WAN Connection Settings > Network Mode

We are using several Pepwave MAX Transit Mini’s. They are all Hardware Revision 1. Only one of the devices displays this setting. They all have the latest firmware. Is there another setting that allows this selection to display? We would like to use a specific carrier to prevent the Mini from roaming onto another carrier, because it never goes back to the original carrier once it roams.

We are still experiencing this issue. The SIMs are all FirstNet.
