    I have HTC desire816 , virgin mobile USA, we ask virgin mobile for unlock code, they reject it,
    Can you help for what can I do now,,

      VM USA sucks compared to VM in other regions. I have the same phone which I wanted to use on a trip to UK. They don’t allow it. Even though I paid $200 for the phone with no contract. ITS MY DAMN PHONE, I OWN IT, I should be allowed to do whatever the hell i want with it. VM UK however does just the opposite, much more accomodating than the backward 19th century VM USA

    Hi everyone, I found the guide on this website: better. I unlocked my phone quickly and its free. just follow the guide it’s really easy 🙂

    Virgin Mobile PROVIDED me with the unlock code for the desire 816. I have the code for them. Virgin Mobile Canada is ok with the phone problem is as below the phone is NOT asking for the unlock code. As with Jonathan and the others I am in the same boat, I have the activated new sim from Virgin Mobile Canada (USA and Canda totally separate company). I bought from USA. HOW DO YOU GET IT TO ASK FOR UNLOCK CODE??? As of Feb 2015 Virgin movile USA does give the unlock code. It is in the phone/program that is the problem
