What is the difference between GPS, SIM, and FASTag tracking for trucks?

Contact Intugine to learn more.

A: GPS tracking uses a hardware device installed in the truck for real-time location every 30–60 seconds. SIM-based tracking uses the driver's mobile network signal for location updates every 5–15 minutes without hardware. FASTag tracking uses toll transaction data to confirm highway movement at toll plazas, spaced 50–200 km apart. Each has different accuracy, cost, and use cases.

Q: Which tracking method is most accurate for logistics in India?

Contact Intugine to learn more.

A: GPS is most accurate (5–10m, real-time), followed by SIM-based (100m–1km, every 5–15 min), followed by FASTag (toll-plaza level, every 50–200 km on highways only). For full trip visibility, Intugine recommends GPS as primary where available, SIM as fallback for all other trucks, and FASTag as a highway cross-check and lane intelligence source.

Q: What is the cost comparison between GPS, SIM, and FASTag tracking?

Contact Intugine to learn more.

A: GPS has the highest cost: device hardware (Rs 3,000–8,000) + monthly data plan (Rs 150–400). SIM-based has no hardware cost: SIM query fees are charged per trip or per vehicle-month (typically Rs 50–150/vehicle/month). FASTag data access is via API subscription. For tracking unowned third-party trucks, SIM is 5–10x cheaper than deploying GPS hardware.

Q: When should I use GPS tracking vs SIM tracking for my logistics operation?

Contact Intugine to learn more.

A: Use GPS when you own the fleet, need real-time geofencing (e.g. plant gate events), or are tracking high-value cargo where 30-second updates matter. Use SIM when tracking third-party transporters who won't install devices, running large-scale operations across thousands of trucks, or need to deploy instantly. Most enterprise logistics operations use GPS for owned assets and SIM as a universal fallback.

Q: Can FASTag data track a truck that has gone off the highway?

Contact Intugine to learn more.

A: No. FASTag only records at toll plazas on national and state highways. Once a truck exits the highway for urban or rural delivery, FASTag goes silent. That's why FASTag is used as a lane intelligence and route confirmation tool, not as a real-time tracking method. Intugine combines FASTag with SIM or GPS to maintain tracking continuity across the full trip.

Q: Does Intugine combine all three tracking methods in one API?

Contact Intugine to learn more.

A: Yes. Intugine's unified tracking API automatically uses the best available signal for each vehicle: GPS data if a device is present, SIM fallback if no device, and FASTag cross-referencing on highway segments. The API returns a single location object regardless of which source it came from, simplifying integration for developers who don't want to handle multiple data streams.
