I am currently using a aircel sim card, and I want to share my some of the bad experiences with aircel.first of all, the network of this company is very poor, no coverage in most of the places when you goes out of your city , then there is very less network coverage and it gives very poor voice call quality, customer service is also very bad as when you call them they dont even reply and even if you are lucky enough to get their reply then they never solves your issue and cut the line, only thing is their charges that I can say I am satisfied with just because their call rates are low. Overall the services are very poor dont go for aircel.!
