SMARTY uses CGNAT, I think that could be causing issues.

Recommend a different provider for gaming unfortunately (I use O2 personally and that's fine, I'd recommend ignoring any provider that uses CGNAT).

O2 are definitely behind CGNAT too.

The only mainstream network who aren't are the main Three brand when using their broadband APN rather than the mobile version.

The reason why EE worked for OP is likely because they support IPv6 and their addresses are all unique despite the shared CGNAT IPv4 Addresses. Maybe O2 is the same?

O2 doesn't have IPv6 support for me for anything other than IMS, test-ipv6 says no IPv6 address detected
