Do you know if it is possible to setup a phone number with them if you are not a
US citizen?

Here is my experience, YMMV.
If you are in the US, they will sell you a prepaid plan. No problem.
Notice, Tello does NOT provide international roaming service. I have Tello and Tello confirms this on their website here:
Tello: Do you offer roaming?
"
Canada & Mexico
Tello does not have a network in Canada or Mexico and so we do not offer full service in either of those 2 countries and there is no roaming available."
They claim Wi-Fi calling & Text, but in reality, it's only Wi-Fi calling. Not Wi-Fi receiving There is no room in the app for even a text.
I've had Tello for +2 years. When I fly into the US it works fine. It doesn't work in Canada or Mexico for Wi-Fi call receiving or Texting (sending or receiving). You can call another phone via Wi-Fi though, but for this I use Skype.
It doesn't work in Europe, and it doesn't work in Argentina, Brazil, Paraguay, etc, either.
I am in their forum community and some "people" claim it works despite Tello's own disclaimer, but I suspect "oversight" on their part.
You can try it and let us know, but if someone was holding a g** to my head for the truth, I would say it doesn't work without any hesitation.
Good luck!
Most banks nowadays will tell you:
My system is saying this is not a compatible phone number.
The bank operator doesn't even know why.
