Not sure if this is the correct forum for this. Have a droid. But am traveling to europe lots. Would like to have a phone that I can just put a pre paid sim card in. Must be a GSM quad band phone, and I need to have it unlocked to take a pre paid sim card. Am only used to VZW as that is what I have had. Would the google phone do this, or can I unlock a TMO phone. If so, how do I do this. Also, would it be able to get data as well as voice if I purchased a sim with those capabilities. Also, I figure if I have an ulocked phone, I can just get pay as you go sim cards here from TMO and ATT. Would these work as well? Thanks.
