Hi, noticed this can happen if you are somewhere and you lose all your signal....won't reconnect to data when you get a signal again.
Turning phone off/on, data off/on, airplane off/on doesn't help..... only thing that worked was in network settings - change to 3G/2G only, then toggle back to 4G/3G/2G auto....seemed to kick it back to life.

Thanks finding out now that nobody can call me and can't call out if I do it goes to 3g then h then nothing and have to re insert sim if nobody calls I can use mobile data but still not the phone don't get it like when someone calls I lose the signal it goes off never had this issue and had plenty of phones could the sim connection be faulty?but then mobile data comes on and works it was all working fine for a week I'm baffled

Hi, not the same issue I was having...I could still make and receive calls and sms's.....just no data connection. Only thing I can suggest is trying a different sim card - if the fault appears with a new sim , then it's the phone at issue.

The following process helped for my problem which exhibited the same symptoms twice: 1. Switch off the phone; 2. Pull out the sim card and insert it back; 3. Switch the phone back on. Hope it helps

No mate in uk been fine for a week no issues never did anything different can't work out if it's phone or sim but put my wife's sim in mine and it does same with that try ringing doesn't get through and if someone rings me knocks my 4g and mobile data completely off never seen anything like it

Also should I have the reception bars there if no mobile data thought I just needed the reception bars to be able to call and text not 4g?am confused now

Read somewhere to wipe data and app or two by going into recovery but it doesn't do anything in recovery just blue screen saying downloading for ages but nothing happens so maybe need to root it

Is This Single Sim OR Dual Sim .... S7

It's for 1 sim and 1 sd card

I have a dual sim s7 edge. Unlocked. Decided to go with T-mobile. Data comes on for a minute and then disappears until I restart the phone again. Even though I select sim 1 as the one that should use the mobile data, when I drag the top of my screen where it says: "calls sim 1; messages sim 1..." it says data sim 2.... WHYYYYYYYYYYYYYYYYY?
EDIT: So I have tried various options time and time again for the dual sim mobile data issue. For me - it worked when I disabled sim 2, but when I re-enabled it, it started defaulting back to sim 2 for mobile data and it was effed. So finally, even though this is not ideal (but doesn't make 'real' difference), I replaced by sims - put my main sim (for calls, txt, data) in the slot for sim 2 and put my backup sim (for calls,txt) in tray for sim 1. It works without a problem so far (24h test so far).
EDIT 2: So after 48h, my mobile data started defaulting to sim 1 (which was now my backup sim, since before it was defaulting to sim2)... I have NO idea!!! Am I gonna have to change the sim placements every1-2 days??!?!?! Please let me know if you have any other fixes. Thanks

My phone worked fine for a few days and now 4g doesnt work any more only 3g and i cant find how to fix this

[Q] i9505 - No mobile connnection

Hello guys,
I've a problem with my phone. I have no mobile connection, but it isn't Modem related (I think).
It all happened when i went back to 4.3 TW (XXUEML6), I've always used broodplanks aosp rom.
First i thought it was a modem issue so i checked my modem but it was ML6
Tried to fix it with some reboots, wiping cache, factory reset, full reset and reflashing of both TW and AOSP.
I later flashed my previous modem, the problem still presists.
Now to get to the weird part: I've no mobile connection (No service) BUT can use my Mobile Internet and Wi-Fi.
Can't recieve/make calls, neither sms. But mobile internet works perfectly
I'm beyond desperation,
Can you please help me?
Greats

Blowed out sim tray and wiped sim.. Hope it's related to the sim and not the phone
If it was a sim problem, I wouldn't be able to give in my pin at boot, and wouldn't have any acces to Mobile Internet (not talking about Wi-Fi)...
Well it' almost 3AM here so have no-one i can ask for his/her sim. If you got any other suggestions I'm happy to try.
Reset APN else change your sim..
Send my signature phone to XDA with bad grammar
It can be your sim.I used a cut down one (iphone5) and put it in an adapter to make it a microsim.I had mobile data, but couldnt call or send texts.Used to happen daily, but sometimes phone displayed triangle=no sim inserted.Other times nothing was displayed (meaning I was fooled into thinking there was no problems).
Only once, for about 2 seconds have I had any problems with sim since I changed it for a proper micro one a week ago.
I thought it could be the sim holder also, as a few people have had problems with them.

