Setup SMS forwarding with gammu on debian bullseye on a rasp pi B+ with the HUAWEI E8372h-320 (2020 model)

First and foremost we need to get the huawei into the correct mode. Unfortunately, usb modeswitch did not do this out-of-the-box for me.

Ensuring that the huawei stick does not switch into an incompatible mode automatically

Blacklist cdc_ether by creating a file /etc/modprobe.d/blacklist-huawei-cdc-usb-net.conf with the following contents:

HOWTO: Receive SMS via 4G/LTE Huawei stick on Raspberry Pi 4 and forward them via Telegram

I live abroad and have only 1 sim card slot in my phone. It holds the SIM card of the country that I am in right now. But I also have another SIM card from my home country which receives my banking SMS codes. I can't afford to lose the "home" SIM card, so I decided to keep it in my house and forward the SMS messages to my main phone and computer via Telegram (just like Whatsapp, but so much better).

I also made a choice to use a 4G/LTE stick instead of 3G, because the 3G signal in my area is getting worse in worse due to operators upgrading their equipment.

Prerequisites

1. Raspberry Pi 4
2. Huawei E8372 (but can be any similar)

Step 1 - Get the Huawei card to work properly with Raspberry
