Dual sim ( nano sim + e sim )

Hi,

I’m facing issue with the dual sim on my iphone 14 pro max, i have seen other users reporting same for iphone 13 pro and above. I use the nano sim and esim on my mobile, both work good when there is no call made, but when I make a call through any of my sim, the other sim’s network goes off to No service. Its vice versa for both. And from one of the user I got to know it is fixed when wifi calling is turned on the issue doesn’t work occur. I tried this but it works only for one sim which has wifi calling option turned on, the other sim still face same issue when i make a call on my secondary sim which has no wifi calling option set as the primary sim uses that option, the issue persist, primary sim goes off with no service. I believe this is not a carrier or network provider issue since there are many other user reported same for different networks and sim. Please can you help here?

Thanks,
