One of the most common questions from new Datalink customers is how much mobile data their GPS tracking devices will use. This article provides practical guidance to help you select the right SIM data plan.
How GPS Trackers Use Mobile Data
GPS tracking devices use mobile data in two main ways:
- Uploading tracking records — each time the device sends a GPS position, event, or alert to the platform, it uses a small amount of data.
- Downloading GPS aiding data — many GPS devices download AGPS (Assisted GPS) data periodically to speed up GPS satellite acquisition. This is a larger one-off data download that may occur daily or weekly.
Typical Data Usage by Device Type
Data usage varies significantly by device configuration. As a general guide:
- Hardwired vehicle trackers (high tracking frequency): 5–20 MB per month
- Battery-powered asset trackers (low tracking frequency): 1–5 MB per month
- Devices with Bluetooth scanning or additional sensors: slightly higher
Factors That Increase Data Usage
- High tracking frequency (e.g., a record every 30 seconds vs every 5 minutes)
- Frequent stop/start events generating additional logs
- Firmware update downloads
- Large numbers of Bluetooth scan records being uploaded
Choosing the Right SIM Plan
Datalink recommends M2M (Machine-to-Machine) SIM cards from carriers that offer:
- Low monthly data allowances (50 MB–500 MB per device is typically sufficient)
- Multi-network roaming for rural coverage
- No voice or SMS charges (unless required for specific features)
- IoT-specific pricing tiers
Network Technology Considerations
Most Datalink GPS devices support 4G LTE Cat-M1 (LTE-M), which is ideal for GPS tracking — it offers good coverage, low power consumption, and low data costs. Some devices also support NB-IoT for ultra-low-power applications. Check compatibility with your specific device model.
