I am from Chennai / Tamil Nadu. My mobile carreer is Airtel.
Earlier the cost was too high. Now the cost has come down due to Jio's wave.
My plan is Infinity 499. It has free incoming and outgoing calls, 100 SMS free. The plan is good.
Network coverage is good. Could be improved a lot.
Data limit is normally 3GB. Since, I use 4G phone, I get 3GB extra. Data limit is good.
Data speed is OK. But, many times when in need, it really does not work faster.
Customer service - Is ok. Have to watch the bills clearly and take necessary actions. It is very tiresome to reach the customer care guys. Sometimes, feel like switching the career.
All players are equally competitive. To make sure that they are the best, they have to provide timely benefits to the customers.
Thanks to the mobile portability. My view on Airtel is 75/100.
