I have bought airtel six month advance rentel plan ([protected])with free device 15days before... From the first day itself its not working properly, its very unstable... In my mobile also i am using airtel only and i am getting 4G network regularly so only i choose Airtel instead of Bsnl broadband... But this hotspot device is not working properly... I don't know what's the problem the device or simcard.. After purchasing the device i can't able to contact the dealer also... The person from customer care service centre asking to contact the dealer to solve the problem... I don't know what to do... Help us solve the problem... Thank in advance...
