Hello guys, I have jio sim which VOWifi works on my excitel broadband but when i turn off airplane mode VOWifi stops working. That never happens with my Vi or Airtel sim. Even though I turn on airplane mode I get VOWifi logo along with calls, SMS etc. On my Airtel and Vi sim. Let me know how can I fix this?

It is normal and this is have voice over Wi-Fi technology works. You have to have the SIM turned on for voice over Wi-Fi network to start, once started the signal moves over Wi-Fi
Mine works in airplane mode also.
I had prepaid sim of Jio.
