Having problems with BSNL SIM not functioning on your Moto G2 smartphone? Let our experts help you to resolve the problem quickly.

I am using Moto G2 mobile having dual SIM facility. I have 2 SIMs, BSNL & TATA DOCOMO. The Docomo is working in both port 1 & Port2 but BSNL SIM is not working in any of the ports. Why is it so?
