The SIM800L draws up to 2 A peaks; use a battery capable of 2C discharge or a 5 V \/ 2.4 A USB supply. Screw on the included GSM and GPS antennas and insert an active 2G SIM card (not included) before powering up.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino IDE?\u003c\/summary\u003e\u003cp\u003eYes. Install the ESP32 board package and select “ESP32 Dev Module” from the board manager. The GSM and GPS modules work with standard SoftwareSerial or HardwareSerial libraries.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat SIM card do I need?\u003c\/summary\u003e\u003cp\u003eAny active 2G SIM with SMS and data plan works. In India, Airtel and Vodafone Idea still support 2G; Jio does not. Use a nano‑to‑micro adapter if necessary.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes the GPS work indoors?\u003c\/summary\u003e\u003cp\u003eDirect line‑of‑sight to satellites is required. Indoor use typically fails. Place the GPS antenna near a window or outside for a reliable fix.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
