LG G8X ThinQ - no wifi calling option visible (Fido)

[eklmn]

I bought this phone in Costco unlocked 3 years ago. LG G8X ThinQ, Model LG G850UM40c. Single screen (but initial setup done for dual). Android 12. Provider - Fido.
Recently tried to set WiFi Calling but was not able to find such menu option neither in the Phone icon or in the general settings.
Any advice/help would be appreciated. I do not want to by another cellphone just because of this problem. I presume that all LG G8X ThinQ phones supposed to have this feature.

WIFI calling on phones not purchased from the carrier can be a crap shoot. Call your carrier for help.
