They seem to work fine on T-Mobile. I hear the Palm Phone had some issue with Verizon where it only worked as a "companion phone" and I hear AT&T limits what phones are allowed somehow, but I cannot speak to those things.
They only have 4G rather than 5G. This has not bothered me but perhaps it would bother others.
