I have use so many sim in my life. But sim is worst than all other. It’s network is so weak. And the speed of internet is very slow that I can’t explain. In my living area it show onle 3 line of network. When I go to my village it show just 1 line network. But some place I get full network. When I brows or play any online game it always bufring. I know won’t belive me. But if you buy this airtel sim you can see it your self.
