Airtel is the number one mobile network provider in waste bangal. I am using the sim since I phone have.
I lived in kolkata and I can use 2g 3g and also 4g network network service is realy good its always high in kolkata and also good ruralar area and its surprising me that I get network on metro rail.
the net suffering is realy fast and the net pickup is alsoaffordable to all.
they give nice offer by missing and calling.
It is realy good service operater. you can use it.
