Can't unlock my phone.

Hi all,
I tried to unlock my phone with the code provided by cellunlocker.net and no luck.
Method 1: when I insert my t mobile card, it doesn't ask for an unlock code( it should cuz this is a non art sim card right?)
Method 2: after punch in #7465625*638*(my unlock code)#. Nothing happens. (It should say something like unlock successful or not right?)
Heck even I can't check the lock status of my phone. I type in *#7465625# and didn't bring up anything.
Method 3: i type in #7465625*638*# and wait for it to ask the unlock code. It did nothing. Didnt ask for anything.
How can I enter my code if my phone doesn't ask for it. And it locked cuz i can't use t mobile sim.when I inserted t mobile sum it says no sim card.
Plz help. Any ideas or advice would be greatly appreciated.
My phone is att i747. 4.0.4. Baseband i747uclh9.

I used the following on my S2, when I did, I am pretty sure I saw an option for the S3 as well. Might be worth a shot.

Also, are you on a stock or custom ROM? I've read that that can be a variable as well.

Thanks for the response. My phone is running stock ICS.
THe thing that bugs me most is that it doesn't prompt the network unlock screen, hence I can't enter my code.
The link you sent me apparently works for the att s2 sadly.

I wouldn't even waste my time with cellunlocker.net I bought an unlock code from them tried ALL the methods they gave you in the email and they didn't work I eventually took it to a cell repair guy locally and he unlocked it for me for 15 bucks and it was a factory unlock like it would be sim free
Galaxy SIII via XDA premium

I think I will root and put a rom only phone and try the unlock code again. Otherwise I am now having a paperweight.

What I meant was....in the app itself, AFTER I downloaded it from the Play Store, there is a tab to select the S3....inside the app. Did you actually download it and look at it? Just checking.

Doing a NAndroid and I am going to try this. What sucks is I don't know anyone with a micro sim from Tmobile here at work
EDIT
Didn't work, would not/could not save EFS folder from step 1.

I've run into the same issue here only I got my unlock code straight from ATT. SGSunlocker won't save the efs (even though it's in the save location it doesn't register as being saved) so it won't go to step 2. The unlock code entry sequence you mentioned doesn't work either (that's what ATT gave as well).
Haven't tried a tmobile sim yet though, just got the code yesterday.

Unlock your ATT phones?

No credit to me, . Was just browsing the international forums and came across this:
http://forum.xda-developers.com/showthread.php?t=2014982
Apparently it works for ATT folks, tried it on my rogers phone it didnt work. If it worked for anyone here please let me know. Also please thank the original threader if it worked.
EDIT: I think this works on rogers too. I forgot to INPUT THE * before the # , i didnt see that. ahaha.! Wow it cant be this easy!
2nd edit: confirmed working on rogers, telus, atnt, mobilicity, telus, bell

I just did it, will try and put in a different sim when I have a chance.

1- Before the procedure I installed an old inactive T-Mobile SIM card and was asked for an unlock code after the lock screen.
2- I powered down the phone, reinstalled my active AT&T SIM card and did all the steps mentioned in the other thread. First time I din't see one of the screens (the one prior to hitting back) so I did it a second time and all was according to the instructions.
3- I rebooted with the AT&T SIM card and then I shut the phone down again.
4- Inserted the same old inactive T-Mobile SIM card used on first test and I wasn't required to enter any code like it did before!
I cannot test any further because I don't have access to any other active SIM Card!
Lets wait and see if it was really that easy to unlock :highfive:

Did the steps on my Bell phone and put in a telus sim and it worked.

badass, worked on mine! (didn't check to see if it was already unlocked, though...)

This is really GREAT NEWS ...
Have anyone tried to see if it still works after the FACTORY RESET.

Worked for me. On Rogers

Did this last night, but I don't have another SIM card to try. Will test it out when i get to work.
edit... I can confirm that it did work on my AT&T i317.

Confirmed working for telus sgh-i317m.
Thanks! You deserve some credit coz I barely go through the international version thread and I would have never found this method if you didn't post it here. Of course the other guy gets a Thanks and a beer from me but you get a click on your Thanks button for reps!

I did it a couple of days ago. Tried it with my O2 pay-as-you-go SIM from the UK. The GN2 got a signal and connected to the network, so it does work. In the past, I got the screen asking for the unlock code.

Can someone try this link and tell me if it says unlocked?

I tried this on an AT&T Note 2 (SGH-I317) and it worked for me. I put a T-Mobile sim in it and it did not ask for an unlock code. Thank you guys!!!

That link seems to only check iPhones. I think the more important piece is that the phone accepts and works with non-AT&T SIMs. That pretty much means it's unlocked.

that's amazing it works for everyone !

