Airtlel 4G is worst network as they are showing ads that you find network even on mountain but the truth is do not get speed even at prime locations in delhi NCR,
When call upon customer service they put my call on hold for more than 20 minutes and after that call gets disconnected itself.
Airtel is doing totally fake promotion.
I will not recommend any one for Airtel 4G.
It totally waste if you spend on airtel 4G.
2 G of other network is better than this.
