Airtel is the best mobile network provider with best realibility but what I didn’t like about it is that it is not so affordable.
I love internet serffing but airtel net pack are too costly , it 4g service provide very high speed but its not affordable.
Reliance’s 4g is one more step ahead from airtel as it also provide calling on 4g that is VOLTE ( Voive over long term evolution) this is really a new concept for indians, I wish airtel reduce the price of its internet packs , then I will be a fan of airtel.
