I am a recent convert to the Droid Pro. Verizon has provided the unlock code for my phone. I have a few questions: 1. I will be traveling in the UK and then to Asia (e.g. Hong Kong, Singapore, Malaysia, Vietnam). Can anyone suggest good sources to purchase prepaid SIM cards that will work? 2. According to Verizon I won't be able to enter the code until I insert the SIM. Does this make sense to you all? 3. I am a little nervous about the unlock code they gave me (in fact, they gave me two different ones because they were not sure). Shouldn't they know what the exact unlock code is? I'm thinking I should call back and ask another rep. 4. Is there anything I can do to test the unlock code while still stateside?
