From Fairphone's US order page

> Critical Notice: The device does not support LTE Band 13 (Verizon's primary coverage frequency).

Presumably that frequency isn't used in Europe? It also says that it's "not certified for use on the Verizon Wireless network." I don't know if that means Verizon might block it (which sounds like a very US thing) or it's related to not supporting the frequency that Verizon uses for LTE.

Because the United States sucks in regards to mobile phone compatibility and spectrum allocation. https://share.gemini.google/u6E8mAiITMcJ

What is that link?

The evolution of low effort copy+paste LLM response. Now Google can track everyone who wants that information and people can be just as rude as before when they copy+pasted LLM responses into conversations, but now it's sly.

That's been true for much of the history of cellular networks, as far as I know - universal standards in Europe, US phones can't (always) be moved between service providers. It used to be even worse in the US, with phones locked to individual carriers regardless of technology.

That's some of the European over-regulation that everyone complains about, compared to unfettered American competition.
