I have an iPhone and an iPad. My iPhone is used for my job, as well as for personal things. I have an iPad that has service with another carrier (Verizon through work on phone, AT&T for iPad - the old unlimited program that started with the first generation iPad). My Apple ID uses my phone number. The iPad has a different number associated with the SIM, but when I go into Settings, there is not an option to use that number to send and receive messages on the iPad -messages are to/from the number associated with the Apple ID and the phone. I have tried to add the iPad number to my Apple ID, but it has to verify by sending a message, and I can’t get a message at that number until it is associated with the ID. So I can’t verify it. Circular problem. What I am trying to do, for privacy reasons, is to be able to send and receive messages on my phone, for work, using my phone number, and on my iPad, using the number associated with the iPad SIM. Even though I own my phone, since I have to give some control of the phone to my company in order to ensure security (for patient information - I’m in healthcare), I am concerned that management has the ability to read text messages on my phone. I don’t care if they read my work related texts, but not my private ones with friends and family. Do I just need to get a second Apple ID and set that up on my iPad, and link it to the number associated with the SIM? If I can avoid a second Apple ID, I would prefer that, but I’m not sure it’s possible.
