I'm going to push a fix for now that just overrides the healthcheck. I can confirm that fixes it on my end. Can you open a separate PR and/or issue...

@TeoTN - Note that the data plans for 4G/5G are pretty expensive if your Pi does anything more than a trickle of data... that's something I'm trying to figure out...

Step 1: Try to use the card on the Turing Pi. Inserted SixFab SIM and card in Mini PCIe slot for node 1 and booted. Neither `lspci` nor `lsusb` return...

@danmanners - It seems like that presumes a device is appearing in `/dev/tty*` already, which is not happening at least on my board. I wonder if maybe the Turing Pi...

Some more debugging steps: 1. Tried the card in the mPCIe slot for node 2 on the Turing Pi, nothing in `lspci`, `lsusb`, or in `/dev/tty*` either. 2. Tried installing...

 On a Pi 4 model B with the [USB to mini PCIe adapter](https://amzn.to/3mXBQYb), I get the following: ``` pi@lte:~ $ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation...

Following [SixFab's instructions](https://docs.sixfab.com/page/internet-connection-with-quectel-ec25-by-using-ecm-mode), I communicated with the modem via `minicom -D /dev/ttyUSB2 -b 115200` (after installing `minicom`), and here's the transaction history (the last command triggered a modem reboot, then...

``` pi@lte:~ $ dmesg ... [ 546.722909] cdc_ether 1-1.3:1.4 usb0: register 'cdc_ether' at usb-0000:01:00.0-1.3, CDC Ethernet Device, c2:a2:8a:5b:3d:f9 pi@lte:~ $ ip a 1: lo: mtu 65536 qdisc noqueue state UNKNOWN...

Testing the speed; first with all interfaces going: ``` pi@lte:~ $ sudo apt-get install speedtest-cli ... pi@lte:~ $ speedtest-cli --source 192.168.225.23 Retrieving speedtest.net configuration... Testing from Amazon.com (3.239.194.27)... Retrieving speedtest.net...

A few other notes concerning routing—SixFab seems to use a mobile network that's CG-NAT'ed behind AWS, as the public IP address in front of the LTE connection is: ``` pi@lte:~...
