My folks only have WiFi on vacation, what is the easiest messaging app to bridge from iOS to GrapheneOS wo/GP? - Lemmy.world

Need something achievable for an extremely tech illiterate person on iOS. I got told about this after they are already gone and have no access to the device, but am asked to solve the problem.

This sounds tricky…

The only iOS message bridge i’m aware of is AirMessage, and that requires a Mac computer to act as the app’s server

They asked for any cross platform messages app, not an iMessage bridge. I’d say Element
Oh oops, my bad - I misunderstood the question…
Don’t blame yourself, it was extremely poorly worded and unnecessarily confusing.
