To convert postpaid to prepaid mobile connection before 90 days


I want to convert my postpaid mobile connection to prepaid. According to Airtel store guys, I should use this connection for at least 90 days before migrating from postpaid to prepaid. This is as per TRAI’s regulations and guidelines, they said.
I fail to understand that prepaid mobile connection can be converted to postpaid within 1-2 hours the same day when your prepaid mobile service gets activated, but for postpaid, we have to wait for 90 days?
If this is true, then according to Airtel and Vodafone Idea, Jio violates TRAI’s regulations and guidelines. Jio converts prepaid to postpaid and vice-versa within 90 days.
Kindly advise me on this.


You need not wait for 90 days. It can be converted from pre to post and vice versa whenever a subscriber wants.
