I bought this sim airtel in 2009 nice working well. airtel is the no. 1 mobile operator in india with its huge number of customers and help easly. its service is also great and the recharge plans are pretty good. 100/100 rs 150/150 nice offers.
The first thing I experienced that the network comverage you can find full network even in under water. use internet and message packs and so please use the airtel sim to get great network. In india 90% place you can touch in airtel. so nice of u
