[Q] Straight talk S4 to TW Tmob - T-Mobile Samsung Galaxy S 4

I am pretty sure this will work, but I want to make sure before I buy. Straight talk S4 is $250 brand new right now and I want to use it on T-mobile. I can flash with a touchwiz rom, put in my Tmob SIM and enable the Wificalling, correct? Wifi calling is essential since I don't have T-mob service at my house. Thanks!

You have to SIM unlock the phone first. Once you have that and rooted, you can flash a ROM with WiFi calling if you can't use it.

Bad part is that tracfone locked down this phone really good. Even with the Sim unlock code the phone does not get fully unlocked. Have to enter the code everytime you power on the phone. No 100% unlock method yet, you can flash a custom ROM, but that's about it. No radio flashing...etc.

can you rewrite the IMEI to it, that unlocks others like S4 M919 and several 9300 variants

[Q] At&t to T-Mobile prepaid

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!

Question about Network Unlock

Hello all,
I have a Samsung Galaxy S III from AT&T.
I plan on traveling so, I wanted to unlock it. I followed the steps on Android 4.1.1 I believe and it seemed to work (my menus looked identical to the tutorial I followed, but I don't have another SIM to test with). But, I have had the phone for a while and it is really sluggish, so I backed it up and decided to do a hard reset. The phone is running much smoother now, but I did do an AT&T software update which brought it to Android 4.3, and now when I look at the menu after typing *#197328640# and following the steps, when I get to Network Unlock, it looks different. Did the update relock my phone to the AT&T network. Is there a way to verify? Should I just hard reset again and stick with 4.1? Pleas let me know as soon as possible as I am traveling soon.
Thanks for all the help
If your phone was unlocked using any method, it should not relock. You can test it with a non att sim.

How do I test if I don't have access to a non ATT sim, I have one Korean SIM card, but I don't know how to test with it because it is not currently being serviced.
Put in the non-ATT sim, power up the phone. If it does not ask you to enter an network or carrier unlock code, the phone is unlocked.

it shows no signal, but does not ask me for a network or a code. So it should be fine right?

Note 2and Note 4 similar questions

I have a general question for my note 2 possibly moving to a note 4. Can someone tell me the difference between unlocking a phone ans rooting. My note 2 is att and rooted and have it on the straight talk Sim. I picked up a new note 4 for 300 bucks can rooting it do the same as unlocking it.
I'm not in USA but believe I can help clarify. Unlocking relates to the ability to use your phone
on a different network than what it's locked to.
Rooting is completely different, it gives you total control over your device. However be aware that ATT version of N4 is locked up tight and cannot be rooted at the moment. May I spontaneously combust if my facts are wrong.
Hahaha OK well thank you I'll get it unlocked for starters. Straight talk runs on the ATT network so I'll get it unlocked to safe
What is the best way to unlock a phone? Is it a similar to do like flashing via Odin?
You purchase a code, then you put in a different carrier sim card, then type in the code, and the phone is carrier unlocked. No flashing necessary.
Rooting means gaining access to the file system of your phone to install apps, delete files, etc.
If you have no warranty on your phone, you may be able to downgrade to 4.1.1, unlock, and run OTA updates to get back to KK.
I have the Canadian version (sgh-i317m) of the Note 2 that was running the latest 4.4.2. I used Odin to flash back to stock 4.1.1 which tripped the knox counter, unlocked, and flashed back to stock 4.4.2.

[Q] Pls Help! Need to determine unlock status asap. Also, USSD codes failing

Hi.
I am unsure if my phone is unlocked and can proceed with porting my number over to Metro PCS. Please help me with advice how to proceed. I decided to move my service to Metro PCS since they are now a Tmobile company and after lots of research, I found that I can use my current phone/software as long as it was unlocked. I recently purchased my Galaxy s4 second hand and assumed it was not unlocked. I had immediately rooted it and flashed a new rom (Insane Kitkat 4.4.4). The phone has been working well. I already have requested and have my unlock code from Tmobile.
When I went to the Metro PCS store to port over my number, the phone did not request an unlock code when inserting their Metro PCS sim card (not activated). They said that my phone may already be unlocked or that it may not need to be unlocked since Metro is now owned by T-mobile. They stated that it may work if they go through the entire registration process, port over my number and activate it but that it would be a gamble. If it did not work, then I would not be able to go back and reactivate my sim immediately with Tmobile since it would then be in deactivated status with them.
I tried to find out if it is already unlocked by *#7465625# but my phone will not run this or any other USSD codes to verify. I keep getting errors when trying any USSD codes. A message says 'USSD code running' then "unable to process request".
A friend of mine has an activated Galaxy S4 on Metro PCS and I tried inserting her sim card to prompt for the unlock code but my GS4 just booted normally then showed 'not registered on network'. It did, however, have cellular signal bars. When I inserted my Tmobile sim into her GS4 it did ask for the unlock code normally.
I am at a loss now..
funny, I like to know if there is a way to check carrier unlock status for simcard without having to put a simcard in.
T-Mobile phones work with metropcs without the need to unlock
Could the custom rom be suspect?
Maybe need a stock rom to get carriers sorted out, then go to custom roms.

I ended up contacting Tmobile and they stated that the phone showed unlocked status already but I think you are correct. I wasn't aware they could tell me this. It was very fast and super easy to find out.
I have the phone working great on Metro PCS now. USSD codes still failing though...

[Q] Flashing Stock from another company?

So I'm on the same boat as several others, got a T-Mo S6 Edge to use on another network, bought the unlock code, doesn't work so I can't use it, however, the carrier I plan to use it on (Claro Dominicana) also has the device and I found their stock ROM online (http://www.mrcrab.net/viewstockrom/34045-sm-g925i.html) Would I be able to flash this, a 925i ROM into my 925t device without issues? As I understand the issue right now is that there are no unlockable ROMs for the Edge in the US.
