Ive been using this Aircel Sim for quite a long time now, It was working good and was quite affordable for me before but now all of a sudden it makes me to advice people to not go for it, and the reason is quite simple that the network range is not quite good now, it just disappears all of a sudden and says "No Service" which quite irritates me. It may give me network range when I am in urban areas but it sucks when I travel cause most of the times I dont get any network bars. You may experience a sudden call drop too.
Ive had many issues with their customer service and support too cause I never got a perfect solution for my problems.
Charges are quite affordable for their plans but I am gonna switch to another network.
