From the evening of 10/10/2016, i am facing network issue in my sim. Its showing emergency calls only. No network is there in the phone. For this i contacted two times to customer support. First they said the server is down, you can get back the signals within 1 hour, but till next i didn't get any signals.
Secondly when i again call them they said, might be there are some scratch on the sim, but there are scratch and all, so he took my complaint and said that u get the signals within 2hours. But till now i didn't get any signals
