Can I make a video call if my data connection is turned off on Jio sim?
You can make a video call or switch from voice to video call even if your data connection is turned off on Jio SIM being used in a VoLTE device. For all LTE / 2G / 3G devices using JioCall App, the mobile data cannot be switched off as it will take the app offline resulting in unable to make or receive calls and send or receive SMS.
