Mobile Broadband in Up^2 edge computer
I wanted to check 3G/4G capabilities of the Up^2 edge computer that we have (https://up-shop.org/up-systems/292-up-squared-lora-edge-computing.html). Apparently, there should be a SIM-card in the edge computer (I've received an empty holder of such card stapled with the very short instruction on how to start the edge computer). When I open the networks menu in Ubuntu, I see the section Mobile Broadband, but it is gray and has only one option "not registered". I went into the settings of this connection to learn more, but all I see there are the basic settings filled in such as number, username, password and the APN live.vodafone.com. I don't really know how to enable this capability fully and really lack instructions to do so. Could someone kindly provide instructions or share the experience working with LTE on Up^2 edge computer?
