Bell Galaxy S2 On Telus Network - Network Drops Every 10 Min

Hey everyone,
Had the Galaxy S2 since Saturday, unlocked the device, everything was working great. Out of no where, yesterday the phone still shows the H+ logo and full signal, yet i cannot send, receive text messages, initiate a data connection or make/receive phone calls.
In order to get all that ability back, you either have to 1) reboot the device, or 2) turn airplane mode on then off.
This only works for roughly 10 minutes before it all happens all over again.
I tried swithing to WCDMA only, but issue still persists, even tried some menu codes I found on another thread to disable H+ but the same thing happens.
This is currently happening on the bell shipped rom with no root or anything of the sort.
Has anyone experienced this?
I've searched for hours but can only really find complaints of data connection loss only. In my case it's everything. Data / SMS / Cell
Any help would be greatly appreciated.

I feel your pain, even though I have an XEU unlocked GS2, I've updated it with every update from kies hoping the issue would resolve.
Even with the latest KF3 update the issue persisted, however the phone could be used on Rogers with no issues, on Telus data drops constantly.
Disabling fast dormancy didn't do much to help.
However since updating the phone to KG3 2.3.4 yesterday I have not had the issue happen again. For the first time since I got the phone it no longer drops the data connection on Telus.

Thanks for the quick response. Was it only your data that disconnected, or everything else?
Also, may you please link me to the update? I suppose I could use that as a last ditch effort before exchanging the device before its too late.

My issue has changed over the past couple months, originally the phone would report that it dropped the network and when it came back data wouldn't work until airplane off then on or a reboot.
Lately things seemed fine with occasional data drops until yesterday, when it had full signal but I couldn't use data, sms or make a call. It was basically a paper weight until I updated it. The link to the file which has everything you need to update from samfirmware.com is below.

*edit - I'd make sure you have a back-up of your current firmware in case you need to flash back and return the phone.

I have the exact same problem. Bought a bell gs2 unlocked it and now with telus. My data dropped constantly and now I'm using the newest litening rom and now it only drops maybe once or twice a day so a huge improvement

If it's any consolation, I ran my Virgin SIM over the weekend (just to burn up the data I had to buy for a 1 month) and the same thing happened on stock firmware.
In my case, it would put me in "emergency calls only" mode, saying I wasn't authorized for the network (i.e. it wasn't recognizing my SIM). Tried the usual stuff (re-seating SIM, using the Telus SIM, reboots, cache wipes, network WCDMA/GSM selection etc), and nothing fixed it, it just seemed to come back on its own when it was good and damned ready no matter which SIM I used.
Flashed to "Frankenstein" KG3 on Sunday, and neither the Virgin or Telus SIM has lost network since then, in the same areas. WiFi seems to be working better too.

3G no longer working

Hey guys, been up all night and lost several hours of sleep already. I thought someone here might have some insight that can help me.
I have been running CM10.2, decided to go back to a Stock ROM today to update PRL + Profile (Not sure why, just thought I might need it to get connected to new LTE towers in Sacramento).
When booting the MF9 based rom it was asking to do the 'Sprint Hands Free Activation'. It doesn't succeed unless I connect to WiFi. But even if it does succeed, I can't seem to get internet through 3G. After activating I can call phones / text, the 3G icon shows, but no websites work...
On a CM10.2 rom calls and text also work, 3G shows a signal, but no websites work over 3G.
I tried ##72786#, it just forces another 'Sprint Hands Free Activation' with the same symptoms. I tried an Odin of MF9 but it did the same exact thing.
Please help, I can't survive through work without the ability to call/text people. Thanks!

Weird I can successfully ping google.com. So ICMP is getting through, but possibly not UDP/TCP... I am really confused what's going on. There might be a small possibility this is on Sprint's end, but I doubt it.

Wow.. I wasted a whole night on something that is probably Sprint's fault..

Now go get some sleep sir. I'm in Cali too so its 5 am. Lol

[Q] No 4G after reverting to stock.

Hey guys.
So I decided to update my wife's phone. It was running some version of stock rooted NAE from way back in the day. Noticed it needs NG2 modem for the NG2 Roms to work, so I just updated to Sacs V6 until I had a computer handily available to Odin to stock, then root.
Well, here's the thing. After a few hours of Sacs, her phone had rebooted a few times and kept losing connection all together then reconnecting back to 3g for a split second before disconnecting again. Well, I got a hold of the PC and Odin'd to stock NG2. Then rooted.
Well, now it won't connect to anything when LTE/CDMA is active under network mode, and obviously ONLY connects to 3g when CDMA Only is active. This is a big problem as the 3g service in my area is MISERABLE.(lol sprint) anyone have any clue what the issue is?
On a side note, I was getting 3g on LTE/CDMA before I decided to restore defaults in the APN menu. Now I get absolutely nothing on LTE/CDMA.
My s5 has perfect 4g LTE connection, so I know its a phone issue.(unless the s5 and s4 run off different types of LTE[I have no clue])
Any help would be MUCH appreciated guys.