Well strangly the phone has came to its senses overnight without doing anything. Now it's a game of waiting...
Because it happened a couple of times in the previous 2-3 days
A little "update": I've tried my sim in another phone, it worked.. Another sim in my phone also worked.
EDIT: I flashed stock XXUEML6 firmware and took care that I got "Official" (yes i've tripped knox a long time ago).
So far so good. So i guess latest official FW fixed the problem

The Curious case of my OnePlus 2 and Idea Cellular India

I have with me a strange problem to which i now have no idea how to tackle.
i got an invite for the 2 and ordered it the same morning i saw it. i was looking for a new phone, my phone 5 is maybe too old with the only physical buttons working being the home button and the volume keys.
The 2 arrived much before the expected delivery date and i was overjoyed.
i set it up, downloaded all my apps, set all that up and then inserted my idea sim. i had more than Rs. 100 as talk time balance with an idea2idea call rate cutter, idea2idea free sms and 3G data Packs activated.
i woke up the next morning and found my balance to be Rs.60. i thought i had overused the sms and payed no attention to it.
the next morning i noticed that my balance was now rs.30, and i hadn't used it much. i was curious now and called idea cellular customer care.
i told him about the balance being deducted and he said that the cause was international sms being sent from my device. i thought it must be something being activated and let it go again. Throughout the next day i noticed deductions from my available balance recurring in value of rs.3 and rs.5. i called up customer care again, this time he said this is a serious problem please have your phone checked by technician, it is malware app that is sending international sms.
i factory reset my phone and waited, by now my balance was rs.13. by the time i reached idea's office that evening it was 0.something. i repeated everything to them and they repeated the same stuff to me. i showed them that my phone was factory reset and hence the problem must be with idea. they told me idea has no international number service and then asked me to use the sim on an other phone and check whether deductions still occur. (recharged both numbers at this point)
i went home and popped the sim back into my iphone 5 and put in an AirTel sim into the OnePlus 2. Waited till the following afternoon, No deductions on both. I thought the problem must be solved and popped back the idea sim into the oneplus deductions again. Now i call up customer care again. this time i get the number to which the international sms is being sent (005859612 and another number which he told me ends in 7).
i remember the iMessage problems people face after switching to android from ios and then with some insane logic in my head i deactivate iMessage and Factime before popping the sim back into the OnePlus, thinking it will be solved this round. Not a chance, deductions again.
right now the sim is in an iBall slide tab, checking to see if the deductions occur on all android devices but nothing so far. i have no idea how what to do or even who to complain to. Any help is very very deeply appreciated.
Dude same problem here did u find any solution

I am having the same problem deduction are in value of 5 and 3 . it automatically sends SMS if you have find any solution please share . thank in advance.

No, sorry. Haven't found any solution yet. What I do now is that I keep my idea sim balance zero and use it only for data and SMS, the calls I do from an airtel sim.
Are you using idea also? And which phone did you migrate to OnePlus Two from?
I am using idea too and migrating from lumia 830

So this is a problem with idea then I guess. I switched from an iPhone 5 as mentioned in the post.
You are right . hey can you please tell how to slow down battery drain and heating issues on one plus two
I am using idea postpaid on op2 no issues at all. My other sim is BSNL prepaid. Works fine no deduction at all. Try posting a screenshot of ur running application when the deduction is done and I may find an Anomaly by comparing to mine.

It happens on idea prepaid only I think. My other sims work fine . plus I've tried resetting and everything so I don't think it's the app. Could it be a sim setting ?
I am using Idea prepaid as my second sim. So far no such random deductions. I think problem might be something else. ( Moved from Andoird one to One plus 2 recently )
Recently I found out that this app called 'hike' sent my whole contact list an invitation to join this app. Your problem may b similar as networks r dormant unless we use a service. Hope you delete an app which is making this fault.
Yeah. The problem is Oxygen OS sometimes doesn't show the "LTE" or "H+" or "H" or "E" and data connection arrows on signal bar, even when it's connected to the internet. I had this problem on Airtel too. I used to long press the mobile data connection quick tile and then switch off the mobile data just to make sure it's off. Now I'm on CM13. No Problem.

It's not a data connection problem. International SMS is being sent from the phone . confirmed with idea. The deduction occurs in rs.3 or rs.5

[Moto G4 with Amazon ads] Always losses carrier network after 24 hours

Hello everyone,
I just bought a Moto G4 16 GB with Amazon Ads for my wife, but we are facing a very annoying problem: the carrier signal always dies after 24 hours give or take. We tested with a different SIM card and the same thing happened. When this happens the device only shows "Emergency Calls Only" and we have to reboot the phone in order to get the signal back.
So, is anyone else facing this problem? Is this really a problem with this phone in particular or every moto g4 has this problem? Should I return the device to amazon?
Thank you very much for any information you can give me!

No problems here since I got my phone last week and I have T-Mobile. You might have to check your apn settings with your carrier.

I tested the SIM card in a different phone and it worked flawlessly (I also use T-Mobile). The strange thing is that the phone gets the signal very well during more or less one day, after that I have to reboot to get signal again.
Well, this is probably a problem in the device. I already asked Amazon to send a replacement.

Thank you, but I just use the t-mobile network. In fact, my carrier is called campusSIMs and it is a MVNO that uses t-mobile network. So, my APN configs are a bit different from yours.
However, I didn't know about this mobile data thing. I didn't touch the developer options. Maybe, it can be a good idea.
Thank you!
It won't be your APN settings since that controls your data settings. If the sim is ok then it could be your phone.

