the phone back. (If it happens again)

Have you called T-Mobile to see if they can give you a reset to the towers?
I had this done yesterday afternoon and haven't had the problem again since.
Also, if you'really using an old sim, I would suggest activating the one the phone came with just to be on the safe side.
If that doesn't help you then I would at least wait until just before your return period ends to see if there will be an update to address the issue.

Samsung Tab A (SM-T285) Wifi constantly disconnecting-reconnecting

Hello Guys, I'm not sure if this is the right forum to ask something like this, so apologies if I'm asking in the wrong place, but I've searched a lot the past days and haven't found a solution yet :/
Less than a week ago, I bought a Samsung Galaxy Tab A6 (SM-T285) 7" LTE, and pretty much since day one, the tablet keeps disconnecting and reconnecting on every wi-fi I tried so far (3-4 different networks). I lose my connection for a couple seconds, causing any app running to lag a bit, then the notification that I have been connected to (the same) wi-fi comes up, and it starts working again. I googled a bit and tried using WPS button, Keep Wifi on during sleep, always allow scanning, even turned flight mode on, but the problem remains. Also, googling usually returned solutions that were aimed towards the router, although I'm pretty sure it's something to do with the tablet, since it's not just on one router. I'm at a loss on how to fix this and the only thing I can compe up with atm is to try a factory reset, which is weird, since the problem was with the tablet literally from the beggining. Any help will be appreciated! Thanks in advance

I haven't really encountered that problem on my device. If you still have problems with the device after factory reset I suggest you try to get a replacement and see if it fixes it. You can also test if the problem goes away if your device is the only one connected to the router or setup a static IP. You can also post a logcat during the interruption so that we can get a better a handle on what is happening.

Try to re-flash your firmware and then install root. There is an application that grasps the Wi-Fi, so it doesn't disconnect and reconnect everytime.

Never mind got it working by using a different browser.
Thanks for posting it, but Samsung's 'solution' [emoji55] is to simply disconnect and reconnect the wifi which I have already tried.
It's related to the device not the network as I don't have any issue with any of my other devices on the same network.
Maybe if they'd release some source code that actually worked I might be able to do something about it instead of them refusing my request.

Mine too. I have the T280, Best Buy has the T350 for $20 more. Has dual band wifi. Might try exchange it, but I rooted it already. Can I go back to stock without them knowing?

I was dealing with this issue although it was never more than an annoyance because it never actually interrupted my wifi connection, it just showed the little toast message that said it reconnected
I somehow magically got the device to stop doing this and I don't know exactly what fixed it, but I think the step that did it was flashing the stock firmware to the device. After that, it never seemed to have the annoying bug again.
The other things that could have done it relate to installing root and using Link2SD to disable some bloatware and moving all user apps to the SD card, but my guess is the fix came from flashing the stock ROM

I have the same problem with SM-T280 (T280XXU0AQA4), tried many wireless network and I have always disconnections. There is a solution for this problem?

Also for me since day 1

I have the exact same issue with my A6 10.1.
Posted about it a while back, I tried a factory reset, i tried clearing the cache. I took it to the service centre who did a complete software rebuild. I reset my router to factory and gave the tablet a static ip address. In the end I got a replacement, the replacement has the exact same issue. A friend bought the tablet the same day I did and has the exact same issue, they also got a replacement, their replacement also has the issue. So that's 4 out of 4.
Samsung couldn't care less, I've called customer service who suggested taking it to the service centre or getting a replacement, both things I've done. I've emailed and received nothing but generic cut and paste replies telling me to factory reset and clear the cache partition. I'm over my 30 days and can't return it. So I have a lovely paper weight and I'm back to using my iPad 3 because it may be slow as anything but at least it stays connected to wifi.

I have the exact same issue with my A6 10.1.
Posted about it a while back, I tried a factory reset, i tried clearing the cache. I took it to the service centre who did a complete software rebuild. I reset my router to factory and gave the tablet a static ip address. In the end I got a replacement, the replacement has the exact same issue. A friend bought the tablet the same day I did and has the exact same issue, they also got a replacement, their replacement also has the issue. So that's 4 out of 4.

It may not be Samsung's problem but the place where you bought your tablet from. You might have to reflash it to stock (the ODIN way or the Samsung Smart Switch way). Some stores refurbish items and just take the same item repackage after thinking that it is okay to use because they just hook up the tablet to the computer without it actually connecting to the wifi.
If you want to do the ODIN way, you should try going to www.updato.com and find your software and device number and install it. There will be a guide there.
If you want to do the Samsung Smart Switch way, just go download it for the PC and it should tell you how to do it. (YOU NEED YOUR DEVICE NUMBER AND SERIAL NUMBER!)
Or if it still doesn't connect online, it might be because the host file is messed up. It is located in ./system/etc./host
I'm not sure but you should be able to find it through ES File Explorer.

