x750-EC25AF - SIM card not registered

Hello,

I have a brand new x750 using the EC25AF modem, with a Tmobile sim card and I’m getting the error: SIM card not registered.

I have tested this sim card in a phone, and it is working as expected. I have tested the same sim card in another device, and it is working as expected.

Is there anything I can try to get this to connect?
