This is a great network which provide lot of offers(Kerala) . I am from the state kerala and it is the best network for a standard user.It provides lot of offers that other provides cannot . For example, Aircel provide us with 1Gb unlimited 3g for 125rs were other network provide 1Gb limited offer for 250rs. Did you notice that it is almost double the amount.That is the reason for me opting Aircel.
But Aircel is not suitable for travelers because it have only net work in Palakkad and Trivandrum district, so only choose this operator if are in any of these states.Aircel also gives extra offers on online recharge from their website.Now is the best time to take Aircel connection because it gives unlimited 2g internet for 1yearfor new connections, I think the speed is 64kbps(not sure).
They also give 3g offers 100mb data for each month for 12 months . It gives free income at roaming and out going at 1p/sec(5 state same rate).You get monthly offers at rs 15(100mb).If Aircel network overage was good then there will be no one to beat them.Their customer service is good.So I suggest Aircel for Kerala circle.