Thanks but I took it to the local service centre who reflashed the firmware and it made no difference. Support told me it's a known software issue but they don't know when or even if a fix will be released.
It connects to the wifi fine, it just drops connection constantly, it shows as connected and I'm sat less then three feet from my router but try streaming or opening play store and it says no connection retry. Then you have to wait until it decides to work again, sometimes that's seconds, sometimes a few minutes. Sometimes you have to manually disconnect and reconnect wifi or turn the device off then back on. Rince and repeat.
I'll download smart switch and give it a go but I don't see it helping to be honest.

Try rooting your device and then check your hosts file and fix it. Sometimes, after when I installed Freedom (In-App purchase hack) it updates the Host file to disable it to connecting to the Internet. It should only say 127.0.0.1 Host, not something like app referrer: 108.xxx.xxx

Thanks but I honest'y can't be bothered with it anymore. As I said myself and a friend got the same tablet, we've both had the same issues, we both got replacements, both the replacements have the exact same issue and I assume it's massively unlikely all 4 tablets have host file issues. I've wasted hours of my life on this (resetting my router to factory for some reason caused my wifi printer to flail which took 4 days to fix). I've not rooted it and haven't installed anything that should mess with the host file.
I may change my mind and give it a go one day when I'm bored. I assume rooting doesn't invalidate the warranty/trip the knox etc?
I ran smart switch last night, backed up, reinstalled the sofrware then restored from backup. Only the backup didn't restore all the app settings, so it removed all the progress on the games I had been playing.

Root does trip your warranty and it is a pain in the but when you are trying to install applications like Oasis's Island app because it knows if you had a "modified" OS. So, you have to be careful on what kind of application you still want to use.
If you can get another replacement or exchange, reset your device and then hand in to the store for a SM-T350 or some other device.
I know that SM-T350's are good for games and other content like watching videos.
Hope I helped and I wish you the best of luck.

The T280/T285 doesn't have knox, so nothing to trip.

Can confirm reflashing stock did not fix it on my t280. Starting to think the only fix is to get a different tablet...

Wifi issues?

Sorry if this has been discussed before. I just can't find it anywhere.
Is anybody having any Wi-Fi issues with their S8? What is happening for me, is that, I connect to my home private Wi-Fi network. Then 10 seconds later the network completely disconnects. Then approximately 10-20 seconds later it reconnects again. It keeps doing it over and over and over, non stop in a cycle. So I completely disconnected from my Wi-Fi, and I'm using my 4G LTE. I started noticing this at home, but then as I go to other to other Wi-Fi networks it's he same issue.
I even did a factory reset to the phone because of this issue and a home button vibration issue, where the vibration would not stop even in standby mode. It was also causing the Android OS settings to even be disabled, and not let me go into the OS serttings from the Android OS taskbar menu button, or the button for the settings in the app drawer. The factory reset did fix the vibration issue, but it didn't fix the Wi-Fi issue at all.
Also, is anybody else having this exact specific Wi-Fi issue I'm having?
Thanks in advance for all the answers and feedback!

You need too update your phone through the Samsung Apps app. Samsung released a fix for the wifi issue.

I already am up to date with all the apps in the Play Store and the Samsung store. I even contacted Samsung, and the woman on the phone on her own just completely connected me to a manager without saying a word to me. The manager ended up saying that he never heard of this and made a bug report so they could look into it. It's also not in their system, according to this manager. This was today around 5PM EST

It could be a hardware issue. Have you thought about exchanging it?

I already did. This is the second device to have the Wi-Fi issue. I just received my replacement device in the mail today around 4PM EST, which is the device I'm talking about here.
The thing I'm thinking is, that maybe if I went back to the direct cell phone providers store and did a buyer's remorse exchange. It could just be a batch of phones that have the same issue. Which more than one from the batch could be located at the same store. But since I'm in Florida, and the replacement device came from somewhere in Pennsylvania it's a completely different batch. Which the Samsung manager agreed with me. He even told me what I already know, that even if Samsung tests the phone. People in the real world using the phone, may encounter issues that Samsung never found on their own. He also went on to say that it's vital, that people in general, especially people that are tech savvy and semi tech savvy call in, because with us calling in it can help fix the issues that Samsung may have never encountered on our own. The manager also said, that there can be more people with the same exact issue, they just never called in and reported it like I have.

What kind of router are you using? Have to tried another? Go to a Starbucks, or some other free WiFi spot and test. So far with you it's been a 100% issue. I'd start looking at different things.

Like I said in one of the above post, that I noticed it at home first. But as I used other Wi-Fi's I noticed it was an ongoing issue. I've tired my home private Network, my work private network, and at a few friends houses.
The manager from Samsung, honestly believes that it is a Android OS bug.

