I’ve been using Aircel for some months and I have been so frustrated with that.
The internet speed is very slow and sometimes It doesn’t even work. However the internet charges are lower in compare to other networks.
I also sometimes have to face call drops. That may be due to poor network coverage. When we go to little towns or villages, Don’t surprise if there’s not even network of Aircel. Thats the worst thing happens with Aircel.
The roaming charges also exist. I prefer to use BSNL while roaming as It doesn’t charge for making calls and sms in roaming.
I don’t recommend you to have Aircel. It may be cheaper but it is kinda worst experience I have been with.
