a) people on pay-as-you-go after 12 months; or
people who have completed the minimum term of their contract
I bought my phone for ~£100 including the mandatory £10 credit with a £7 monthly contract with zero (0) month minimum term. Thus I immediately qualify for an unlock code. I called Virgin (789 from your Virgin SIM/mobile or 08001839146 from elsewhere (be advised that this is not free to call from most mobile networks but is free to call via Skype!) and asked for my unlock code. She took the last four digits and the CVS of my debit card to charge the £15.32 fee and the unlock code will arrive at the billing card address in 7-10 (working?) days.
I'm planning to use a TalkTalk SIM card (operating on the Vodaphone network) because existing TalkTalk customers can get twice as many minutes and data for £3.75 vs Virgin for £7! Bonus is that I can ring home from my mobile for free! No doubt the price will go up suddenly at the end of the 12 months but I'll set a Google Calendar reminder to prepare me
Edit: the smiley up there was meant to be a b followed by a bracket but a guy in shades works also.