It's not a big deal, I completely understand. So what else do you think I should try?

I also have issues with Wi-Fi similar to yours, if anyone has a solution, please let me know

Have you made sure that in settings you have a tick on "Keep wifi on durring sleep" ? Also for the sake of it, switch off "battery optimization" for all apps and see how it behaves. Also make sure you swithch​ off the option "smart network switch" under WiFi settings. What your phone is probably doing is constantly trying to switch between the WiFi and mobile data, or the power management puts it in sleep to preserve battery.

Well instead of getting the same same old suggestions (which Im sure you tried, all of them) you can read thru them all here in the thread that already exists:

Keep Wi-Fi on during sleep is activated. But it has nothing to do with that because my phone goes to standby mode in 30 seconds. While as soon as I connect to the Wi-Fi network, 10 seconds later it completely disconnects me. Then 10-20 seconds later it reconnects me. Then it repeats the same thing over and over. The phone can be completely in use, or it can be in standby mode, the same problem still occurs. Also the same thing goes for battery optimization, while it's on and off.
It also appears that someone else on the first page is having similar Wi-Fi issues. So maybe, a few of the many mass produced phones are having Wi-Fi issues. So maybe it's really an OS bug like the manager from Samsung on the phone yesterday was telling me.

Hi All, even am having a same problem, am here in Saudi Arabia and when i spoke to samsung Persons they are not showing an exact root of the problem and not even willing to exchange my mobile. this issue is with my mobile since 3 months and am waiting for upadte , i got 2 updates till now but none solved my wifi problem, i donno what to do

I can say this only happens to me when I have Bluetooth on and my watch connected and when I'm on a 2.4 signal vs a 5....and if by chance is your phone with sprint or verizon?

Android Oreo - "Mobile Data Has Run Out", but I still have lots of internet quota.
whenever you're on cell connection, and lost signal. when the signal got strong again, there's notification from mobile carrier "Mobile data has run out", "Tap to visit *operator* website"
you could fix this by activating and deactivating airplane mode. It's so annoying.
Does anyone experiencing this?

Not ever. Which carrier/MVNO? Maybe it's time to get a new carrier/plan.

Yes, I've been having that message ever since the first boot after updating to Android O about three days ago. Toggling airplane mode on and off fixes the issue for about couple of hours. Battery also drains like crazy.
Now, today is the first time I'm out of the house away from wifi all day and I haven't get the message again. I'm back on wifi for about two hours now and all is well. Battery also seems to be back to normal. Hope it stays that way.

Well, if the cell signal is strong that doesn't seem to happen. But if you're on weak signal where you could lose receptions, then that happened.

@Rollies77 Telkomsel, Pak! My driver used XL and always had problems. Don't know how you upgraded, but you could try downgrading your radio. Just fastboot flash the previous modem.img. (v3.81). Current version is 3.84. The radio is independent of the ROM version so it will work no problems. The older radio from Nougat may get your service back.

Yup, XL Axiata. Just happened again. Gonna try downgrading the radio. Thanks.
Edit: No luck. Flashed 03.81 radio, reboot and greeted by "mobile data has run out" message.
I upgraded to stock OPR6 from Google's factory image. Clean flashed. Happened on first boot before rooted. But yeah probably XL is acting up.

I'm on full stock, not rooted. So i don't think i can flash the radio.
So it's the XL's fault. I don't want to change my number, and i'm staying away from Telkomsel, their call center is the worst, also in my work place and home their signal is not very good.
Anyone not using XL experiencing this?

Correct, can't flash the modem partition with a locked bootloader. You could stop by any kiosk and pickup a simPATI and you'll quickly know the answer for very little money, but I tend to agree with you that XL is probably the culprit, and loading 8.0 was coincidental. I always had good service with Telkomsel, and was impressed by the service at their graPARIs, especially at Pondok Indah. There are also some settings to experiment with under Dev Options (don't have to be rooted). One is "Agressive Wi-Fi to mobile handover" and the other is "Mobile data always active". Toggle those and see what happens. Good luck. :good: @Rollies77

Will try that on the Dev Options. Especially the "Mobile Data Always Active"
It's not graPARI's services that are bad, but their unified call center (147), My friends are experiencing bad service from call center (angry at customers, blaming customers for the problems even though the customer actually an IT guy), The product is Telkom Speedy, not their Mobile products. But they are still using the same 147 Call Center right?

google knows about this bug - have for a while, taking their sweet time to roll it out in the november security update.
I just upgraded to Oreo today (Project Fi 6p) and it completely cuts off my XL data in Bali.
Good job google.
There is a message at the end of this thread that suggests removing an app to fix it... I guess I'm going to give it a whirl.
