If you're willing to jump through hoops, you might want to check if it's still possible to setup an EIN and a new SMB T-Mobile 5G internet and get a static ipv4 for a small charge per month.

Personally, I had major issues with the 5g wan equipment and my network as well as a snafu with ordering... Sales rep put in the order for a static ip with a ssn based SMB account, but that got removed during provisioning and couldn't be added back. (And then billing issues because the account didn't get cancelled properly, either)
