The Woo Posted August 22, 2020 Posted August 22, 2020 (edited) I would love to see support for modems based on the SIM7070G chip. Along with Quectel’s BG96, SIMCom’s 70x0 and 7x00 families seem to be the leading choice when it comes to IoT-related applications with LTE-M and NB-IoT. Shenzhen-based AND Technology manufactures and offers two very affordable modems (< USD 25) using the SIM7070G: BK-SIM7070G (a break-out board with serial interface) -> AliExpress DG-SIM7070G (a USB stick/dongle) -> AliExpress Sidenote: Waveshare has a Raspberry Pi HAT based on the very same chip –> SIM7070G Cat-M/NB-IoT/GPRS HAT SIMCom as chip provider offers excellent documentation on their website. I've put all files list below in a ZIP archive which can be downloaded here. I've also opened a github issue on this, in case you want to discuss there. Edited August 22, 2020 by The Woo

Take a look at ModemManager along with libqmi/libmbim... should support this out of the box with the packages installed. It's a Qualcomm MDM9205 solution, similar to QuecTel and others.
Thierry Rivier Posted October 27, 2020 Posted October 27, 2020 Hi, the 7070G seem work with https://core.docs.ubuntu.com/en/stacks/network/network-manager/docs/configure-cellular-connections tested on Armbian 20.08.4 Bionic just now need made more test EDIT : the interface is now write "enx00a0c661ebc0:" but not seem work
Thierry Rivier Posted October 28, 2020 Posted October 28, 2020 it work !, in fact i was not use the network-manager ,but use the ppp package with "SIM7070_SIM7080_SIM7090 Series_Linux_Application Note_V1.02.pdf" exemple for the script . 7070G is slow , but for IOT it's perfect 1
