GatewaySMS

Overview

GatewaySMS is a NodeJS Express - Android system that convert an API request to a SMS.

Currently (2019) it is not possible to use internet network to send text messages to mobile phones. You must necessarily use the GSM network, therefore a particular antenna capable of connecting.
From a brief feasibility study it turned out that using a physical hardware device like Arduino (30 €) or Raspberry Pi (40 €) with the SIM900 shield Link (30 €), is not convenient, especially for the low reliability, the continuous maintenance required and non-portability.
Any Android smartphone can easily do the job, better if it has dual SIM support.

Installation

Open GatewaySMS-Server-NodeJS folder and use the package manager npm to install the needed components:

npm install --save express socket.io
npm install body-parser --save
