jio Vo-WiFi not working on S10+

[Anonymous]

Hi All, 

I have a strange problem. I am using Samsung Galaxy S10+. In my phone, Jio & Airtel Wifi calling working. However, whenever I connect to my home broadband network, my Jio Wi-Fi calling gets disabled and turns off automatically. Airtel Wi-Fi calling continues to be working all the time. I have tried calling Jio & my broadband provider both, but no luck.

Can someone suggest how can I enable Jio Wi-Fi calling as well?

I tried changing MTU on my router and then jio vowifi worked a few times for a few minutes.

You should try a smaller value. If you can open command prompt, there is way you can determine the optimal MTU size by using the Ping.

1480 is the optimal value for my router. but jio wifi calling doesn't work
