Wifi calling option disappeared after 14.3 ios upgrade for Jio esim

SOLUTION: I also faced the exact same issue, 2 days back i update my iPhone to IOS 14.3, and the wifi calling option disappeared from the setting. To get it back I had to do Factory Reset of iPhone "Erase all contents and setting". After which the wifi calling option reappeared under Setting->Phone

i faced the same problem .. I connected my iphone xs to itunes, through my laptop and it automatically updated my carrier settings and the wifi calling toggle was back ..

I am facing the similar issue after upgrading to IOS 14.3 this week & tried calling Apple Support as well as Jio Care but it seems Jio support executive does not know the W of WiFi Calling Support and moreover they asked me to send an email to log a case saying they can’t log a case through call.

Apple Care wants to have a ticket number from network provider and network provider say this is iPhone feature and they can’t do much 🤪 I think I will have to port back to Airtel 🤓 pathetic support from Jio.

I tried resetting the network settings, Apple support executive was not sure if that would result in loss of eSIM settings or Data Plan, and I happily offered myself as their guinea pig 🤪 and fortunately it didn’t result in loss of data plan. I also tried soft reset of iPhone as well but no luck.

conclusion - the customers are left at their own fate due to software bug caused by this update, lesson for me - not to enable auto update of iPhone and wait for stable release.

Solution: I also faced similar issue...i just went to General—>About and clicked on Carrier and that triggered the update of my carrier settings...wifi calling got re-enabled

Simply go to About and Reset Network Setting .. Wifi Calling will Reappear!
