It used to be that Three (UK), on the 3internet APN, would get you a public
(variable) IPv4 address.  Using the three.co.uk APN would put you behind
CGNAT.  I don't know if that's still the case.  I think the public IP still
had some degree of firewalling (so you couldn't run some protocols).

A&A will provide you a fixed IPv4 address on their data SIMs:

(appears to use the Three network and AQL's M2M service)
