Airtel is known as fasteat internet from all operator. Now a days airtel launched his cheapest and best plan for giving a powerful competion from jio, bsnl, Vodafone etc. Airtel has over 307 million customers across its operations at the end of November 2014. I will really recommended for you to buy airtel operation not jio servoce because jio is sill doing a bad network coverage and spedd. I always prescribe you to buy airtel 4g and buy a plan of 399 rs plan and enjoy fastest network
