I want to unlock my Nokia 5200 but i have to put £30 or more credit on my sim before Virgin will give me the code to unlock the phone. They tell me its free, but why £30 or more? Do they take that amount off your account or do you just have to put it on so they can see that you have done that when they look at your account in otherwords can you put it on and use it and still get the unlock code?
