I just purchased the Sonim XP3 plus 5g through Koodo. The phone was delivered 2 days ago. I took the Koodo sim from my iPhone 15pro and put it into the Sonim. We live rurally with no cell service, wifi calling is all we use at the house.
When I go to toggle on the wifi calling where it says "off” it just bumps me back to the settings menu and doesn't change anything. I've tried this while connected to wifi and lte at the same time. Didn't work, went into the local Telus/koodo store today and she couldn't figure it out. She told me to call Koodo. After an hour on the phone I was told the Sonim XP3 plus 5g phone does not support wifi calling? Surely the agent was mistaken. I'd rather not send in this brand new phone if I've been ill advised.
Can someone please advise whether this phone should support wifi calling? It does on other networks and the option is in the settings menu.
Thanks for any help.
