Nothing bad about this network but the major disadvantage is that it does not provide us with a good internet connection.
The 2g connection is itself very slow and yet in order to upgrade it does not provide with a 3g connection in Mumbai and also in most of the major cities.
The services are cheap but yet an internet connection without a 3g network for today’s generation is like a cell without a Bluetooth. If u are a constant user than you cannot go for this network.
