Not sure what forum this belongs under: I am working in China and I have a Droid 3 I would like to put my China Mobile sim card in this phone and use the same phone when I travel back and forth. I am not tech savvy when it come to these phones. I heard you can call Verizon and they will give you some kind of code. What is the best way to go about this? I have put the China mobile sim card in this phone and it did asked for a code to unlock the phone. One of the tech people put a code in and it worked but was still using my states phone number. Then I turned the phone off and on and the China mobile card did not work after that.