I'm seeing a similar problem with the data portion of the network (also on T-Mobile). While I'm able to send and receive calls and texts, data doesn't work. There's no indication that it's attached to LTE or even 3G (just a standard signal bar with no other information). I moved the SIM card back to the old phone it was in and it works fine.
Things actually worked yesterday, so something happened overnight to break it.

That could possible be the APN settings. Although usually it's the opposite, they don't work at first then they update from the network later on. Most times the APN settings will set themselves but on the odd occasion they need to manually edited. I don't use T-Mobile but the APN settings are easy enough to find.

Sounds like you need to manually enter the APN settings. What you describe is exactly what happens when it hasn't loaded an APN.
I'm "kinda" having an issue here. It's a little different though; the phone works ok for a while (for me about 3 hours, usually), and then I still get an LTE indicator, but have no network connection (get errors in apps/"No internet" page in chrome).
Other times, I lose LTE and get locked in 3g (H indicator), and can only get LTE back by going to Settings/More/Cellular Networks/ and toggle preferred network mode to 2g or 3g, let it connect (H or E), then toggle back to LTE.
Motorola responded to a bad Amazon review requesting I post asking for help on their forums.

I'm active over on their forums also and it's good to post over there in case you ever want to do a soak test. They look at your posts there when they ask for soak testers. As for your problem, I've seen it shift back and forth if you are in an area between towers and one isn't sending out LTE. If it were that I wouldn't think you'd get it back so easily. There's an app, don't remember the name, that will show the towers and signal relative to your location, If might be interesting to look at that.
Having the same issue with radio. Just replied to your post, Kalash.
Ok, we got a new phone from Amazon and it has the same problem. So, I believe this phone does not work very well with MVNOs.
I notice that the problem is that the phone cannot reconnect to the network after losing the signal. For example, if you go to an area with bad signal and, eventually the signal vanishes, the phone will not be able to reconnect to the carrier network. The phone only reconnects after reboot. Airplane mode does not solve the problem.
This does not happen with my Blu Life One X. So, I think it is a software problem.

That's not true on all mvnos' apparently. My wife's phone is on Consumer Cellular, an AT&T mvno and it's never done that. We've been in a no service area several times and it's always connected immediately when getting service back.

Very weird signal problems....

Hi all, tearing my hair out here and can't find an answer anywhere about my issue... Basically my. Phone displays emergency calls only,even though I have signal. My cellular data is gone. I have found that if I select 3g only my data and signal comes back and all works fine again. As soon as I select lte 4g the emergency calls only starts again and I can't use my phone. Phone was rooted and working fine. I have reset to factory settings today and then set my phone up again(which resulted in me losing all my documents and photos as I could not back it up...) problem still there though. I'm. Gutted as I've only had the phone a couple of months. Please if someone could help me out here.

Lost Mobile Data - HALP ME! (T-Mobile)

Last night I was in my basement, rocking out to some tunes on the treadmill. I noticed my signal had become very weak and the 4G/LTE icon was no longer in the notification bar. My signal is often a little weak in the basement, so I thought nothing of it and flipped on Wi-Fi. Couple hours later I had finished my workout and went upstairs. Turned off Wi-Fi and still had no data connection. I tried the phone. No mobile data. I reset network settings. No mobile data. I turned data on and off. No mobile data. I checked my wife's phone and she still has mobile data. I drove far enough away that I should've hit another T-Mobile tower but, still, no mobile data!!
I called T-Mobile. Went through every possible troubleshooting step other than a factory reset, but nothing worked. I really don't have the time for a hard reset until next week.
Anyone else have this problem or have any suggestions on how to resolve it?
Thanks in advance for your help.
Battery pull and leave the battery out for 5 minutes? Try your wife's sim card on your phone?
Same thing happened to me. In the backup and reset part of settings, there is an option to reset wireless settings. Worked for me. You will have to reenter wifi passwords and pair Bluetooth devices again though.

Didn't work. Neither did a hard reset. T-Mobile is shipping me a replacement overnight. I guess it works out because I have a nice scratch in the screen.

Updated from what? I was using the SIM card that came with my Note 7.
While I'm awaiting my replacement V20, I've now got the same SIM card in my S7 Edge, and mobile data is working just fine.

Sorry, but I don't buy into your mode of thought. Using the SIM card that came with the phone isn't going to magically fix mobile data.

i called and switched over to the sim card that came with the phone and never had another problem my signal and data actually got better, i started having signal and data issues a couple of days after i got the phone and switching the sim card out completely squashed all that just my 2 cents.

I lost ALL MOBILE DATA. Everywhere. Anywhere. Not a bad signal. Full bars pretty much all the time. But no mobile data.
