Use old iPhone (no cell access) with Signal?
I recently upgraded my iPhone SE2 to a 17e. I set the SE2 up as sort of a PDA, where it's on wifi and I can do most things with it. I even have Google Voice on it so I can make wifi calls. The one thing I can't seem to do is use Signal on it. I'm thinking that's because Signal recognizes that it's a cell phone and wants to set it up as the primary device, correct? I don't suppose it's possible to work around that and set it up as just another linked device, like an iPad?
