[Resolved]  Tata Docomo — Tata docomo getting automatically disconnected every 15-30 secs

Address:

Bangalore, Karnataka

Hello,
My Tatadocomo 3g was working fine once i bought it from a local retailer nearby my place, but from past 2 months i have encountered a serious problem that it gets disconnected automatically every 30sec-1min due to which i am unable to download anything nor watch any movie, i cannot even login to my facebook account for more than 20secs.I tried to reach out to the customer care at 121 several times but they never reverted back with the correct solution to my problem, I recently visited to the retailer & he advised that its some technical problem from the networking company's end.one thing i understood is that these guys are frauds & ive decided to never go with any of their products again.Can somone please help fix this.
Thank you.
