Airtel — airtel 4g hotspot is connected but no internet access

Address:

Pune, Maharashtra, 411013

Me and my all team mates bought airtel 4g hotspot and its working fine before 14th september. Suddenly all o[censored]s airtel 4g hotspot connection is stop working. I called to airtel customer care but they said may be it is device issue or sim issue or may be network issue in my area. But fact is we all staying in different place in pune and we all having a same issue. It means its not a device issue or area issue. We can see our sim is in active status but we are not getting internet. Our sim is post paid one and we all paid it on timely manner.

Kindly help us to resolve the issue.
