[Resolved]  Airtel — sim card not ported

Address:

445001

I got a message telling me that my sim card was activated after porting it from tata docomo to airtel, but it's been three days and the sim hasn't started working. Neither has the old sim stopped. It shows sim 4 not provisioned. When the message regarding the sim card set appeared, the airtel sim was briefly active. But it told me to restart the device, and when i did, the sim wasn't working.
