I bought one of these Sierra GX440 to test with pfSense.
Anybody using this device?

I bought one for 60 bucks used-as-is.
Heck the MC7700 inside is worth 30 bucks…

I already re-assembled it and I am currently using it. Sorry but my flip phone camera is junky.

There has been a newer model released called Airlink GX450. This unit uses the MC7355 module.

If you can afford a 800 dollar modem!!!

The wireless module option brings it to $900

Unreal that it is only 2.4ghz wifi for that money. Single chain as well.

There are multiple versions of these as well for different carriers. There is an ATT version and a Verizon version. The ATT using the MC7700 and the Verizon version using an MC7750 module. The label on the bottom tells all the details. The Wifi module is an option they call X-Card. I was able to swap the module between Verizon version and ATT version. The firmware picks it up automatically.
I was hoping on crossflashing the firmware&modules between ATT and Verizon versions but that don't work. Circuit Board does has same model number and revision. The Sierra flash rom is a bin file when expanded looks like Linux with uboot file..

The device has a very nice interface and it has the best information about cellular signals and tower data I have ever seen. Very useful in pointing directional antennas.
