Maybe Apple are intentionally making it hard so that they avoid the backlash from people calling and texting from the wrong number? The specific use case of using a work phone when abroad to avoid the cost to me makes me wonder why not just use the work phone full stop? Surely if you’re texting someone from two lines you have two different threads on the other persons phone, which personally would drive me mad, to the point I’d just settle on calling/texting on your work phone.
If you turned off the personal SIM, would it default to using the work line as the only one available?
