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

Read long SMS with python-gsmmodem (and send SMS with same running script)

I spend a lot of time to replace gammu with python-gsmmodem for my Huawei E3531.

The python exemple is just an exemple, it's incomplete. It does not read sms in the memory (if you receive a sms before starting the script). And it does not concat multiple parts sms (it will print unordered parts).
Also, as your live read sms script is running, you cannot send sms with another script because the dongle is busy.

Here is my own script to read all kind of SMS and send in same time.

Use ffmpeg to stream video from a dahua 4300s to a file or files

You can use ffmpeg to directly pull frames off of a dahua 4300s at full resolution. May be a good alternative to pricey dvrs which likely cannot record at full resolution, may not work with the camera, or are prohibitevly expensive

Simple Stream to file
