[Resolved]  Airtel — DATA CARD - SIM FAILURE

Address: Tamil Nadu

I bought Airtel 3G Data card. It worked for a week. unexpectedly it displayed SIM CARD REGISTRATION FAILED. I contacted customer care, local distributor, Local AIRTEL SHOW room. They are not able to resolve the issue. My device and Sim are new. They dont have my detail at all.
When I visited air tel Show room, people response is also bad. More over there were 3 people shouting with the Manager for different issues.

DON'T GO FOR AIRTEL PRODUCTs
