Idea has best coverage and good service provider I am using Idea from last 12 year and found no complain against them and also best Net server and on roaming it is good and call does not drop and without any hazard it is the best one so any one can buy Idea connection without any discussion and enjoy the service. Net pack are also good and no breakage. Customer service is also very good they listen and clear all your doughts if you have any.
