did you try the unlock app? I guess there is a unlock app but I don't shure.
other way it`s buy a IMEI unlock code, I know that it works for your device, If ask for a code when you insert a non carrier SIM.
i have the same doubt, I get a galaxy s9 t- mobile. but the phone it`s unlocked, I don't know if the phone was unlocked by a unofficial way.

Go to the Samsung site and talk to the chat people. They'll give you a code. Have for me anyway.

No. To SIM unlock, you must either use this utility or get an unlock code based on your device's IMEI.
Just call AT&T they'll give it to you over the phone. I was going up to Canada for a week and got them to unlock my phone for me. Well to give me the unlock code. As soon as I was up there I put in the new sim card and punched in the code and it worked like a charm.

AT&T's policy is to provide the unlock code 90 days after the purchase date (although their website states after service has been active for 90 days).
nop they are diferent stuffs , one thing is change software and other unlock phone

[Q] Is the cell unlock code dependent on RUU/firmware?

I decided to upgrade to M9. I currently have a T-mobile M8, that I decided to give away to a friend, he does not use T-mobile or live in the US.
So the question is, if I flash a HTC unlocked edition RUU, will the Sim unlock code provided by T-mobile still work?
Just dropping by....

From what I know, no, it might not work because the phone might not even ask for the code.
In order to unlock the phone you have to insert a NON accepted sim and get it to prompt for the "SIM network unlock PIN".
If this is the situation, you can try flashing and see if it prompts for the code with your friends sim card.
IF, however, it does ask for the code, just try it first. If it doesn't work you have to flash back to stock Tmobile firmware, Unlock it, then it will work with you friend.
I recommend a few sites like cellphoneunlock.net or cellunlocker.net as I have had much success with them over the years. I don't know if you are using other sites but I am just contributing what I know so far
Good luck to you and your friend! :good:

Just make sure the ROM you are flashing supports official HTC codes, I think that is how it goes.
I can say that if you need codes use cellunlocker.net , they are pretty legit.

I´ve juste received the notice from cellunlocker that they cant get a code for my S6 Edge T-Mobile. They refunded me the money today.
A friend of mine managed to get a code from a different source, but the code is not working.
I am looking for another way to unlock it.
I ´ve seen nothing by software until today.
Hope you can find a way to unlock it. Please inform if you succeed. I'll do the same.

Those codes won't work (Not that they are wrong but because of the Tmobile Rom). I have been able to successful unlock the SM-920T by flashing the SM-G920T1 rom (Metro) but because the S6 edge is not released on Metro i am trying to find out an international rom that would work. I just tried the Tmobile Germany Rom and it failed.

Exactly, that is what I am waiting for , to finally be able to accomplish the unlock for g925t...
Just so you know, that once you unlock it, you cannot go back to the T-mobile rom, or your unlock will go back to failure....
Just wanted to let you know......
This method works for sure https://www.youtube.com/watch?v=TxOuHIUWAFk
I can do it for you and even support 5.1.1 . no rooting needed no teamviewer.
yes , via S3X box, its a way, flashing out a custom cert, i paid to theunlockpros ,25 bucks, in 10 minutes they do the magic remotely , im very happy , super fast
by any chance can you unlock the lg g4 model H811?
The most surefire way to get your unlock code is to finish paying for your phone. At least if you are in the US. It is the law. They have to give you the unlock code if you OWN the phone. If you are currently financing it then you have to try this way. But I warn you Triple warn even WARNING WARNING WARNING no mater what anyone says. unlocking your phone by these means will get you what you want but you will have boot problems later. Your EFS gets totally screwed from doing the remote unlock. Don't say I didn't warn you.
*EDIT*
Plus stealing is really bad karma anyway.

vouch for that guy!! he's unlock my phone, but you need to root your phone tho
there is a tmoblie app on the phone that lets you request an unlock. look in the tmoblie folder in the app drawer. After that, activate Dev options by hitting the build number and turn on OEM unlocking in the dev options
Did it work

Sprint HTC One M8 - with Sprint provided unlock code (6 digits)

I called and got my phone's unlock codes (domestic) however Sprint declined to provide how to unlock instructions. told me to go to my future carrier and give them the unlock code.
I called T-Mobile current provider and they told me... no Sprint can unlock and TMo, doesn't know how.
so I am stuck with legitimate Sprint unlock codes... and no idea how to use them.
Someone knows how this works here or it's better off just flash customs rom and unlock XDA way?
Thanks,
When you insert another carrier's SIM (in this case, T-Mob) it should ask for the code, then you just enter it.
Custom ROM isn't going to help you unlock the SIM, nor is there a working "hack" to do so without a code.
Thanks for your reply,
I've tried ATT, TMO sim and the phone does not ask for sim unlock code... it just says contact customer care.
or if someone knows how to get the phone to ask me for SIM/UICC unlock code... some hot keys to press, that can help too since I have the codes from Sprint.
**i am also reading about Sprint Sim unlock on One M8, so complicated!!!**
If you talking about the following mods, they are for unlocking the bands, which AFAIK is not the same as SIM (subsidy) unlock:

http://forum.xda-developers.com/htc-one-m8/general/how-to-convert-cdma-m8-sprint-vzw-gsm-t3303812
yeah, can't find a way to unlock sim to use w/ T-mo ATT. strange... I have the codes from Sprint and no one's done it? good thing I got HTC 10 factory unlocked this time no such problem later on

If the T-Mobile site says it's blocked, then it is blacklisted. Sorry, it won't work on any network. You need to call T-Mobile and ask why it's blocked.
And the only way to network unlock the T-Mobile S8/+ is with the T-Mobile unlock app. Flashing the unlocked firmware and then entering an unlock code won't work. T-Mobile has to be the one to unlock it, and it has to be initiated through the app.

Sorry but now TMB can be unlocked through reading codes no need for unlock app, plus if the imei is blacklisted @ TMB so it is blocked for TMB only which means if he use AT&T sim after unlock it will definitely work !!!

That's absolutely false. If it's blacklisted through T-Mo, it's blacklisted for all US carriers.
And what's your source saying you can use unlock codes on T-Mo? Because no one here has been able to do that. Many people have lost money buying useless codes for T-Mobile.
