WiFi calling on Jio network.

[MajorShashi]

It's been over a week since I bought my first Samsung phone, S21+. I have Jio as my SiIM 1 and Vodafone as secondary. I have the WiFi calling option on for Jio but after a minute or so it turns off automatically. (WiFi speed and range is excellent, used to work perfectly on my previous phone, OnePlus 6T)

When I contacted Jio, they responded like they didn't even know this phone existed and I'm still waiting for a response from Samsung support. It's been more than a week. 

So need your thoughts on this. 

Edit - Thank you all for the suggestions. Apparently it was my WiFi networks problem. I just changed a setting and now everything works fine.

Have you tried WiFi calling In same same SIM but on other device which supports WiFi calling. If WiFi calling is working on other device than may be setting issues in your S21+.
Try it and than Give your response.
By the way if WiFi calling is working in Samsung device you will see this type of symbol↓↓↓

Which WiFi network are you trying to use ? Did you try it with some other WiFi network ?
