Bought a new Verizon droid mini for my son for college from Ebay. Supposed to be brand new, never used. Looked fine out of the box. I know nothing about anything tech-y so we're in big trouble here. Took it to both a Radio Shack and a Verizon dealer and they couldn't get the phone to work. They put the sim card in and they both got an error message that said that something was not compatible with the device? (They never shared, I could only read that much on the screen). Now I don't know what to do. All we wanted was a pay as you go plan, the cheapest one out there, for him for college and now we're told the phone is probably no good? I read somewhere that others tried other brand sim cards and they worked. Is that a possible solution? Any ideas?? Please help!!!
