Airtel is the no.1 service provider in karnataka. It has good signal strength and awesome offers in it. Im using this service from last 4 years because of this good signal strength. Whenever where ever u go signal will not gone. And internet speed also good in airtel. 3G service is mind blowing. but the current data pack rate is too high. Airtel have to decrease the airtel data pack rate.
Thats all. Finally airtel is the best best best.
