http://androidforums.com – QUESTION: Given a valid 8-digit unlock code, what is the procedure to unlock the T-Mobile pay-as-you-go ZTE Concord cellphone? I've had a pay-as-you-go T-Mobile ZTE Concord, bought at Target, on a T-Mobile contract plan for months. I contacted T-Mobile 3 weeks ago and they finally sent me the 8-digit unlock code. But T-Mobile support had me type 3 different procedures to unlock, all of which failed. Since the phone can be bricked if we do this wrong too many times, I ask here: Q: What is the unlock procedure for the ZTE Concord given I have the IMEI and the 8-digit unlock code, and a 2-yea (General)

Hello Everyone!

I am new here just moved from the world of IOS. So I purchased a T-Mobile S4 full retail price. I was hoping to unlock it but they want me to wait 40 days before they give me the unlock code.

I havent been able to find any source for an unlock code.

Sorry if this is a repeat from anyone else's posts, i searched hard for this answer with no luck.

So i need to unlock my Lg connect ms840 to use on a different network (any other network) because i moved to a non metro pcs area.

i went to tmobile and got a new account, ported phone number over, swapped sim cards and nothing.. phone wont accept sim card, says not valid.

I received an unlock code from AT&T for my One XL. The unlock code comes up as unsuccessful. I followed the unlock instructions exactly. And I've called back and verified that AT&T has the correct IMEI and double checked the unlock code. I've never had an issue unlocking a phone before.

I contacted HTC.

I got a sim unlock code from AT&T today.

I took out at&t sim card and put in a t-mobile sim into lumia 900. It prompted me for PIN(unlock code). I keyed in unlock code for 10 times and the screen start to ask me for PUK. I entered the unlock code for couple more times and it still refused to unlock.

Then, I kept on trying until I hit 32 time.

HELP! I recently switched from AT&T to T-Mobile. I brought a SIM unlock code from cellunlocker.net to use with my HOX. It wasn’t my first time dealing with them - they have a good service over there. When I put the T-Mobile SIM card into my AT&T HTC One X (Rooted, Unlocked Bootloader, S-Off & Super CID). I didn’t get the prompt asking for the unlock code.

I found this great website that provides you with a free sim unlock code and all you have to do is complete one offer. The whole process took me about 20 min, and now my Verizon dinc2 works on t-mobile. the website is freeunlocks.com.

Have a T Mobile P500 running Android 2.3.5, Cyanogenmod 7.1.0-RC1 want to unlock using code 2954#*500# to access the PIN unlock screen and input my code but this doesn't come up.

"theunlock.ca" informed me that problem is with cyanogenmod, so do I need to restore root ROM first, unlock, then reinstall mod, or is there another way to unlock this phone with the code I got?

p.s.
