Airtel, no doubt it gives you the best network, but its cost is really very high.
I am using this network currenly.
The rate cutter is 2 paise per second.
That means when I speak for 2 mins, i.e. 120 second, it costs me around 2 Rs and 40 paise ( 2.40 Rs) .
Internet cost is very very high.
3G cost is very high and that too very less fup.
Talktime is same as other operator, but the rate cutter is worst in comparison of other networks.
And the very bad habbit of airtel is, on the day of festival, even if you have an offer in your sim, it wont work on specific festivals, becaus airtel knows you will definately call someone inorder to wish people, so they increase the rate cutter, sms charges etc. Airtel is very cheap. It always look for their benefits not about the customers.
NOTE - If you don’t mind with money, and you need the best network. Then buy airtel. It is best.
If money matters you more then network then please dont buy this.
