Hey people I have been using airtel for nearly 6 years the service is absolutely amazing. The network is fantastic and the speed of mobile data is pretty good compared to the other networks. Even if I go to my village the connectivity issues excellent. The offers are also attractive and quite cheap
I am currently using 448rs booster pack, it comes with 82 days validity unlimited national and local calls with 1 gb data per day and 100 SMS per day free. I previously used 549 pack which provided the same benefits but with 2.5 GB per da with 30 days validity.All my family members are using airtel. Its a really good network any problem then you can contact the customer service 121 at any time and they will clear all Your queries. I am not sure about post paid but prepaid service is very good and affordable.
