I had used Airtel 4G hotspot for 4 months. It was quite good in City areas than in rural areas. It was completely not reachable even if it is reachable in some areas data will work on 2G which is very slow. It can’t even load any website . Data will finish off so fast. Airtel Network provider is costliest comparing to other network providers. Personally I will not suggest this. Not worthy.
