Features: - Control electrical appliances remotely via phone call or SMS using a GSM-enabled mobile phone. - Operates anywhere with GSM network coverage. - Supports up to 5 authorized phone numbers for remote control. - Compatible with water heaters, electric motors, automatic doors, lights, rice cookers, and other standard AC-powered devices. Notes: 1. This device only provides on/off power control—no additional functionality. 2. Works directly with standard appliances; for appliances requiring manual button presses or with memory functions, compatibility may vary. 3. Requires a standard global GSM SIM card (2G only). Not compatible with 3G, 4G, or CDMA networks. Activate the SIM card before inserting it into the device. 4. For cost efficiency, use a SIM card with free incoming calls and SMS. Only minimal SMS fees may apply. 5. Ensure Caller ID is enabled on the SIM card and that sufficient balance is available for calls and messages. 6. Avoid installing the device inside metal enclosures (e.g., metal cabinets or tin boxes) as this may block signal reception. 7. In areas with weak GSM signal, SMS-based control may experience delays or failures—this is normal under low-signal conditions.
