T-Mobile SIM in US compatibility

Does the AutoPI work in the US on the T- Mobile network?

If it helps, I’m using a Google Fi data only SIM and it works fine. It’s a different APN since it’s a T-Mobile MVNO, but it’s ultimately on the T-Mobile network.

This should be the APN info for T-Mobile: https://support.t-mobile.com/docs/DOC-2090#subhead1

I could not get t-mobile to work, so I am not trying AT&T iot, only $2 a month per sim. We shall see how it works today.
