Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

The Arduino is a great choice as it can easily decode the phone’s rotary dial pulses. The Arduino code takes all of the individual dialed numbers and combines them into a phone number.

This will allow the development platform to connect to the internet via GSM mobile phone networks. The module, or shield, was developed in conjunction with Telefónica’s Physical Internet Laboratory ...

Real Time Home Security System using GSM Technology-An Anti-theft System! This project deals with the design & development of a theft control system for home, which is being used to prevent/control ...

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.

The Siemens GSM modem in this build is nothing to worry about, but be careful if you try to reproduce this project with an Arduino GSM shield, or your house might really heat up.

Arduino has two new boards out which deliver connectivity – the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400. The Arduino MKR WAN 1300 delivers LoRa low-power WAN connectivity, and the ...

Adafruit has this week made available the Arduino FONA 800 that has been designed to provide Arduino development boards with the ability to enable Arduino cellular GSM via both voice and data. The ...

The device can be shipped along with Arduino’s Uno, MEGA, and Leonardo boards, and the GSM Shield itself comes with a SIM card. (You can, however, use whatever SIM card you like.) With the ...

It comes with either an Arduino board or the Cinterion EGS5 kit that is designed for developing prototypes in industrial scenarios. Developers who already have the hardware required can order the M2M ...
