I am buying a new Incredible One, and want to keep my old Incredible 2 as a seldom used second phone, and for traveling. I will go through Verizon to get it unlocked. Do I remove the vodaphone/verizon sim card before I can unlock? Do I need a new sim card in the phone before I can get it unlocked, or can I get the unlock code and do that at a later time when I get a sim?. Can I get a US sim card and use it here, and then get an international card and put it in when I go abroad? Is there an international card that will also work here in the Us and Canada? I appreciate any answers.
