There's also https://github.com/GNOME/mobile-broadband-provider-info
but since all of these are likely submission driven they may be
incomplete.

For example, neither have Bug Tussel (311-33) which is small roaming

https://docs.routee.net/docs/list-of-mccmnc-codes

does. Point being, nothing will be complete, but most should be valid
for larger carriers.
