Help! Entering TMO USA TP2 SIM Unlock code, where do I enter it?

Guys I'm over in Europe and attempting to use a vodaphone SIM, I'm running NRG's ROM and radio 4.49.25.17.
T-Mobile had kindly provided the SIM unlock code for my TP2 prior to my trip but when I put in the Vodaphone SIM it doesn't prompt me for an unlock code?
Do I need to manually enter it somewhere?

I think its supposed to prompt you with a screen asking for the code, make sure the Vodafone sim is properly inserted and if that doesn't work you can try looking up the phones engineering mode.

Is the device booting into Windows Mobile & usable with the other SIM card installed? Where did you buy it? Sounds like it may be unlocked already. Anytime I put the wrong SIM in a locked device, on boot up I would get a message for the unlock code & device was unusable, would not progress past this screen. You had to either enter the unlock code or reset & remove the SIM card.

First, check if your device is unlocked by going to Start>Settings>System>Device Info and on one of the tabs, it should say unlocked somewhere. Or, you can check it by downloading ATCommander onto your device and entering [email protected]?40 into ATCommander. It should return 0 if you're unlocked. If it returns 1, you're SIM locked.
Now, if you are still locked, try flashing the Stock Tmobile USA ROM, and insert the Vodafone SIM then. Hopefully, a dialog should come up with an area to enter you unlock code. On the Kaiser, you supposedly had to be running the stock AT&T ROM in order to get the dialog unlock the device with an unlock code. Hopefully that will work. If not, TMobile tech support could probably answer this. Hope that helps

ooops

have just flashed a new rom that came with a radio change and like others i now have the sim lock crap..
i have ordered a sim unlock code and waiting for it..
once i have this code and unlocked my phone will i be able to swap radios as and when and never encounter this issue again?
also would changing the radio back to what i had fix it with out the unlock code?

Yes, after unlocking your phone, it's unlocked.
You may change radios as many and often you like

Carrier Sim Unlock Code Question.

Hi all new to the GNex.
I recently updated to IMM76I (Yakju) Please correct if I am wrong via OTA. However I am still locked to O2 UK. I hope to get my unlock code in the next few days from O2. I have one question.
Once I unlock my phone so it becomes sim free and then decide to go custom rom route, will I have to unlock the sim unlock again?
After reading threads about doing manual unlocking of the network lock. I was not sure if the scenario outlined in those threads about having to unlock sim after each reset will affect me in the same way.
Many Thanks
Tom

Question about Network Unlock

Hello all,
I have a Samsung Galaxy S III from AT&T.
I plan on traveling so, I wanted to unlock it. I followed the steps on Android 4.1.1 I believe and it seemed to work (my menus looked identical to the tutorial I followed, but I don't have another SIM to test with). But, I have had the phone for a while and it is really sluggish, so I backed it up and decided to do a hard reset. The phone is running much smoother now, but I did do an AT&T software update which brought it to Android 4.3, and now when I look at the menu after typing *#197328640# and following the steps, when I get to Network Unlock, it looks different. Did the update relock my phone to the AT&T network. Is there a way to verify? Should I just hard reset again and stick with 4.1? Pleas let me know as soon as possible as I am traveling soon.
Thanks for all the help

If your phone was unlocked using any method, it should not relock. You can test it with a non att sim.

How do I test if I don't have access to a non ATT sim, I have one Korean SIM card, but I don't know how to test with it because it is not currently being serviced.

Put in the non-ATT sim, power up the phone. If it does not ask you to enter an network or carrier unlock code, the phone is unlocked.

it shows no signal, but does not ask me for a network or a code. So it should be fine right?

Requesting network unlock hang

Hi guys, I'm trying to network unlock my M8 to use in Germany. I've inserted the card and typed in the network unlock code that I bought. Unfortunately, it is hanging on "Requesting network unlock'
I have tried factory resetting the phone.
What can I do?
Thank you

Are you stock, which carrier?

AT&T Skydragon rom

Try stock rom if you can see if that helps. Do a backup of your current rom, flash stock then restore backup

I'd suggest go back to complete stock also.

thanks, going back to complete stock worked. However my SIM card is locked every time I turn on the phone.

What do you mean your SIM card is locked? Do you mean you have to enter a pin to unlock the screen?
