Hi, I bought a cheap mobile just as a spare the other day hoping I could just put any sim into it but apparently not! It is a Virgin VM621i and I'm wanting to put a T-mobile sim into it, does anybody know what the code is to unlock it? I've tried pm 'spit roast' on another thread on here but he has not replied (as he can do it if you just pm him). Would be very grateful if someone could point me in the right direction? Thanks in advance, Paul.
