If it’s a work phone, they should be paying for it, not you.
If OP is in the same situation as me, then he has a work phone that he can use privately as well. It's basically a free high-end phone. Am I forced (OP used that term) to use it privately? No. I could buy a second phone, put my SIM in there, and run around with two phones all day. Not going to do that, to many downsides. And since I can use that phone privately as well, my private phone data isn't going onto any servers my employer controls.
