Hello, I have the pay-as-you-go Big Data and Texts plan. I assumed since there is no contract (I just refill my account online whenever balance goes low..), the phone is unlocked. However, now that I have moved out of the UK for the time being, I tried to put in a local sim card and it is not letting me do so. It is asking for a code to unlock the phone. Could you please let me know where I can find this code? It is extremely unfair of Virgin Mobile to keep my phone locked considering I never signed any time-bound contracts with you!
