Aircel is my first Sim card ever which I buyed when I got my first phone and that sim I’m using still now it’s been 5 years and I don’t want to leave this sim, the Costomer service is good they will respond you very fast when you compare with other operators the offers are great when I bought this It was giving Internet at very cheap prices even today the data plans are affordable in this operator and the voice plan you will have some amazing voice offers for Aircel to Aircel, yeah there are some negative things also the network is not that great you will not have network if you go some village side and this sim card still don have 4G, it still works only 2G & 3G which is not that great in todays time.
