Have good coverage, but talking of its recent 3g plan slicing , the speed too little over 2g.
I cant get more then 90 kbps in full coverage even.u ll b confused over ur 3g connection even, I doubt it to b 2g.
Airtel has maintained 3g speed, with price they have kept their service up
Cant say how disgusting customer service are, the cc will keep u waiting for 10 minutes, instead of connecting to cc executive , ll disconnect you, voice quality is hard to catch on.
