Dear sir
I have been using Airtel service for a long time Now I want to switch over to Jio so I have tried to message 1900 for portability of my mobile connection keeping my number intact but everytime it shows failure of message. In fact when i sent message to a vodafone number from my airtel number the message was successfully sent. So I request you to Kindly enable me to port my Airtel number to JIO
