Airtel — sim card functionality

Address:

Chandigarh, Punjab

Hi, I am facing that my sim functionality is not working properly. I have notified that very frequent kg sim get disconnected on its own and phone start asking for reboot. At times, after reboot sim get enable and I can start using calling and SMS feature. But at times, even after restart it remains disable. I have to restart the phone manually many times and than only by hit and trial method sim start functioning. I have already tried by swapping the sim card on both slots. This does not seem to be slot issue. I have observed that this issue is there since the time you have changed my postpaid plan. I have asked the customer care person not to change my plan but after two days they have changed it. I have a phone recording of every call I have with airtel company. Even I got agree when they have changed my plan because the airtel person told me that they can not revert back to original plan. Now this issue start. Do you want me to register complaint with TRAI. I am not feeling frustrated at times.
