receive calls/txt messages.? I bought a used Verizon Motorola Q 9c off Craigslist and I activated it without buying a data package and it seemed to be working fine until I started receiving "login error" messages. Along with the login errors, I am unable to make phone calls or text messages without taking out the battery and restarting the phone and that went just as well with receiving calls or txts, this happens randomly at any given time. The only problems I can think of is that I either bought a broken phone or I need to have a data plan in order for the phone to work. Please Help! Thank You.

Everything else works fine. I have a family plan with unlimited txts and pixs, but have all data blocked and pix/flix messages as well.
