Im an airtel customer. Im in the kerala circle. My local network coverage is under 'VALAKKADU' tower (in trivandrum district) situated hardly 2kms away from my home. But the status of airtel coverage on my mobile is very poor that i misses many important calls. I experience disturbance while calls. Whereas other networks offers full coverage there. I have been Airtel customer for the past 6 years. Hope they will read this this and multiply the signal strength under this tower i mentioned.
