Desperately need help

[JOSHPLONG]

So I bought an unlocked verizon blackberry tour from my friend a couple days ago and put in my att sim card. The first day it worked fine, but now it won't text, call or anything. If I try to call someone it tells me the phone is unauthorized or something and to call #8899 for help, but I'm pretty sure it won't work since I have no account with them. I am brand new to blackberries and I need help!

You need to see if the device has been blacklisted or reported lost or stolen.

Sounds like u might have been sold a dud aka a lost or stolen BlackBerry.
