ok. i have a galaxy s2 from tmobile. i unlocked and rooted this phone.first i unlocked it with straight talk att sim. changed apn settins and data worked. bought the phone for 100$. when i tried to make calls i could not. i get a brief 1-2 second peak at signal meter then its replaced by a circle with line through it. i called tmobile and they said the imei was clean and clear. heres whats funny. the data works! i can surf and download big files yet cannot make phone calls. im rooted and no signal yet when i put sim in other phone it works flawlessly. i need this fixed quickly if possible.
Try different ROMs ( preferably stable ones ) or radios. I had working data and calls but no texts when I started using AIO after using the free unlock on the forums. Switching to AOKP milestone 2 fixed my issues. If that doesn't help, I don't know what would. :-\

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.

ok no im not but i feel like doing it.
Service state - not in service, no sim lock, imei not blocked, stock JB 4.1.2 clean from UK, never rooted, no mods. I cant call but 3G work PERFECT, I can use internet. What is wrong ? Full wipe and flashing stock via odin not help.

Hide your imei please. You don't wanna go around exposing that unique number to strangers.. might wanna turn your phone off, take sim cards out, wait a few minutes and try putting it back. That's what Vodafone told me when I had connection issues and it worked. Otherwise, calling your network operator will be your best bet

My guess would be hardware damage. You'll have to get it replaced

Got this phone with the problem already, I installed a custom ROM hoping that would fix it but still doesn't work.
Cannot find network, though it is showing 3 bars?
Can't make calls, can't use data.
WiFi works just fine.
EDIT: Should probablly give some more info:
T-Mobile model
ROM: CleanROM A.C.E.
SIM card works fine in my other phone.
EDIT2: Ok so after more fiddling I got it to pick up a signal from AT&T with the "Find Network" search. I'm thinking this has been locked to AT&T and I just need to flash back to a stock ROM and unlock it, thoughts?
I know I get T-Mobile signal at my house my other phone picks it up just fine and I'm using the same exact SIM in both.

Maybe someone has flashed a wrong modem/rom on the phone so it ruined everything..
You said it's T-Mobile phone.. I guess it's gotta be locked to t-mobile..
I would suggest to post this on T-Mobile Note 2 forum.. They would know a way to solve your problem.. This forum is for international note 2..

*#06 etc to get your imei display on the phone. Check imei matches with imei number underneath the battery. If they match and apeears to be valid you may have a locked or blacklisted phone. Blacklisted means its imei blocked nationally due to fraud such as lost stolen and insurance replacement provided etc.
Good luck

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.

Hey I just gave my d2tmo to my friend who has att service. Before I gave it to him I put it back to stock and unlocked it uusing a method I found here. Oh and I updated it.to the latest 4.3. When I put his sim in it worked fine it says att in the drop down menu and it has the singular apn. The data works the phone calls work but text did not. So I did sone googleing and checked the apn settings. It turned out I had to set the mms port.to it. After that the texts worked to my phone which is the note 2 but he says that he can't text his girlfriend who has att iphone. So does anyone know what could be causing this? I saw that another thing I can try is to change the mms port to 8080. I dont.know.if.that will work.
You can try and install the most updated modem and see if that's the case, for my AT&T GS3 I went from 4.1.1 (Unlock Method) to 4.3 and when I flashed the modem it had everything working on T-Mobile

That's another idea that I thought of. But I was explaining the situation to a friend and then it dawned on me. He had an iPhone so he probably has an iPhone data plan. He probably has to call att and switch it to an android plan. I know tmo's iphone, blackberry and android data plans are different so I bet that's the issue.
