At a previous company I declined the "perk" of the company paying for my phone plan, because it required giving them control over it. I was mostly worried about losing my phone number accidentally upon parting ways.

Nowadays, Android can have a Work profile that your company can control (and wipe, for example) that doesn't affect your personal stuff. It's actually convenient because you have a separate instance of Chrome, which is a good workaround for mobile Chrome not supporting multiple profiles inside the app like the desktop version does.
