Hi - I have two IPhones. One has an EU number, and I use it in the EU. One has a US number, and I use it in the US.
I have ONLY one Apple ID, and ONLY one ICloud Account.
BOTH phones are in my name, and are on the same Apple ID -- i.e., if I take a photo on one, it will sync to the other via ICloud. Nobody but me uses either phone, so it's not the same situation as the questions above.
I just bought the AirTags to try out on 2 items of luggage for a trip.
I was in the EU as the time, so I activated them to my EU IPhone. I checked the location from time to time - just learning how to use it.
I arrived back in the US, where I use my US IPhone. SAME Apple ID as the other one. I tried to locate the bags at baggage claim (again - they weren't lost -- I was just training myself in how to use them). They didn't show up on the U.S. Phone. I turned on my EU phone, and they showed up (along with a roaming charge).
Other things, like ITunes, Photos, etc. sync between these 2 devices. My question is why I can't seem to use my US phone with the tags, even though the US phone is on the same Apple ID as my EU phone.
Thanks for any help! :)
