THIS APP IS FOR THOSE DEVICES IN WHICH THERE IS ONLY LTE DATA ONLY NOT FOR CALLING OVER LTE.
THIS IS USEFULL APP BUT IN THIS APP THERE IS SO MANY ISSUES.
FIRST YOU HAVE TO OPEN THE DATA AND WAIT FOR CONNECTING IT WITH YOUR DATA, SO THIS IS TIME WASTING WHILE CALLING SOME ONE.
WHEN IT SHOWS ONLINE YOU CAN CALL WITH YOUR 4G SIM.
WHILE YOU ARE CALLING WITH SOMEONE USING THIS APP AND THAT TIME IF SOMEONE CALL YOU IN YOUR SECOND SIM THEN THE CALL WHICH IS MAKE BY JIO SIM IS HOLD AND NEW CALL YOU WILL SEE.
AND EVERY TIME YOU HAVE TO OPEN THE DATA AND MAKE JIO4GVOICE TO ONLINE.
BUT THEN ITS FINISH THE BATTERY BACKUP.
