Review on 📶 Yeacomm 4G Outdoor CPE WiFi Router, Yeacomm 3G 4G LTE CPE Kit, LTE Unit with Sim Card Slot + WiFi Indoor Hotspot, 150Mbps CAT4 Mobile WiFi Router for USA/South America B28, Non-Compatible with Verizon" by Ryan Turner

On a 30ft wand versus a single cell it shows lower dBm than our phones and tablets. Idle restart. Becomes inactive when uploading a 1GB file or using speedof.me. It will restart later and the slow service will continue. Switching from ATT, Puretalk or Red Pocket SIM still works the same way. I did not find the source of the firmware. The web interface is nice, offers a lot of information, but doesn't change when the device stops transmitting data. I like having a transceiver on top, POE, an internal hotspot, and no physical connection to my computers, but it fails.
