The modems can be used to increase the efficiency of maintenance and communication, but do not require extensive training. In addition, the modems can be mounted on a DIN rail or wall. You can only place and receive SMS with other SIMs on the Movilforum network. It’s not possible to create a server that accepts incoming requests from the public internet. The Arduino GSM shield allows an Arduino board to connect to the internet, send and receive SMS, and make voice calls using the GSM library.
You may use any SIM that works on a network in your area. Before buying the shield please verify that there is this kind of coverage where you plan to use it. GSM Library The GSM library handles communication between Arduino and the GSM shield. From the Arduino perspective, the Arduino GSM shield looks just like a modem.
Insert the SIM in the plastic holder so the metal contacts are facing the shield, with the notch of the card at the top of the bracket. Correct operation involves installing a SIM card, registering the number, and authorizing at least one mobile phone to work in conjunction with the device.
