It has been 7 months that im using airtel postpaid service but I am sorry to say that it is terrible for me now to keep it for long and I am looking for other mobile operator. I think instead of just marketing 4G network and increasing their subscribers they should work ob their service.
4G network on its own is a fast network you cant compare a xii grade child with a vi grade child if you really want to see benchmarks compare your 3G network with other 3G networks provided by other mobile operators or 2G network speed with them.
Being a techy I always appreciate new things as 4G by you but not at the cost of basic things.
