Group MMS broken on my line after porting in. RCS, iMessage, and 1:1 SMS all work. eSIM reissue keeps provisioning wrong MMSC

Already done: every step in the public troubleshooting doc, plus manually entering the correct APN/MMSC values (h2g2, m.fi.goog/mms/wapenc, 23456789) with restarts. No change. Then deleted the eSIM and reactivated through the Fi app. Provisioning pushed an APN of “wholesale” with MMSC wholesale.mmsmvno.com both times instead of the documented Fi values.

Control case: my wife’s iPhone on her own separate Fi account, same model, same visible settings, group MMS works fine.

Possibly relevant: this number lived in Google Voice 10+ years ago before porting to T-Mobile, and the recent port in to Fi was contested on T-Mobile’s end. Nothing shows in voice.google.com now.

Support chat ran the standard script and the session closed overnight, now on an email ticket. This looks like line-level provisioning that only the backend team can fix.

Anyone seen wholesale.mmsmvno.com pushed to a Fi iPhone eSIM, or a ported line come through with group MMS unprovisioned?

Fi team folks: happy to DM account details, ticket already open.
