If I have to pick between T-Mobile and Google, I pick T-Mobile. Google is going to kill Fi and Voice one day, T-Mobile is not. T-Mobile has some customer service, including stores, Google has none. Was able to migrate a physical SIM to an eSIM in a store in ~30 min. You can even move your Google Voice number to a T-Mobile DIGITS number for similar functionality.
(T-Mobile customer for 2+ decades, least terrible option imho)
EDIT: > Google Voice app may be slow but it does work every time
Until it doesn't! Fair critique though. I can also recommend the "Unlisted" iOS app for this purpose.

You had my interest...till i read the reviews of the DIGITS app on the app store. 1.9 average, most complains about it not working at all. Google Voice app may be slow but it does work every time
