I would like to share my experience with Idea.I have been using Idea for more then 3 years now and I am more then happy with its service.
The network coverage of idea is pretty good I always have got full network all the time also the voice clarity of the network is also pretty good . speaking about the call rates it is very convenient.The 3g and 2g speed is also pretty good and fast.
The customer care service is also good they always pick up the call as well as solve the problem all the time.So if your looking for a mobile operator that is convenient as well as fitting to the budget then this is surly the one you are looking for an I can assure you that you will like the service of this operator and will never be disappointed.
