Sim Unlock - One (M8) Q&A, Help & Troubleshooting

Hi guys,
I'm trying to sim unlock my phone to use with a different sim card in Europe. Currently I have the AT&T version of the phone. I am S-Off and I have used SuperCID. Unfortunately, I tried on multiple sites to buy a code to unlock my phone (related to my IMEI number). However, every site keeps telling me that they cannot find a code for my device. I checked and my IMEI does not appear to be blacklisted. What can I do now?
Thanks,

Unlocking Dash via TmobileCustSvc

I called Tmo (USA) and told them that I was travelling to Canada and wanted my SIM unlock code for my Dash. I gave them my IMEI and they emailed me a 8 digit code to unlock the phone. Only problem is that I need the "foreign" SIM to initiate the code entry on the phone according to their instructions (see below). I am wondering if there is another way to do this without the "foreign" SIM because I want to unlock it prior to travelling in fear that I dont want to break/brick my Dash while travelling.
Here is their email to me:
T-Mobile Sim Unlock Request
Sim Unlock Reference: XXXXXXX
IMEI: XXXXXXXXXXXXXXXX
Unlock Code: XXXXXXXX
Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your HTC device.
1. Insert the foreign SIM card
2. Power on the device and the display should read "Please input unlock code"
3. Enter the unlock code and the device should display "Phone is unlocked."
4. Allow the phone to scan the network (or manually click on the antenna icon to do this)
It is very important that the instructions and SIM unlock code are entered correctly as listed. If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked. You will need to verify the IMEI by pressing *#06# and contact Customer Care for support.
I saw this file (DASHv2Unlock.zip) from here. Anyone know if the code I got from Tmo will work with the DASH2Unlock program?
Thanks!

Thanks, I try to go to a local Cingular retail store. MOst of my friends use Nextel or Sprint or Tmobile around here. Cingular has terrible coverage in Hawaii.
Sim
You shouldn't need a "foreign sim," but rather any sim that's not on your carrier, then the phone should give you the unlock code prompt. I always keep an old cingular sim around for this purpose.
^ Any SIM other than your carrier's SIM is a foreign one.
~Cheers~
Actually, to unlock the phones you do not even need a foreign sim. You can use your T-Mobile SIM. They just tell you that so you can make sure it's working

Thanks for the laugh
Yep, fairly easy. As soon a TMo emailed me my unlock code, I borrowed a coworker's cingular sim card and took all of 30 seconds total.

Could have taken 15 seconds if you didn't swap SIMs

How would you enter a code otherwise?When the Cingular sim was in it, it automatically prompted me for the unlock code.
Good question
im also curios as i dont have a foreign sim handy jsut been waiting for one to come my way to unlock.
When TMo unlocks??
When you have TMo unlock the phone for you is the SIM unlocked and the CID unlocked also? Or do I have to use the website everyone has mentioned to get both things unlocked?

Any help is appreciated.

tried to flash back to tmo official but kept getting errors at 3% of upgrade. "error 244 incorrect model id???"

Does HardSPL and flashing a new rom unlock the phone?

Forgive me, I couldnt find the answer to this question.
If it doesnt, what is the best way to do it!
Thanks!

Yes, sorry
There are various sites that will give you the unlock code which is based on your IMEI number, but you shoudl be able to contact the carrier that branded the device and ask them for the unlock code. Then just put the SIM card you want to use in the phone and turn it on, you will get a Network is locked message with a box for you to enter the unlock code you got from the branded carrier.

I havent been able to get an unlock code since the 90's - I use Tmobile and they wouldnt even consider doing it.
If you are unable to obtain the unlock code from T-Mobile then you may want to check this thread:

Htc One X sim unlock

Hi, I have a vodafone sim locked htc one x with stock android 4.2.2 with sense 5, bootloader locked, non rooted.
I think that it's locked to vodafone uk, but I'm not sure, currently I'm using it in Hungary with a vodafone hungary sim card.
The operator does not provide the sim unlock code for this phone.
I have purchased an online sim unlock code wich was unfortunately not accepted by the phone.
I have inserted a sim card from a different operator, entered the sim unlock code, but the code was not accepted.
I've got a refund for the non working code, but my problem still remains: I want to sim unlock my phone.
I have contacted several other companies that sell sim unlock codes, but they all provided me with that same code, and told me that it should work with stock android 4.1, wich I don't have and I don't want to unlock the bootloader, because I need the official warranty.
So, no code from the operator, provided code does not work, bootloader unlock is not an option.
What can I do to sim unlock my phone?
vodafone changes the sim unlock code, i've seen this on other htc phones, if you can't find a solution on xda, the codes bought from other sites will not work.

Sim Unlock Problem...

Daer Members...
I have 4 One X, which is sim locked. I obtained sim unlock code from my unlock reseller, which shows incorrect code in all the mobiles.
I tried changing more than 3 rom's with the same mobile cid for all the phones. After that also code is not working.
Also i tried another unlock reseller for code, but the code came was same as given by first unlocke reseller.
Is there any chance to read or find sim unlock code from mobile partition.
Actually in which partition the sim unlock code will be there.

Note:- All HOX are Generic, Endeavoru S-On, Not Carrier Branded like AT&T, Telstra, Rogers, CID is HTC__034...

Htc sprint prepaid unlock window

Hi,
Usually when we put a foreign sim card into a phone that is locked into a carrier, in my case sprint, the phone will ask me for a unlock code to put in. Strangely when I put another (bell Canada) sum into my new sprint prepaid phone it just remind me that the sim card is invalid but no pop up window to enter an unlock code. There is a website that will generate a unique config.dat based on imei serial and flash in hboot menu. This doesn't work unfortunately. I also paid sunshine to have s-off and changed my cid to the Super one 11111111, still not working.
Now I have sorta crazy idea. There are other variant of single sim roms that may be able to bring up the sim unlock code window but there is no way I can flash it since it always checks my darn model id and present a code 41 error in facebook. Is there anyway I can finally manage to enter an unlock code for my sim because I loved the phone so much.
Thanks!
I would like to do this as well with my Koodo Sim.
