I recently ported my mobile no from Airtel to reliance gsm bcoz reliance was offering some great plan. But this is the mistake I made. Call quality is worst.
Call drops very often and 3g service is available only in certain areas of the city.
Most of the times 2g signals are their and if you move to the outskirts of the city you will not receive 2g signal. Moreover they claim to have fastest internet speeds but I wo der where on this earth they provide the speed which they claim to be. I am just waiting for my lock in period of 3 months and then again will switch to Airtel.
