Does "Find My" features require an active cellular connection? Or does it work with only wifi?
I'm considering buying some AirTags for me and my spouse. We both have iPhones and iPads.
One primary use case would be for keeping track of luggage when traveling abroad: I'd like to know if my checked bag is following me on a long series of connecting flights, or "lost" in some airport half-way around the world, many hours behind me. But my phone's (and my iPad's) "home" cellular service does not work overseas (outside USA). When I arrive at my destination abroad, I typically buy a local SIM for my phone & iPad and I have cellular connectivity again (though with a different phone number). During transit (when I would be most keenly interested in keeping track of my bags), I am limited to wifi for connectivity. I'm fine with that.
My question is: Are AirTags and the "Find My" app going to be OK with that too (wifi connectivity only)?
Do all the features of AirTags and the "Find My" app (on iPhone and iPad) work with only wifi connectivity? Or do they require a cellular connection (to my "home" phone number that Apple associates with my phone)?
Before buying AirTags, I want to ensure the features won't be crippled without cellular connectivity to my home phone number.
(In case it matters: I do NOT have Two Factor Authentication turned on for my Apple ID...and have no intention of enabling it).
I'm sure this must be a pretty common use-case: you fly off to Europe, your home number no longer works, and you want to check to see if your bags with AirTags are still in Rochester or Rome...
Thanks for the insights.