Yep. Worked for my on my SGH-i317. I stuck in an inacitve Verizon SIM and no promoting for unlock.
So one thing I noticed is Settings -> About -> Status ... At the very bottom it says: Device Status: Modified. I never noticed this before ... Did that just appear? My phone is bone stock and has never been rooted or modified other than the unlock procedure.
Can someone else look at this before and after? I may go to the ATT store and unlock a display model to test...

Help. Emergency Calls Only

As title says my HOX is stuck at Emergency Calls Only. I'm on stock Rom with Unlocked Bootloader and root. Also, i have access to my contacts, numbers, IMEI, and data so I don't think is HW issue. I have replaced SIM card and problem is the same. Any help is welcome. Thanks in advance

Did you try a factory reset ?

You Mister, Should not buy stolen phones.

Yes I did a factory reset and the phone isn't a stolen one. It was a brand new phone.

Are you sure you are installing your sim card in the correct way, side?
Sorry for maybe stupid question, but sometimes it happenes.
Is your phone carrier locked? If it's and you are having same carrier sim card you should go to them and ask for help.
No problem that your boot is unlocked.

That's kinda weird....his imei would be blocked !
And as for the problem.....i would go to the shop where it came from. If you tried a factory reset and it is on stock software.....not much we can do about that. If its not working on stock software i don't think a custom rom will save you
Did you try your SIM with another phone / hox ?

If I try the SIM card on another phone it works. All problems came since I updated to JB. I was on a custom ICS, the relocked and OTA, reunlocked for root and recovery and 3 days later problems started.

You might want to take it back. If you have warranty.

[Q] No sim card inserted problem

Hi everyone!
I just got a T-mobile sgh-m919 from USA.
But when i tried to insert my own local sim card (not t-mobile and not american also) , the device just can't able to read the sim itself.
It doesn't give me some code to insert and things like that and i also tried to follow a orders to unlock or something like that but its still wont work.
I know that the problem is not at the sim utself because I got also google edition device that works with this sim normally.
I dont have a problem to install rom and root my phone if needed and also if i have to pay few dollars to open it is cool but i really have no idea what sould i do...
so if anyone knows... please let me know!
Thanks! :laugh::laugh:

Make sure the sim card slot is clean, and is the sim an original micro or a cut micro?

There is a way to bypass it as long as the device never took the 4.4.2 official update.. Do a little search in the general or development forum and you will find your answer! Its an app called region unlock

I did it! it just needed to change from LTE to GSM
But .. the error of the unknown sim still there... what can I do?
and i read a little bit here and saw that i can't install custom roms on this device with CWM (I got the mk2 build)
so.. this safestrap is the only way? kind of scary yo me.. not as simple as other phones.....
And anothe Q... in the T-mobile device, ( android 4.2.2) I dont have those problems? in this device i can install CWM? I'm already got root on this device but it didn't install the CWM i think...
Thanks!!!

Is the network on the Verizon phone set to global? If so and you're using an original micro sim then you might have better luck in the Verizon forums.. As for the T-Mobile device, yes you can install custom recovery, it's not locked down like the Verizon model

H815 can't make / receive calls but sms / data works great?

It's a UK vodafone G4 which I got unlocked and was using my O2 sim without issues. I ported the O2 number to iD Mobile (three network) and can use SMS as well as mobile data but calling doesn't work at all.
I put a Three sim in and it's exactly the same issue. The iD sim works fine in other phones. Other sim cards work fine in the G4. It's just iD and Three sims that won't make or receive calls.
I since used LGUP to install a kdz file (V20c-234-15) in the hope anything vodafone will be removed but that didn't make any difference. In the phone Settings if I check Network Status it shows the iD connections, in Status it shows Unknown Phone Number, in Network Mode it displays 2G/3G/4G, APN shows all correct iD settings. If I search for Available Networks it displays all the usual UK networks and only lets me select iD network.
Customer service said wait a few more days after porting and suggested a faulty sim (yet works in other phones) but after both iD and Three sims showing the same issue I've not much hope in their suggestions.
I know others that bought the vodafone G4 and unlocked it for Three haven't had any issues. I only found 1 other post online that has the exact same issue as me but their post hasn't updated since last month.
I don't know what to try. Other sims work, just not iD/Three. Any ideas for me to try?

I've since tried another kdz file for lollipop as I know for sure the sim worked before the number was ported before the phone was upgraded to MM.
Still doesn't work for calls, only data and SMS.
Can anyone offer more suggestions to try?

This is a weird problem maybe your problem is modem or wrong kdz file. Downlaod right file and flash again and be sure that you click refrush that is makes wipe in LGUP.(I use LGUP)

Thanks,
I had this problem with stock rom too though. I only started trying more kdz files in the hope that might work. Issue started the moment my number ported from O2 to iD Mobile.
Wierdly the phone doesn't like Three network sims either now and those worked fine before the number port happened.
Am really confused
