I have been using idea for 5 years.But the network coverage is totally worst by Idea.I live in a rural area.When I enter into my house the network of my phone disappeared fully.If someone try to call me when I am at home, the call can not connected.I am missing many important calls.Whenever I want to call someone then I have to come outside of home or have to go on terries.The voice clarity is also very very bad in idea network.And the internet is only good in cities.In rural area 2g is not working properly and 4g is not working atall.
