I just switched from a Huawei to a S23. My cell provider is Virgin (same towers as Telus in Canada) Anyhow im experiencing 3 problems and looking for advice.

1 Messenger wont open and just keeps saying "running security checks" but then won't load, sometimes it works if I go through Facebook but not the app directly

2 I live in an area with pretty bad cell coverage and so at home I rely on wifi calling however when I've tried to turn it on it keeps saying need to add emergency contacts when on wifi an with coverage. Which I've done but for some reason I still can't make a call when at home over wifi

3 When not on wifi loaing websites and apps seems way slower than my old phone. Would that make a difference if the provider is still the same?

Thanks for your help. So far the camera is amazing g and the usability fairly similar my Huawei.
