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???"

Where to input unlock code.

to my luck, i got the unlock code for my htc s621 but i don't know where to put it. can someone please help? i'd really appreciate it. does the unlock code mean i can upgrade to wm6 or i still have to do something else? please tell me the instructions to input unlock code. thanks in advance.
p.s: i tried putting 3 old fido sim's with no access, i still didn't get any unlock code prompt etc - it just booted up and had no network access, that's all - i can't wait to put the unlock code in. is it possible to input the unlock code using the original sim i.e. rogers (it's a roger's locked phone).

also if i have the unlock code, can i use DASHV2Unlock from imei-check and make my own UNL file by putting in the code in a text file and putting the UNL extension or can someone help me make a UNL file as i already have the code. please help, thanks - i'm going crazy trying to figure this out, i have the unlock code but i don't know how to unlock it even though i put different network sim's - no unlock code prompt. phone's locked to rogers.
ok, i tried the text unl file, doesn't work - can someone guide me as to how can i make the UNL file, please - thanks.

where did you get the unlock code? don't they provide instructions?
the only way to flash a different rom is to cid unlock through imei check. if you haven't done that then you need to.

i got the unlock code from a member that's on gsm forum and xda developers - his names tupisdin. he was nice enough to provide the code but unfortunately, he didn't give me the instructions and i didn't pay - he gave it to me for free and it worked for a member of gsm forum, i need help, though - i want to try the unlock code but i don't know how to - i tried putting different sim cards from a different carrier, no luck, no unlock code prompt. so i'm wondering if someone can help me.

please help?

I hate to say it but it sounds like you leg got pulled. unless that guy has the program to generate the unlock code from your specific IMEI (in which case you would have had to give him your IMEI, which is a big no no, and could cost you lots of $$) then the code he gave you is false.
to SIM unlock your 620/621 the code is derived and generated off of your specific IMEI, so a general code will not work.
also, to get the prompt to put in the code, put in a foreign SIM into your 621 and it will ask you to unlock. that is where you input the SIM unlock code.
best of luck and i hope it works, though bout 99.9% chance it won't.

i did give him my imei. so it's a code that's generated off my imei. i'll try and get a foreign sim card and see what happens. thanks bro.

If i were you i'd be a little bit worried. if someone has your IMEI they can clone your phone and rack up a HUGE phone bill which you will be required to pay.
concerning the foreign SIM, foreign in this sense doesn't mean overseas etc... as long as it's a SIM that's not of your carrier it will initiate the sim unlock.

Incorrect. you have mixed up IMSI with IMEI. IMSI is property of SIM card and that's what can be really misused for that very purpose you were reffering to.

oh, my bad. question then. Why is there such a ruckus with posting your IMEI online then? there's a ton of sites that will ban you if you do that.

Please tech my how to clone any gsm device... using IMEI.

SIM Unlock problem!

Hey guys,
I recently called T-Mobile and asked for an unlock code for my Dash, but when I received it I got my friends SIM card to try and it said the code was incorrect. I typed i *#06# on my phone and the IMEI matches the one I gave them, so does anyone know what the problem is? I recently installed Kavana's 6.1 ROM, so would that be a reason why? Thanks!

The 4-digit PIN code on a SIM card is something different to a SIM lock - which code are you talking about?

I'm talking about an 8-digit unlock code I got from T-Mobile. I borrowed my friend's SIM (which is a Cingular SIM) so I could test to see if the unlock code worked, but it didn't.

The unlock code sent from T-Mobile should've worked... The only thing I could recommend would be to double-check the code they sent you. Make sure it's the same one you're entering. You said that the IMEI that pulled up after entering *#06# is the same as the one you first gave them. That should eliminate the IMEI as a potential problem.

I ran into this when I unlocked mine... What I ended up doing was rebooting, entering in the code with My T-Mobile SIM in, then switching to an non T-Mobile SIM after the unlock to make sure it was unlocked.. it was.

How do you enter the unlock code while using the T-Mobile SIM??? I always knew the phone to need a SIM of a different carrier.

Yeah I wanna know that too... I really want this thing unlocked! I appreciate all the help.

I should have been more clear. Reboot the device with the other providers SIM, the simlock dialog should kickin, then before you enter in the code take that SIM out and put yours in, enter the code then switch the cards again.. Thats how I got mine to work.
I used a Nextel SIM if it matters.
I've also heard that there has been success with a program called DASHv2Unlock, it forces the device into the simunlock mode without a forgien SIM in it. I was going to hunt it down but my method ended up working in the end

I was trying to change the theme on my shadow to shadow sliding panels.zip.However was promoted to load celecmd on my storage card and run the cmd. I don't know how to proceed from there cos i am not familiar with the cmds.Pls can somebody help me with this thing by outlining the cmd on this postp.i will appreciate the efforts from some one.

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:

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

Unlocked HTC 10 that used to be on ATT, where do i put the unlock code?

AT&T has given me an unlock code to release the phone so i can use it on sprint. The instructions say that a prompt should appear when putting in the sim, but nothing has happened. I was wondering if there was a way to force the prompt so I can input the code.
I'm on ICE rom, could that be a reason why I'm not getting the prompt? Can I go to the AT&T store with the unlock code and have them sim unlock it?
thanks.

Are you sure the phone is locked to AT&T? You title says "Unlocked HTC 10....". Your device could already be unlocked. Also, which sim card are you inserting and expecting code prompt to appear?
This is how it is normally done:
Lets say your device is locked to AT&T at the moment. You have to put another carrier's sim card(T-Mobile for example), then the code prompt should appear on the screen asking for the code.

Att never carried this phone...so how could they give you an unlock code? None are simlocked to ATT.

The guy I originally bought the phone from purchased the phone from HTC.com, which he then activated on att. when I bought the phone from him and tried to activate it on sprint, sprint told me the phone was carrier locked to att and I would have to request for an unlock code.
my unlock release went through and they emailed me the code, but when I put in my sprint sim card that sprint sent to me, there is no prompt that appears where I can put the 8 digit unlock code.

yeah I didn't know they did simlock either but I guess when you use a phone on their network it does.
when I tried to activate on sprint they said I had to take care of the att lock first. I have the unlock code but no idea where to use it. do I need to do something through the dialer?

Put Sprint sim in the device boot it up... IF theres a lock on the sim slot, it should ask for an unlock code which is input through the dialer when prompted

If device was bought from htc.com, then it should be unlocked already. I believe the radio frequency in your phone may not be fully compatible with Sprint.
Just check HTC's website and you will see that they offer separate models for Verizon and Sprint. - http://www.htc.com/us/go/buy-htc-10/
For example I have a T-Mobile service, so I purchased an unlocked HTC 10 which is compatible with AT&T as well. If I would have another carrier, such as Verizon or Sprint, then I would choose accordingly.
