@Danchvn - that link seemed to never be update to date anyhow. And the first statement in the below help article is not accurate as the link does not support what the statement says. I just submitted a ticket to CSA to tell them this, whether anything comes of this or not who knows.
The important thing about compatibility is the frequency bands anyhow, which is listed below.
I previously had the S20. I miss the MicroSD slot but at least the S22 is available with 256GB of storage. I find that the finger print sensor is more responsive, and can detect from multiple angles, beyond what is scanned in. The size is just right.
I decided to upgrade since my S20 was 2 years old. It seemed like a good idea due to uncertainties with supplies and rising costs. At the time of purchase, the S22 was a little less than the S20.
