A work colleague is travelling to the US in a couple of weeks and is spending a few days in NYC. She has been considering to purchase a new iPhone there since even getting a "free" model capable of working on any phone service provider, she'd be saving like $200-300. SIM cards don't seem to be an issue, nor 5G service, but someone told her that the geolocation services could be. I've done the customary search and wasn't able to find much about it.

Since many of you're mostly iPhone users and long distance travellers, you could possibly shed some light on this issue. Thxs.

While not technically Europe, friend who moved to London a year ago said he and his wife have had no issues with US iPhones, including geolocation. I don’t believe he’s switched over to eSIMs though, so not sure the complications there.
