Since last five year I have use AIRTEL prepaid sim. It was good network at very rare place. It have good talktime plan and it have good INTERNET SPEED. It 2G also work like 3G and its 4G network and internet is best. Me and my all family were used the airtel. Its best thing to its network quality. And its coustmer care have good responce to solve problem. It give best offer to every customer for Internet and talktime. It have good family plan which was connect 5 number which have very less call rate. I have only one isse to its 3G plans are so costly compare to other. But overall its service was good.
