sim card works which is what counts lol

ie cost me $25 for a free sim card because it wasn't included in my order as it was supposed to be

Att said Sim was invalid

THE AT&T MICO - SIM WORK GREAT

I ordered this Micro SIM, and it worked just fine.

I recieved this sim card free along with my purchase of the At&t Blackberry Z10

This Micro Sim is good,especially since phones start getting thin and thinner
