2 iphones, 2 different Apple ID's = somehow linked to each other
I looked at some issues that people wrote about like 7 years ago, and I haven't seen the answer to my issue...
I have 2 different iphones (1 personal and 1 work) with 2 different Apple ID's. When certain people facetime me through my personal phone# it shows up on my work phone at the same time. Yesterday I called a friend of mine and they said that the caller ID was my company's name (this is on my personal phone).
I have signed out from my personal phone and signed back in (again, these are 2 different Apple IDs); when my Mom facetimes my personal phone after trying the sign out-sign in, it didn't change, the same thing is happening - the facetime is calling on both phones.
I did check the settings - none of the phones share any # or any emails, not even same payments. My phone carriers are completely different.
Can anyone help me with this?
