Has anybody from the Arduino team further information what's going on in this case? The GPRS/GSM Shield provides you a way to use the GSM cell phone network to receive data from a remote location，it delivers GSM/GPRS 850/900/1800/1900MHz signals for Audio, SMS and GPRS Service. GPRS Shield is base on SIM900 4 Frequency GPRS module. It allows for voice calls, sending SMS messages. Price Match lets you match the price of any item sold and shipped by RobotShop with a competitor's price!. A SIM-card holder is located on the underside of the board (SIM-Card not included. Based on GPS GPRS / GSM SIM808 module, this shield can be used with Arduino (UNO, Leonardo, Fishino, NUCLEO, XNUCLEO) to create IoT projects (Internet of things) such as data acquisition, remote controls, GPS locators, etc. This GSM/GPRS/GPS Shield is an Arduino shield based on the Quad-band GSM/GPRS/GPS module SIM808. Arduino GSM Shield allows an Arduino board to connect to the internet, make/receive voice calls and send/receive SMS messages.
The official one sold by Arduino is 71 euros for me (I live in Europe), and third party ones have similar prices. SIM900 850/900/1800/1900 MHz GPRS/GSM Shield Development Compatible Board Module Kit For Arduino GPIO PWM RTC.
