• For users tracking vehicles across countries, global SIM cards may be a good solution. These cards are designed to connect to multiple networks internationally, offering flexibility for global GPS tracking. Unfortunately, compared to local operators global providers may offer quite poor coverage in distant locations.
• A local SIM card is a physical SIM you buy at your destination or region. It’s one of the most popular methods for getting cell service abroad because it’s a quick way to secure data. 

3. M2M // IoT  SIM Cards

• M2M (machine-to-machine) SIM cards are specifically designed for communication between devices, making them ideal for GPS trackers. M2M SIM cards often come with enhanced security features, better reliability, and long-term connectivity options, which makes them perfect 
• IoT (Internet of Things) SIM cards are used to connect smart devices, including GPS trackers, to the internet. These SIM cards are optimized for transmitting small amounts of data efficiently and securely. Mostly they are used in smart cities, logistics, and asset tracking.

Remember, you can check your local telecommunications company to get the best deal based on your goals and purchase amount, and test global providers in your area. Most of our GPS tracking devices operate within the country or the immediate vicinity, and it is important to have the best signal locally first and foremost.

Issues with SIM Cards for GPS Trackers

There are some of the most common issues GPS tracker users are facing in 2023-2024:

1. Network Compatibility Issues

Many GPS trackers were originally designed for 2G networks, which are now being phased out in many countries. This transition has created a significant problem for users still relying on older technology. For example, if your GPS tracker uses a 2G SIM card, it may become obsolete as more regions discontinue 2G support.

2. Signal and Coverage Problems

SIM cards rely on mobile networks to function, and any coverage gaps or weak signals can lead to interruptions in tracking data. Rural areas or regions with limited mobile infrastructure may not offer the necessary coverage, which can lead to inconsistencies in tracking results.

3. Data Plan Limitations

Choosing the wrong data plan can result in service interruptions, especially if you exceed your data allowance. GPS trackers require a constant data connection, so make sure your plan provides enough data for continuous tracking without excessive overage fees.

Remember, you should activate your SIM cards first before connecting with a GPS tracker.

Choosing the Right SIM Card for GPS Trackers in 2024

With the phase-out of 2G networks and the rise of 4G (and even 5G in some regions), selecting the correct SIM card for your GPS tracker is more critical than ever. Below are the key considerations you should keep in mind:

1. Network Compatibility

Ensure that your GPS tracker and SIM card are compatible with the available mobile networks in your area. If you are still using a 2G tracker, it's time to consider upgrading to a device that supports 4G or higher.

2. Data Plan Size

Different GPS trackers have varying data requirements. It's important to select a SIM card with a data plan that matches your tracking needs, whether for personal use or fleet management. A basic tracker might only need a few megabytes per month, while a more advanced system may require several gigabytes for real-time data transmission.

3. Global Coverage

If your tracking needs extend across borders, consider using a global SIM card that works in multiple countries without excessive roaming fees.

4. Cost Efficiency

While postpaid SIM cards often offer better reliability for business purposes, prepaid SIM cards may be more cost-effective for occasional personal tracking. Always weigh the costs against your specific tracking needs.

5. M2M and IoT SIM Cards

For large-scale or industrial uses, M2M and IoT SIM cards offer greater reliability, enhanced security, and the ability to transmit data over long distances without interruptions. These SIM cards are ideal for businesses that require continuous monitoring, such as fleet management, logistics, and asset tracking.

Access Point Name (APN)

Access Point Name (APN) is a middleman between a particular network and the GPS-trackers trying to connect to it, adding a layer of security to the devices on your network. 

For a GPS tracker, it is necessary to configure APN correctly to connect it to the server and transmit location information. Each telecommunications operator has its own APN settings that must be configured for the device to work properly.

The tracker is usually configured using SMS commands specified in the tracker guide. The commands are sent to the number of the SIM card used with the tracker. Most often, the guide to configuring the tracker is provided with the device. You can also request it from the seller or the manufacturer of your GPS tracker.

 Possible problems with APN settings when crossing the border of another country

When a GPS tracker crosses the border of another country, problems with APN settings may arise. This is because the APN settings of the telecommunications operator in the new country may differ from those in the home country. In such cases, it is necessary to reconfigure the APN settings to ensure that the GPS tracker continues to work properly. It is important to note that roaming charges may apply when using SIM cards in other countries, so it is recommended to check the pricing plans of the telecommunications operator beforehand.

 By understanding the importance of SIM cards and APN networks, you can ensure that your GPS tracking device is set up correctly and transmitting data accurately.

Conclusion

The landscape of GPS tracking is rapidly evolving, especially with the ongoing transition from 2G to 4G networks. Understanding the role of SIM cards in GPS trackers is critical for ensuring uninterrupted and accurate location tracking.
