Hi all,
I currently have T-Mobile (US) as my provider, and have just switched to Cingular this weekend. I have the T-Mobile MDA and want to know if it is possible to use my phone on Cingular's network. What do I need to do to unlock the phone and sim successfully to work on Cingular's network? Do I need to put Cingulars ROM on my phone to make it work? I've already tried loading their ROM on the phone, putting in their sim card but it doesn't work, I get an error telling me that the network isn't unlocked and asks me to put in the correct code to unlock the network.
Any thoughts/ideas/help?
Thanks I really appreciate any help!

Search the forums for "Unlock Wizard". You should come up with many hits, mostly around a program called lockowiz. It will SIM and CID unlock your phone.

You're gonna need another sim to do it.
used good att sim it did nothing
i used my brothers att sim straight outta his phone...it did nothing...??
I have a European I9100 and a t-mob T989 (both gs2) and swapped the at&t and t-mob Sims they both phones worked. However the network features were non existent.
Here's the issue. I purchased the At&t s3 (SGH-I747) last year. Long story short, I wanted to go to T-Mobile prepaid with the same phone.
I purchased the SIM activation kit for $10, popped my SIM in and it worked!
Before I put the SIM in it though, I paid for an unlock code. I still have the code.
No 'Network Unlock' screen.
No prompt for my unlock code.
I am getting H+ speeds with the at&t s3 on T-Mobile prepaid without doing ANYTHING.
My question is:
Why cant I get to the unlock screen? I have tried to dial "#7465625*638*# for the prompt to popup and NOTHING.
Can someone tell me...
1. Can I flash a T-mobile rom to this phone? (every time i try I get a build.prop error, even after changing the model to the T999 and all that jazz),
so I can't install a T-Mo rom?
2. Do I have to flash a modem/radio or anything else like that?
3. Or, should I just continue to flash At&t Roms with the t-mo prepaid sim?
I have searched for a while now, and noone has my problem. I never expected to just switch sim's and it would work, so ANY help would be appreciated.
Thanks!

in the general section is a thread on converting an i747 att to a t999 tmobile
Hello.
If you have signal then why are you trying to use the code? It is unlocked already!
im not an expert but this is what i know from reading a lot:
1.- I installed a t-mobile (t999) rom modified to work in a att s3 (i747), i think you can flash a any rom from the t999 section (i am not sure about this)
2.- Do NOT try to install a modem from t-mobile or you will hard brick your phone.
3.- Thats a good idea, do it and let me know if it works.
I used this files to convert an i747 to a t999 http://forum.xda-developers.com/showthread.php?t=1771021&page=25 (read from post #246) so now i use customs roms for the t999 i did it because where i live do not have good signal, was stuck at edge and with those files now i have 3g signal.
Btw, i am in the $30 prepaid t mo plan.
Thanks all!

Hi Guys,
Few days back I took a contract from T-mobile UK and want to unlock it. I thought from the forums easily I can follow the procedure and unlock my phone but it is not happening. I'm not getting the screen of service mode where i can see UMTS so that I can follow the other steps. Can anybody please tell the code to enter the service mode window so that i can try myself. It will be a real help if you can help me otherwise I'm totally screwed up.
I bought a roger's locked noteII from canada but the owner told me that it cant get gsm network so it can works as a wifi tab...
Is there any way to tell me can I repair it myself softwarely
Or I must go hardwarely change the sim card slot ????
I neeeed help please
no one can ??
help me please
More info...
Did the previous owner tell you why the device won't get a signal ??
Is the device damaged ??
If not...you can carrier unlock the device to use with the ATT network...
There are numerous threads that cover these steps...g
Edit:
Start here for carrier unlock...
http://forum.xda-developers.com/showthread.php?p=34661189
Once you succeed with unlock.
.you'll need root and recovery to flash a radio image....and set your APN for the proper network..
Do some searches....you'll find everything you need....g
Noticed your other thread about changing the SIM holder...
That's likely not the issue as stated above....g
thnx very much i'll tell u about the news
please help me
the servicemode screen become black no any choices after i played in it roughly
could it be solved ????
i flashed the original rogers rom but invain
