I'm part of a mission group that goes to Jamaica and I have received a request from an orphanage worker to bring a Razr V3 phone to replace his broken one. I found a seller with cheap used AT&T Razr V3 phones but I want to make sure they can work in Jamaica. From what I understand I need to get an unlock code and I see various options with a fairly wide range of prices. First off does it matter if its the $4 option or the $15 option? Will any of them work if I don't currently have any service on the phone? If I get it unlocked will it just work when I drop in a Digicel sim card with minutes once I'm in Jamaica? Thanks for your help!
