Hi friends
Today in India Airtel is a good network
because in any where in India the network coverage are very good .
it is full signal present any time any where in India and when I call any number than it is instantly connect to the number in only one attempt of calling and during calling no any disturbances are taken place .so it is a good network in India
but the call rate also more than all other netwo rk .
rate cutter power are also more than other network so it is only useful for incoming calling and we should keep an other sim card for outgoing calling.
