I have a T Mobile account and a Verizon account. Installed 2813 which has WiFi calling enabled for TMobile.
When I put my t mobile SIM card in my Z10, WiFi calling automatically appeared. I thought nothing of it because I expected it would work based on the forums.
I then had to do an autoloader install in my z30 due to systemapps errors when trying to run any Android apps. I was expecting some calls so I put my VZ SIM card in the Z10 while I reinstalled. To my surprise, when I rebooted WiFi calling was still there on the Z10.
Then during setup after the OS install on the Z30, I put the TMobile SIM in. Sure enough WiFi calling automatically popped up. I then decided to test if I could duplicate what happened with the Z10. I put the VZ SIM back in, rebooted, and, just like the Z10, WiFi calling still there.
I now can switch SIMs between Zs, between TMOBILE and Verizon and WiFi calling stays no matter which SIM or how many times I reboot.
Well, that is definitely the t-mo WFC symbol. The SYMBOL may remain when you put your VZ Sim back in but can't work. I read that the VZ version is only (currently) working on a couple of Samsungs. AT&T only works on iPhone and, as I am told, only works domestically. Unlike T-mo's version which works anywhere.
My splash screen has never changed... I've never seen the TMobile screen on my Z10 or Z30. Big Red screen regardless of SIM. I'll check the 10 again when I get home.
