I use idea network more than 5 years. The network speed is very slow. Some time do not open any apps. I complaint this problem. Idea showroom say that your phone is 3g, you can use 4g phone then you will get high network speed. Then my samsung s3 phone is exchanged. And I bring vivo v5s. And I recharged for 3 months. First month the internet speed is high, and then it reduced. Night time, the internet speed is very slow.
