[Q] How to sim-unlock orange uk mozart?

Hello,
It is my first post, I just bought my htc 7 mozart.
I want to unlock it, so i could use my polish carrier sim card (carrier name Play).
I have sim-unlock code that i got after giving my imei number.
My question is when do i write this sim-unlock code?
Many quides on net say that i should insert my sim card (not orange uk but polish play) and after switching on the phone will be displayed area for entering this code.
When i turn device on i get information that there is no sim or it is invalid and i have 2 options :
1 click 'emergency call' (in this area) i cant type my unlock code.
2 click 'close' and device continues booting and after few sec i get main wp7 screen.
So i'm not asked for my unlock code.
Where in this phone is place to type sim unlock code?
I've seen some people here unlocked their htc mozarts with code, could someone write please how it can be done?
I say once again it's locked on orange uk.
Sorry for my bad english.
Thanks in advance guys.
Will debranding/flashing help?
There must be an option to unlock it via code...
When i use my polish card or no card at all in mainscreen of wp7 i see a cell 'no sim' i click it and again emergency calls only.
Where to type this sim-unlock code?
When I unlocked my Orange UK phone, it asked for a pin when I inserted my O2 sim card. This was when I entered the unlock code and after that it's been fine.
I don't see why an overseas SIM would be different, but one way round this would be to buy a UK PAYG sim from eBay or similar, then use that to unlock, then use your sim after that?
IT'S DONE
I was inserting sim card wrong way, when i had put it properly i was asked for unlock code.

Hello,
I'm new in WP7, I just got an HTC 7 Mozart, locked to Swiss Orange. So I wonder if is possible to unlock for free, or is there any specific tool for that. Any help would be appreciated.

SIM UNLOCK issue

Here is my problem:
I am trying to use GoPhone SIM with my Atrix. When I put GoPhone SIM in Atrix it says Invalid SIM card (it should be noted that phone works with normal AT&T SIMs).
Solution attempt #1: I went ahead and ordered unlock code for Atrix on ebay. Got the code.
Put GoPhone SIM inside , dialed #073887* entered the code and failed in unlocking.
Solution attempt#2: I asked AT&T for an unlock code, they gave it to me in two weeks. Entered it ,failure again.
Could it be that my phone is very special Atrix that can not be unlocked even by AT&T?
PS
I also tried unlocking without SIM card, no luck. It says NETWORK UNLOCK REQUEST UNSUCCESSFUL
Take a look at my thread, essentially the same issue. Not certain you can even unlock the Atrix

[Q] HTC Desire 612 'non Verizon SIM' error

Am getting this error whenever I try to use a non Verizon SIM card
"non Verizon SIM: The SIM card is from an unknown source"
Verizon assured me the device was unlocked and ready for use with any carrier SIM and that should it demand an unlock code, I should enter 000000 or 123456. But i can't get past this screen.
Please assist.
