Galaxy S21 Ultra 5G Unlocked - No WiFi calling

[SMRose1924]

Hi- I see a bunch of posts on this on This forum and others BUT no resolution to fix this.

My phone is a Galaxy SM-G8890 S21 Ultra 5G.

This is an issue only with Verizon as if I add another carriers SIM (e.g.- T-mobile in SIM2) WiFi calling comes on BUT not available when I switch back to Verizon.

So, this is a VZW issue, not the S21 Ultra 5 G issue (i.e.- not a Samsung issue).

Does anyone have a resolution for this on VZW? I'd prefer to keep my VZW vs changing carriers.

Thanks for any help with this.

All the best
