After inserting a valid SIM card and connecting an external antenna, the module registers on the GSM network. Once connected, it can send and receive SMS, make voice calls, and transmit data over GPRS. The onboard RF circuitry manages cellular communication, while the host microcontroller controls operations using serial commands.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTypical Applications\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eIoT and M2M communication systems\u003c\/li\u003e\n\u003cli\u003eRemote monitoring and telemetry\u003c\/li\u003e\n\u003cli\u003eSMS alert and notification systems\u003c\/li\u003e\n\u003cli\u003eData logging and reporting\u003c\/li\u003e\n\u003cli\u003eSecurity and alarm systems\u003c\/li\u003e\n\u003cli\u003eVehicle tracking in 2G-supported regions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eBoard Dimensions (mm): 50 × 49\u003c\/li\u003e\n\u003cli\u003eWeight: 23g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 × SIM900 GSM GPRS Wireless Transmission Module\u003c\/li\u003e\n\u003cli\u003e1 × Antenna\u003c\/li\u003e\n\u003cli\u003e1 × Power Connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":48627770065148,"sku":"KG1363","price":649.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/SIM900GSMGPRSModule_1.jpg?v=1766985837","url":"https:\/\/kitsguru.com\/de\/products\/sim900-gsm-gprs-module","provider":"KitsGuru","version":"1.0","type":"link"}
