When teleor service introduced, with a low tariff rate all people are interested to be a part of telenor. But shortly all realize that it has a network problem, as they have great plans but no use of it as they having worst network.
As other service provider their customer support is also a headache, you cant reach the customer care executive with lots of try.
Telenor service is only useful in metro cities, at only there network is available, but in villages and remote areas telenor is not useful.
Considering charges it is very cheap, and have lots of reasonable plans, you can go with.
But all comes at point when their is no network, then what is use of such plans.
