I am using idea in last 2 years.idea provide big network coverage.no network problem with this network.it also provide 4g internet service in punjab in kast 2 weeks.
I swapped my sim and upgrade to 4g connectivity.4g internet speed work very well in my phone.only one thing which I dont like in this network like charges ide service is very expensive call rates are very high and internet pack rates are also high.otherwise idea is good.
