Unfortunately these are not marketed at all in the Western world and probably wouldn't work on domestic carriers.
A Nokia E71 was my daily driver for about a year, starting in 2010. I loved:
- the hardware (slim yet solid, keyboard only slightly worse than a Blackberry, nice tapered+curved edges)
- the extensive list of features (e.g. Wifi+3G, built-in SIP client, support for Exchange ActiveSync)
- support from important apps (e.g. Skype)
I hated:
- How finicky it was. I lost count of the number of times I had set up the mail client again (maybe after re-installing it) because it stopped syncing. (This was back when GSuite free accounts supported ActiveSync, which allowed push email.)
- The weirdness around selecting Wifi or 3G connection (I don't recall exactly what the issue was, but I remember there was something confusing about it).

FWIW it apparently uses an older, pre–Google-investment KaiOS.
Edit: It's $100 new which isn't too bad, but less than $40 open box on eBay and other sites. That's practically impulse buy territory. I'll definitely have to consider it.
