I know it's obvious but have you tried turning if off and back on again and checking for pending software updates?
Work's solution to my softphone protest was to give me a Samsung A21s and a data package; the softphone app (Horizon) runs on there using EE Data.
Took several attempts to get the phone to actually connect to data. Not just the softphone app that wouldn't work, no internet at all. Turning off/on (again) and/or a software update sorted it but I don't know which as I wasn't in 'one change at a time' diagnostic mode.
Work SIM in a spare phone of my own and it was fine.
The settings in an unfamiliar phone are a total maze.
