I had just used idea around 2 month after that I used to stop using this service because, this is the worst service.
Although it has largest network in interior places in uttarakhand there was many wars thing about idea.
First of all if you recharge on any current plan when your first plan will be expire and second plan will be valid two different plan we cant use on idea.
And second worst think is you can only use 4G network on 4G phone if you are using 4G idea SIM on 4G phone then you cant able to use three g network in that one while we can able to use 2G 3G and 4G network on 4G handset in Airtel and and some other operator.
Use idea when you are in jungle and you have a only idea services there but I think now a days jio is spreading their network around everywhere and I must say idea will be finish till next 2 years this is my genuine review I experience all this thing in just 2 month when I was using idea I am not say that I am hundred percent right but I share what I had face.