Try ##72786#

Gave it a go. Nothing. LTE on my s5, still no LTE on the wife's s4. She's getting perfect 3g though. Checked ##3282# as well. LTE is enabled in there as well.

Okay. Soooo, she still has no 4g and 3g is continuously disconnecting again. Completely reverted to stock, noticed she still had NAE baseband. Downloaded the modem separately. Installed both. Now she is on NG2 baseband as well, but still having the issues.

Could be hardware issue. If you've reverted and tried to reset and do hands free activation there's not much going on with the software.

That's what I was assuming as well. She's only three months out from an upgrade, so she can just wait it out I suppose. We've got an iPhone 5 she can use for 4g in the meantime.
The only thing that had me confused was before updating the ROM, 4g was working just fine.

Everyone we flash or modify we are at risk of numerous problems and issues. Why the developers put a disclaimer flash at your own risk. (and she could've dropped it without telling you )

Sorry about the delay. It seemed go fix itself guys. Must've been a widespread network issue in my area. Thanks to everyone though.

[Q] Recieve only some messages after modem update

Hey guys,
I've had troubles with the disconnected SIM card reboot issue for a while, but it just came back hard, so I figured I may as well try upgrading the modem.
I upgraded to the newest rogers modem (I337MVKUFNI2) and I am having issues where I only recieve certain texts, but have LTE and can send them fine. When I go into about settings my mobile network state is "disconnected" and sometimes goes back to connected even though I seem to have reception. Now, I think I probably was also not recieving texts for the past ~2 days. I'm currently on 4.4.4 SlimKat.
Anyone experience something similar? Really not sure what to do to fix this.
Thanks
edit- Also, is there a chance this is hardware related?

Can't get signal on GRA-UL10

Hi, I need urgent help as I can't get a signal on my P8. I'm in the UAE using Etisalat and my phone is not getting a signal on C185B385 or Arrow ROM. It just happened without me doing anything. I've tried wiping data and it has not fixed the problem. I do have IMEI but it's always on emergency calls only. I don't think I was blacklisted my carrier either as I have transferred my SIM to my old LG G3 and it's receiving 4G signal.
Please help, thank you!

Many people are having a no signal problem with the huawei p8, atleast with 3g. Seems like there is no solution yet.
My 4g works and i can text. But if i try to make a call or change to 3g and 2g only I get no service.

The thing is, 4G doesn't work, nor does 3G. Huawei sure is great with their phones *obviously sarcasm* If I get a new phone, it surely won't be Huawei and will probably never be.
Although, I have discovered a workaround in which you put the SIM card in Slot 2 and set 4G to Slot 2, then put it back in Slot 1 and leave the 4G option in Slot 2. Sadly, it's only 2G but hey at least it works and saves a bit of battery with only 2G. But I need 4G, so I put my SIM in my good old G3.

Well my phone only has 1 slot so for me that wont work ._. (Gra-l09) I actually was lucky enough to win a huawei p10 that i will receive in 2 weeks. Hope i don't get the same problem. If I do I will never buy from huawei again either.

Woah that's great! Let's just hope your P10 won't have a problem because my cousin won a Huawei Nova Plus from a photography contest hosted by Huawei. And the phone reboots when he uses GPS lol. Again with Huawei's "great" engineering.

Try to reflash the stock rom and the stock recovery.

Tried to do that. Doesn't seem to work though. It also happened to me without me doing anything. Used fromfuture-home rom for a couple of weeks. Then calling gradually stopped working so I could only call sometimes. I thought it was my carrier so I made so many calls to them but they said nothing was wrong. Also tried to change sim. Now it does not work at all. I found a quick fix that worked for a while which was putting the phone in the freezer for a while. Feels like build 3xx for some huawei p8s causes a hardware fault. Everyone who has got this problem got it at about the same time.
Right now I'm using cyanogenmod flashed on top of 100% clean b321

I have the same problem in my P8: i have internet and wifi but i can`t make any call nor receiving
I flashed stock rom C900B370 without results
MelonsMasher, does cyanogenMod solve the problem?
Thanks a lot

My Huawei P8 (HUAWEI GRA-UL00) doesnt pick up 3G signal as well. One of the SIM slots is set at GSM only and it works perfectly fine. The other SIM slot is set at LTE/WCDMA/GSM auto but it can only access 4G only. When i try to call, it fails. When i set my SIM slot at WCDMA/GSM auto, it says 'Emergency Only'. I can be able to access data but no calls because, the system must fall back into 3G inorder to make a call.
What is the solution to this? It happened for me few times in the past and I have to hard reset the phone to get it back to normal. But then, all my contacts, pics and whatever i stored in my phone including email and social networking sites will be lost as well meaning I have to start all over again. Is there any way to solve this and not getting rid of what is stored in the phone already?
Thank you.
I may have to change my phone to other Brands if this issue is not solved.
