Hello,
I recently got a Telus S3 that I unlocked, rooted and installed CM 10.1 RC5 (d2att) but am having network difficulties with a fido micro sim card.
Occasionally I completely lose network reception in urban areas and get a "network error" diagnosis from my phone, I would be disconnected from my cellular network for a period of time ranging from a minute to 5 minutes.
I've tried my micro sim on another phone and that does not seem to be the problem; I've inserted a rogers micro sim into my S3 and it also did not appear to have any problems with the network.
One last thing I tried is to restore to a previous nandroid backup of a stock unrooted rom and so far it seems to have solved it.
I really like running CM 10.1 and aside from the problem that essentially renders my phone inert, is there a way to fix this in CM10.1 itself?
Thanks
I personally have no issues at all with that but i am on a different network which is ATT. How did you flash the ROM? Did you flash clean or dirty? That can make a difference. Then lastly, have you checked your apns phone under network part of settings.

I did further research and found out that there is a problem in CM10.1 where the change from 3G to 4G causes disconnections. I disabled LTE and the network is stable now.
Thanks for replying!

I have a problem with my telus i747m, I have unlocked it and am trying to use it on rogers but cant. I have tried different sims.
My problem is I dont have a network connection all the time. When I do have a connection as soon as i get a text or try to make a call the phone looses the network connection, when making a call the call gets through but the phone looses connection and the call then gets cut.
no data connection at all. I have rooted the phone and tried flashing the modem posted in development section but it did not help.
do you guys think its a hardware problem, or software?
also when no network is connected and I try searching for a provider it ask me to insert a sim. I have tried different sims and both work fine in another s3 i have.
The phone has a strong signal when it connects to the network and then as soon as the 4g pops up or after a couple of seconds the signal just drops and loses the connection. Then it will keep on getting a signal and instantly drop the network connection over and over again. i have another s3 i can try swapping parts but i dont know what to swap.
hellpppp meeeee!!!
Ok i used rf nv manager andbthe imei is fine.

There is a specific Rogers modem that you can try flashing, other than that, I'm stumped.

lol yeah its a odd problem. ill try flashing that, the modem listed here http://forum.xda-developers.com/showthread.php?t=1831898 says rogers, telus, bell is this what you are talking about?
thanks
update so i was about to try flashing the modem again, i poped in the sim turned on the phone and noticed the signal wasnt dropping when wifi was connected. I then shut of wifi and as soon as the 4g symbol poped up the network connection dropped, I then shut off data and got the signal back i havnt lost it sinse and i made a 40 minute call to rogers with no issue; I have full bars.
so it seems when data is turned on the network gets disconnected. hope this helps in finding the problem.
i played with the settings a bit and this is what happen:
GSM only + data enabled = phone works fine
HSPA only + data enabled = as soon as 4g pops up network drops
GSM/HSPA (auto) + data enable = as soon as 4g pops up network drops
GSM/HSPA/LTE(auto) + data enable = as soon as 4g pops up network drops
all of the settings work if data is disabled.
I have just flashed the latest bell jelly bean leak and still the same problem with data turned on phone loses connection.
I have the same setup (Telus SGS3 with Rogers sim) as you but don't encounter that problem. You might want to try to use your warranty for the problem as it shouldn't do that on stock in the first place.

yeah i tried manually setting the apn too. didnt make a differance, also tried the rogers mvlle8 modem no differance basically the phone works with data off, or only gsm with data on.
I have another s3 i thought it could be the sim holder or something tried swapping that, it didnt change anything. do you guys think i should try swapping the antenna

its getting tricky to play with that unless you have a good knowledge about wat you doiong and that you may have no offense here
wat about the warranty ?
I bought it used and have already opened it up to try swapping parts wwith my other s3, also have flashed it with custom rom and im guessing the previous owner did aswell because the flash counter was at 5 I think ive voided the warranty. Im pretty good at taking things apart and not afraid lol. I was a mechanic so yeah.

Check your APN settings. On stock, when I switched sim cards, the secondary provider didn't have any and they needed to be added manually.

im going to smash this thing with a hammer.
ok no im not but i feel like doing it.
I'm just wondering if anyone else has noticed this and this only happens after a period of time where the LTE will just stop working but if you switch to CDMA it's working fine?
To go a step further I've wiped the phone and restored to stock. Once that's done LTE is working fine.
To go further again, I grabbed a different ROM and the exact samething happens, I'll be able to be on LTE for about a day and then the service stops and if I switch it to CDMA I'm good.
Just wondering if anyone else here has noticed that.
Cheers,
did you verify your APN settings?
i'm using a Bell version GN2 but on Fido and i can flash all day everyday and 4g has always worked.

The APN settings are always the same with Bell. They don't change.
HSPA+ will work but LTE will die after a little while. (This only occurs on other ROMS). If I stay on the stock rom there's no problem.

On a different note... I noted that if I have SAMBA Fileshare on I have strange things that happens DATA wise.... I'm still looking into it and dropping logcat and looking at different possibility.
At this point it's looking like something with the SMB Fileserver I have on the phone. (Will know later on)

im not saying the bell apn has changed but ive found that sometimes when flashing roms, the apn settings arent included in the rom and have to manually be entered.
This happened alot when using my galaxy s2 lte.

I currently have ATT service with my S3. I'm running the Intergalactic 3.0 at the moment and I absolutely love it. However - I just switched to T-Mobile. I want to keep my current phone and sell the free S3 they gave me so I don't have to deal with losing any information or anything like that. Can I get away with this on the ATT based ROM? IIRC T-Mobile and ATT run on very similar networks/frequencies. Any advice would be helpful here. If worst comes to worst and I have to use the T-Mobile provided phone, can I flash Intergalactic on it as well or do I have to choose from the T-Mobile ROMs on this site?
Thanks to everyone in advance.
You should be able to add the proper apn for t mobile. You also may want to flash one of the t mobile radios.

