Am using Airtel 4G 10gb plan from one month not so appreciable there is no difference between 3G & 4& and the speed is too slow, we cannot download any files It shows no signal while bad weather. I get the same speed with low charge in other network, they are giving 2G or 3G network in 4G connection and no proper coverage and my 10gb got over with 20 days and when I called to customer care there was no proper response and transparency.
Don’t waste your money for purchasing this devise, completely useless.
