An Arduino is equipped with a piezo sensor to detect impact, and a GSM shield takes care of the texting. It’s an interesting concept, similar to requiring police officers to wear body cameras.
The module, or shield, was developed in conjunction with Telefónica’s Physical Internet Laboratory and is available to purchase. The open-source GSM Shield comes with a Telefónica SIM card ready to be ...

Arduino has two new boards out which deliver connectivity - the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400.
The GSM Shield also includes a Telefonica SIM card that includes a worldwide data tariff which can be used anywhere there is a cellular signal.
If you've mastered the art of Arduino, but haven't yet been brave enough to toss in a bit of GSM communication, the how-to guides linked below definitely deserve your attention.
First, the ATmega48V only has one UART. This is connected to the GPS module at 9600, 8N1. The connection to the GSM M-590 module is only 2400 bps, and slow enough for a bitbanged UART.
