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?

foriegn sim doesnt prompt to enter unlock code
Hello,
I just got my unlock code from TMO today. I put in a ATT sim but it does not prompt me to enter the code just says "Searching..." but never finds the signal.
Any help is appreciated.
currently running WM6.5 ROM V6.30EN By Lovebabyjing Build 23017[12/09/09]
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!

Are you looking to SIM unlock your phone?

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:

Problem caused by myself

Hy All,
I'm from Romania but I bought a Fire phone 64 gb, locked on T-mobile Germany, not from Amazon but from a Telekom shop.
I take it because of good price and also to try and test if will work on Telekom Romania network...it desn't work... but i was also prepared to buy the unlocking network code, and also bought that trough a friend....also updated to OS 3.6.6
Meanwhile, when i was in stand by to receive the unlocking code I inserted a romanian carrier sim card...input pin....the phone request the unlocking code...inserted a couple of times the numbers wrong...after dismiss and played trough menus..camera....after i closed the phone in waiting the unlocking code.
The code was send it to me after paying to T-mobile Germany ....and very excited open the phone to insert the code.....but now the phone is requesting the PUK code, instead of network unlocking code....I input the PUK code from sim card...phone says "unable the unlock the PUK"....it is normal not to be able to unlock the PUK because is still locked on T-mobile....and I figured out when insert the network unlocking code wrong for couple of times, the phone will block permanentrly the sim card.
I made it a factory reset, but after insert other carrier sim card the phone still asking for the PUK code and is not able to unlock the sim by PUK.
I have the phone...the unlocking code....good sim card....but i cannot proceed to insert the unlocking code because i played and inserted wrong...i think i am the only stupid in world who made this
Someone can help me with a solution? some combination of buttons...some hide menu to enter and insert the unlocking code?
Maybe if I will buy a T-mobile Germany sim card with activated roaming....insert sim....enter the PUK code of that sim, phone will be able to unlock that PUK protection over the network, and after insert another carrier sim will be able to input the unlocking code?
Regards and hope someone can help.

same problem here
Please help us.

First remove the romanian sim card from the fire phone and insert it any other UNLOCKED phone than try the change the sim pin code with your sim puk numbers. After that remove the sim pin request from the simcard than put it on your fire phone and try to unlock process again.

Hy All,
Long silence..because of work.
So... i send it back to Germany to test the method who was adviced from Telekom call center...I have talked with the support team from Telekom Germany and it seems to solve the problem it is must to insert an plan (abonament) sim card ( not working with a pre pay sim card) from the network who is locked ...it doesn't matter of who have the plan sim...one of your friend or in a shop...and it must be insert the PUK code of that sim and it remove this locking and registering to theyr system, and after will be able to insert any sim card and insert the unlocking code...this is what they told me on the phone...
They have tried and inserted several times an abonament sim card....same problem...but i think they and also people from Telekom shops are out of this space with technics/phones.... all tell me not working...now wait to send in service...maybe they reinstall the software.
Someone tried the method described above by the user "ease_the_pain" or an hard reset (vol. up + vol. down + on/off button in the same time)?
Maybe a hard reset will make the phone to start from beginning with unlocking request... if someone will make the phone work after hard reset please leave message asap...i want to avoid to send the phone in service and tell to my friends to send back to me..
Thx and Regards

Solved
Problem solved...Phone replaced with a new one.... new unlock code now exploring phone and settings....and apps

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/unlock-bands-qualcomm-device-phone-t2880239
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

SIM Unlock Prompt

Hi,
I've bought a XT1952DL (DL stands for damn locked) in US and traveled back to Canada. When I insert a Sim card from different providers, it does recognize it (Network SIM lock message) but it won't prompt for an unlock code...
Any idea on how I can solve this issue?
Thank you!

Dl is for trackfone variant it's very hard get unlock code for them

Metro PCS is the worst I've ever dealt with.... You need 180 continuous days of service locked to that IMEI to be eligible for unlock... CRAZY!
Perhaps we can modem flash? How are the variants encoded? How can we convert?
So... I flashed the stock modem and everything else stock, now I get a SIM Unlock code entering box... but I can't find anything that can produce it, paid or otherwise :/. At least now I don't have any MetroPCS garbage on the phone.
https://forum.xda-developers.com/moto-g7/how-to/channel-moto-g7-factory-firmware-images-t3996303

Are you saying you flash the XT1952DL to Retail? If so, how!? This phone is a pain... I found a remote USB sim unlock for $30, but would like this thing on retail ROM :/
