I am raviaknt nikale. Customer of airtel network. Facing problem of no network at my resident area in kalyan west near bhanusagar talkies, kalyan station area. And airtel network is always collapsed where ever the most places i visited. The range of network is so poor and it's too inconvenient, since i busy with blood arrangements types of social work it's become to irritating. Could not make any call at emergency basis. Please provide me a good solution.
