I use aircel services two months, then I really get that there is very bad network range coverage.
I never get full tower range in my mobile, even many place there is very low signal, I frustate from aircel and I decided to switch another company for better signal quality.
even data signal is also not good, I was pay 3g cost of data but I get less than 2g speed od data, its waste of time and waste of money with this company.
hence as per my opinion please try another company of telecom.
