Hello,
From the attached troubleshoot, I can see that this device is using a European module, meaning it cannot be used in the US, as all of the US carriers require the devices to be certified on their networks. Order code RUT950 0***** does not have these certifications, thus even if they connect to the US operators, they will get blocked sooner or later.
As for the global SIM, while it will not get blocked, the lack of US band support will render the device unusable in the US market.
The correct order code for the US market would be RUT950 W*****, which has band support and certifications for all US carriers.
Best regards,
