Guess it's time to opt out of T-Mobile entirely. Bummer, switching is pure overhead. :/

These days I use a Fi data-only SIM in a battery-powered travel router that runs a VPN, and only ever use my mobile devices via Wi-Fi to that, anyway. I use throwaway gmail accounts with Google Voice for stuff that still insists on PSTN phone numbers.

I kept my T-Mo SIM with my decade-old phone number (in a $19 dumbphone, no less!) but it might be time to abandon that now.
