Does T-Mobile Home Internet use CGNAT?

Short answer: Yes. T-Mobile Home Internet puts home customers behind CGNAT by default, according to T-Mobile Home Internet's own documentation plus customer reports. We found no way for home customers to opt out. Static IP: No. IPv6 is available, so devices can still be reachable over IPv6.

Can I self-host on T-Mobile Home Internet?

CGNAT by default?Yes

Confidence: Medium: ISP hints or confirms part of it; the rest is customer reports. T-Mobile officially says its gateways can't port-forward and IPs are dynamic. That CGNAT/464XLAT is the reason comes from customer reports.

T-Mobile says its gateways can't enable port forwarding and IPs are dynamic. Community reports: IPv6-only network with 464XLAT, so IPv4 is shared (CGNAT).
