I had bought a sim card of idea cellular networks because of it’s low cost schemes, however was disappointed after receiving it.
The reason is because the coverage of it’s network is pathetic. Whenever I would be at home the network was never available. When I would receive calls, I would have to come near my window just to listen voice calls clearly. Was not with the customer care support as well, because most of the times it just kept ringing and no one attended my call. Not happy with idea mobile operator.
