My last phone was a Alcatel OneTouch on the Virgin Mobile network. When I got my Motorola Droid Razr M, I wanted to swap out the SIM cards. Both cards are the same size and when I put the SIM card in, it transfers the network information over, but I get an error telling me that my SIM card is from an unknown source. It tells me that the SIM card has been locked and to power cycle the device. Is there anyway to fix this?
