The RF-V18 is a compact GPS tracker designed for discreet personal protection and reliable Green-Gps compatible operation. Its quad-band GSM/GPRS connectivity and multiple positioning methods (GPS/A-GPS/LBS) make it a practical choice for caregivers who need real-time tracking, SOS alerts, and two-way voice communication through a web platform or smartphone app. Small and lightweight, the RF-V18 fits comfortably on a lanyard for children, the elderly, or other vulnerable users while maintaining long standby performance.
Green-Gps compatible out of the box, the RF-V18 transmits location and telemetry to cloud platforms via GPRS (TCP/IP) and supports SMS-based fallback when needed. Caretakers can use Green-Gps to view live location, receive geofence and low-battery alerts, and manage tracking intervals. While the RF-V18 excels as a personal GPS tracker for safety and monitoring, it is not intended for vehicle-focused telemetry such as fuel monitoring, ignition control, immobilizer functions, or Bluetooth sensors used in advanced fleet management.
Key Highlights
- Green-Gps compatible real-time tracking via GPRS (TCP/IP) and smartphone/web platforms for immediate situational awareness.
- Compact, lightweight design (40 × 34 × 14 mm; 27 g) for unobtrusive personal wear or lanyard carry.
- Quad-band GSM/GPRS (850/900/1800/1900 MHz) ensures wide network support and SMS fallback for reliable alerts.
- Built-in 520 mAh battery with optimized low-power chipset delivers approximately 12 days (≈300 hours) GSM standby.
- SOS button and two-way voice calling to up to five authorized numbers for rapid emergency response.
- Multiple positioning modes (GPS, A-GPS, LBS) with quick cold/warm/hot start times for dependable location fixes.
- Geofencing, low-battery alerts, G-sensor assisted power saving, and temporary high-frequency “tailing” mode for concentrated monitoring.
How It Works with Green-Gps
The RF-V18 integrates with Green-Gps by transmitting location and event data over GPRS (TCP/IP) to the Green-Gps server or, where supported, by delivering SMS notifications. Once paired with Green-Gps, the device updates position data and status in near real time, enables configurable alerting, and allows caregivers to manage tracking behavior from the Green-Gps dashboard or mobile app. Commands and routine configuration can be handled through the phone app, reducing the need for SMS command strings.
- Real-time tracking updates via GPS/A-GPS, with LBS as a network-based backup where satellite reception is limited.
- SOS alerts and two-way voice calling routed to authorized numbers; alerts also forwarded to Green-Gps for centralized notification.
- Geofence entry/exit notifications and temporary “tailing” (1-minute update intervals) for close monitoring during high-risk periods.
- Low-battery and G-sensor events sent to Green-Gps so administrators can respond proactively to device-state changes.
- App-based configuration supported; Green-Gps receives the same telemetry for reporting, dashboards, and historical playback.

Use Cases
- Child safety: discreet wearable tracking with SOS and two-way voice for quick response to incidents.
- Elderly monitoring: geofence alerts, low-battery notices, and voice monitoring help caregivers keep seniors safe.
- Personal protection for vulnerable users who need an unobtrusive GPS tracker with reliable real-time updates.
- Temporary close supervision: use “tailing” mode for short intervals where one-minute updates provide tighter visibility.
- School or activity oversight: centralize location and alerting in Green-Gps for group monitoring and incident management.
Why Choose This Tracker with Green-Gps
When integrated with Green-Gps, the RF-V18 becomes a purpose-built personal safety solution that combines compact hardware with cloud-based monitoring. Its Green-Gps compatible GPRS reporting and SMS fallback ensure caretakers receive timely, actionable information: live location, SOS events, geofence breaches, and battery state. The long standby life, small form factor, and two-way voice calling make it especially well suited for child and elderly care programs where unobtrusive, reliable protection matters.
Note on scope: RF-V18 is optimized for personal tracking and emergency communication rather than vehicle telemetry. It is not equipped for fuel monitoring, ignition/immobilizer control, or Bluetooth sensor networks commonly used in fleet management. For Green-Gps users seeking a compact, trustworthy GPS tracker for human safety and caretaker workflows, the RF-V18 offers dependable real-time tracking and essential alerting features without unnecessary complexity.
Set Up RF-V18
Use with a tracker
-
Set the Operator APN
CountryCarrierAPNinternet.comcel.com.coUserCOMCELWEBPasswordCOMCELWEB
- Check your tracker clock setup is set UTC-0 or GMT. (The most trackers come from the factory on UTC.)
- For most devices you should use IMEI (International Mobile Equipment Identity) number as unique identifier. However, some devices have vendor specific unique identifier, for example TK-103 devices use 11-digit identifier.
-
Set Up the IP and port on your tracker: (automatic detect tracker's protocol.)
IP 54.85.159.138 Port 8888 - Add on your Account on devices with the IMEI or unique ID.
