There is no 4B+. 3B+ or 4B?I'm using Network Manager on my Pi 4B+ running Raspbian x64 (headless) to manage networking.
Show output of dmesg.I see that the "usb0" interface for the USB modem just randomly appears and vanishes while doing even a simple ping from the Pi.
It is likely that the dongle isn't able to get enough power. These LTE dongles usually draw a lot of power when active and the Pi USB ports are current limited. The fix is to use a powered USB hub.
