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

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

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

Install the fork of the mjpg streamer with the support for the raspberry pi cam

https://github.com/jacksonliam/mjpg-streamer.git

Enable the camera in the raspbian configuration settings accessed with:

sudo raspi-config

Test the streamer

Heroku CLI

How to Run a Script as a Service in Raspberry Pi - Raspbian Jessie

By: Diego Acuña

Original Article: http://www.diegoacuna.me/how-to-run-a-script-as-a-service-in-raspberry-pi-raspbian-jessie/

A pretty common task when using this device, is to run some script (for example a python script) as a service in the operating system so it can start on boot, stop and restart using systemctl and more. In this post I'm going to explain how to set a little script as a service using Raspbian Jessie in a Raspberry Pi.

Example Python Script

what?

Route all traffic with a raspberry pi like a VPN.

steps

get raspbian up and running https://www.raspberrypi.org/downloads/raspbian/
turn on ssh https://www.raspberrypi.org/documentation/remote-access/ssh/README.md
maybe update your packages

The purpose of this document is to get you familiar with the concepts and command line tools involved with connecting to the internet using modern 4G LTE modems on both Debian/Ubuntu and OpenWRT.

This writeup is based on my experiences with the Sierra Wireless AirPrime MC7455 modem and a Calyx (Sprint) SIM card, but it should apply to most modern 4G LTE modems.

High level overview

These are the steps required:
