2 cellular connections

Hello,

I have an MX67C in the field now with Verizon service. I want to plug in an aircard via the USB port with AT&T service. Can this work on the MX67C?

Can i remove the Verizon sim that is inside the MX67C and use only the aircard on AT&T service for connectivity on the device?

the MX will prefer an external USB modem to the internal modem, if available

You can only use supported usb sticks on the port https://documentation.meraki.com/MX/Cellular/3G%2F%2F4G_Cellular_Failover_with_USB_Modems#Compatible...

Short answer is yes. Check the documentation below. Also confirms USB will take precedence. Also note LTE is only supported in fail-over, not primary.
