> T-Mobile coverage and speeds are great.

Not in EU :D

I don't know how pricing compares to local brands, but T-Mobile is majority-owned by Deutsche Telekom. I imagine this explains a related benefit:

"With our Magenta plans, you get unlimited texting and data in 210+ countries & destinations. No international data-roaming charges. No setup. It just works the minute you arrive."

https://www.t-mobile.com/coverage/roaming

In the fine print, that page notes that international data is limited to 128kbps (or 256kbps if you're on the top-tier 'MAX' plan).

Phones that are designed for (or sold through) T-Mobile US won't necessarily work on T-Mobile NL, because they operate on different frequency bands, take advantage of different CA combos (combining different frequency bands for better coverage/speed), etc. The phone would likely also be locked to T-Mobile US for a period of time after purchase.

Good catch!

No problems in the Netherlands. They like to pride themselves on being the country’s best network.

Ok that was not my point and I forgot that the T-Mobile brand existed in some EU countries. But my point was that the phone wasn’t available outside of the US.
