Been looking for a phone upgrade and my dad has an iPhone (iPhone 13) given to him by his work, which he doesn’t use anymore. He offered to let me use it on the condition that the company can’t see that it’s being used.
Based on what I’ve seen, the only way that a company IT department can track usage of an iPhone is through MDM or a connection to a company network/company cell network; and afaik there wasn’t any MDM on the phone to begin with. He performed a factory reset on the phone before giving it to me (Erase All Content and Settings), and I’d be using my own personal SIM, connected to my own personal network. He has also never used these company phones with a company SIM and has always used his own personal SIM and network for these kinds of devices.
I know that a lot of these new iPhones have an eSIM inside them, so would it be possible for the IT department to track whether it’s being used or not through that eSIM ICCID, even if the eSIM is not being used? Furthermore, are there any other ways that a company might track whether an iPhone is being used or not? HWID maybe?
