Not good for dumbphone enjoyers. I specifically bought a sonim xp3 because it had 4g + VoLTE. It's all very confusing, but it sounds like it won't work when I land back in Australia, regardless of whether I'm willing to switch networks.
Our team runs into errors (changes not syncing, etc.) on a regular basis 'collaborating' with Excel. definately doesn't work like magic in my experience.
Couple of instances where I want to be able to type _very_ quickly is when I'm (a) taking notes while someone is talking or (b) writing out a lengthy code block I don't need to think that hard about. Other than that, typing at a modest speed is good enough.
