Can these phones be used in Canada?

According to this list you are out of luck: VoLTE provider support

But @makrolon had something good to say in November 2024.

I spent three weeks in Canada (BC) and USA (OR,WA) this summer with my 10III SFOS v4.6 roaming with a Finnish SIM (Telia). I was expecting some issues due to different frequencies, possible problems with LTE support etc. but didn’t really come across anything network-related. I used mobile data daily for messaging and browsing, sent/received the occasional SMS but did only very few voice calls. I had network selection on automatic and never attempted any manual configuration (not sure it if even was possible).

During the trip I had two issues with the device - on arrival to Vancouver my phone chose an incorrect timezone with the automatic selection; it ended up in Toronto time zone, i.e. three hours off the correct time. I think at that point it was using the Bell Canada network. Also, a couple of times the device UI slowed down when moving in dense urban environments - probably due to wifi being enabled and the wifi scanning slowing it down to a crawl.

If you tell us your provider and the phone you are thinking about using, we can help you more.
(I recommend Xperia 10 III or the 10 V or the C2 (if you are not very knowledgeable as you say), but this can vary based on the frequency of your provider / country)

And throwing in a “sad but true” Sailfish is not a: “i am expecting things to go as smooth as, and be a drop in replacement for Android or IOS” it takes a bit of reading (not toooo much), and the willingness to learn new things. You do no have to be a nerd / geek, but it helps
