“Nice bit of kit for getting LTE/3G/2G cellular data access on a Pi or other device. I'm using it for remote telemetry/monitoring on a Pi based logger system.
Needs a bit of fiddling to get set up on R-Pi, and I initially went down a rabbit of dead-ends following outdated setup guides that don't apply to Debian Bookworm or Trixie with different modem/network manager tools. These actually make it fairly easy to configure and run the dongle as if it were a network adapter.
The inclusion of GNSS/GPS on the modem module is a bonus, though that requires a separate antenna and uFL adapter cable.
Also watch out for power brownouts when plugging this in to a running Pi - it seems to draw a fairly large surge current on hot-plug, so best to power up the Pi after plugging in this modem.”
“Used one of these with a Pi 3A+ to make a battery powered system sending automated messages over PMR radios using cloud based voice synthesis in a slightly rural situation. Found reception/reliability excellent. It's very obviously an "industrial/enthusiast" device not a "consumer" one and I mean that in a positive way. I intend to explore using it with microcontrollers as well.
Be aware when configured as an RNDIS device for a Raspberry Pi/Raspbian I found it didn't work with Network Manager's automatic setting of DNS servers. IP connectivity came up but DNS would be set then unset shortly after. To fix this I disabled management of DNS by Network Manager and set them manually to the Google ones.
Here's what I did...
sudo nano /etc/NetworkManager/NetworkManager.conf
And add this to the [main] section:
dns=none
rc-manager=unmanaged
sudo nano /etc/resolv.conf
Add...
nameserver 8.8.8.8
nameserver 8.8.4.4
...which worked as of October 2025.”
