Ok, I'm going to let you guys in on a secret...shhh..don't tell anyone, but I'm not as technically advanced as I probably should be in this day and age. So here's my question. I have a Galaxy S3 that I no longer use that was used with Straight Talk. Can I get a sim card in Jamaica and then use this phone there? I need to have a phone(aging parents), but if I don't have to buy one, that would be great. Any advise from you board techies?
