Idea Cellular — there is no network in my idea sim

Address:

Secunderabad, Hyderabad, Telangana

I stay in hyderabad, telangana. My sim is also not showing any network since many days. I tried every possible thing but then too no solution.

I have done a recharge also today thinking that there is some issue regarding validity but even after doing that the same issue persists.

Even calling customer care did not help. What to do?? Help me...
