I am living in Delhi-NCR and usually travel to U.P but Never get the Aircel Network. Voice is always disconnected even I my phone shows the full network coverage.So voice service is useless at all.
Data services are also very irritating and slow. 2G services are very poor compared to other operators like Airtel, Vodafone. Aircel usually gives the 50 Mb promotional free data but I never become able to use it due to very poor data service so not usable for smart phones as well. Sending mails and downloading couldn’t be done on this network. So overall I wouldn’t advice to anyone to use this network.
