I have converted my reliance number into idea postpaid before 4 months ago.
My plan is of 299Rs and after all taxes like GST etc bill amount come is 352Rs.
Unlimited call and daily 1GB data but idea network is poor as I didn't get stronger range in mobile and home.
I have to come outside to pick up the because of poor range.
Internet speed is not that much of good its like 2G-3G speed.
I faced lots of problems related to network range in Mumbai and village satara.
Some other network operator like jio provides same plan with nice service in only 150Rs per month.
Overall costly and bad network service provider.