I just switched from ATT to T-Mobile. I have an ATT SGS3 running Task's AOKP. APNs filled themselves in when I put the T-Mobile SIM in and everything works flawlessly.

Strange. I unlocked the phone, I was able to put in the SIM card and the APNs filled themselves. I was able to make calls and texts but unable to use internet. Any idea here? Using Intergalactic 3.0
To clarify - no internet at all. No Edge, GSM, or LTE

No idea. I'm not getting LTE, but I do get H+ and haven't looked into it yet. Maybe it's the ROM? I'm on Task's newest release.

Strange. I went back and re-registered on the network through the settings and now it's getting 4g, just no LTE. At least it's working though!
Edit: Kinda. It worked for a minute then I locked/unlocked the phone and it didn't want to work any more.

I just changed the setting under settings-> network mode to "GSM/WCDMA/LTE" and now I do get LTE
So I recently got a T-Mobile GS4 for use on AT&T. I have set up the APNs, etc. and everything seems to be working, except for one annoying thing:
The device seems to be reverting it's Network Mode to WCDMA preferred instead of LTE/GSM Auto. I have tried setting this in Settings as well as in the Testing mode menu and it will not stick.
This happens every time the phone is booted, as well as when a call is made. When the phone is booted, it takes a long time to connect to the network, and when it finally does it is set to WCDMA preferred. I can then change it manually to be LTE/GSM auto.
When I make a call, the network drops from LTE to H/H+ as expected. However, after the call is completed, the network connection drops entirely and reconnects a short time thereafter but on WCDMA preferred.
Has anyone else experienced this issue, or have any ideas? If it makes any difference, I am running the latest CM10.2 for jfltetmo, without any other modifications.
Thanks in advance!
EDIT: I should add that the IMEI on file with AT&T is indeed for an AT&T LTE phone.

What I would do to solve this problem is to first go into recovery and make a nandroid backup.
The problem you are having is due to the fact that you are running CM10.2 rom which perhaps
is not 100% compatible with your specific phone and or carrier.
What you need to do is to flash an AT&T custom rom OR better yet flash Darthstalker's
AROMA Multi-Carrier rom and select AT&T after the rom starts flashing.
That way it will not only flash a proper AT&T rom but it will also flash the
proper kernel which you need if you want to use it on AT&T as well as
setting it up with the correct APN's which will stick.
The Darthstalker rom can be found here: http://forum.xda-developers.com/showthread.php?t=2292054
This rom has a lot of extra features, settings and options making it one of the best roms around
especially for someone like you who wants to use a tmobile phone on the AT&T network.
Give it a try, I am certain it would perform really well for you without any issues.
Good luck!
Thanks for the info. Looks like that is a TouchWiz ROM though... I'm looking for an AOSP one... Will look more

On second thought it would be a good idea to try this to see if the problem is eliminated. In the meantime, do you know of any AOSP ROMs that might have the same type of solution?

I've had my T-Mobile GS4 on ATT for a few months now and have had no problem with LTE after they had my phone's IMEI, and I was using the correct APN. This is the case on many TW and AOSP ROMs that I've tried. Good luck!

same here i have an m919 rooted stock mdl rom on at&T and have no such issue mine stays on lte.. both with phone or pta ap.. Have you tried reflashing and factory reset before setting stuff up...
Thanks to everybody for the info. I finally got it working:
I first backed up to the Touchwiz ROM mentioned and made sure data was working. Here I had to manually add the APN and then the settings stuck after reboot, calls, etc.
Then, I reinstalled CM 10.2 for jfltetmo. Magically, the setting is now sticky.
Thinking about it, I got the phone, unlocked it, and immediately installed CM without attempting to use the ATT sim card at all. Perhaps TW does something to make this stick, but I have no idea.

Hi,
I have an unlocked version of Fire Phone and have flashed the almost latest version of the Cyanogenmod ROM. I am using at&t wireless service but it seems that I just cannot use LTE. Based on other information I think the phone supports all the bands at&t is using. The network the phone is using is HSPA. I tried changing settings in the phone but it did not help. I searched carefully using related keywords but have not found anybody talking about this, and I wonder whether this is something too simple to ask or nobody else has ever encountered this problem. I want to know if there is something I can do to use LTE.
Thanks.

I have seen some issues about CM based ROM's and ATT LTE. Did you have a full LTE signal and good data speeds on the stock ROM before you flashed the CyanogenMod ROM?

Thank you for your reply. Unfortunately, I had already flashed CM before I switched to att so I do not have information about that. And currently I am not quite willing to flash the phone back to the native fireOS just for this because HSPA still gives good data speed...

Have you checked your APN settings and verified that it is setup correctly to use ATT LTE? Also, was this phone ever used on ATT before with the sim card you put in it? If not, then what will have to happen is this, I think: I found this excerpt which I believe is what will have to happen.
You WILL NOT get AT&T LTE on you phone unless your account is first provisioned with an AT&T LTE Phone. There is NO WAY around this. You must buy/borrow an AT&T phone that has LTE capability, put your SIM in that phone, and let the system provision your account for LTE automatically. This is NOT something that customer service, or a store clerk, can do for you. Once your account is provisioned for LTE (you will know because the LTE indicator will show up on the phone), you can then put the SIM card into your Fire Phone. At that point, the device will automatically select the "phone" APN, and you will get LTE (identified by the "4G" indicator).
Hope this helps
