Aircel is one the badest network that I have ever used. Sim card is almost busy for 6 hours in telling no network available or emergency calls only.
Call rates are also very high, deducted unwanted balance from sim and when tries to call customer support than they are always busy.
Although net packs are little bit low in cost as compared to other network but that is the use of it when there is no network. My almost 400mb was wasted because of no network customer support is also bad they talk very rudely.
