Everything You Need to Know About SIM Cards for GPS Trackers

The Increasing Need for GPS Tracking Devices

In the digital age, tracking and security have become synonymous with GPS trackers. Whether you’re a business tracking your fleet or a traveller keeping tabs on personal luggage, these devices have undeniably solidified their place in the tech realm. Renowned manufacturers like Skywonder, based in the heart of tech innovation, Shenzhen, China, offer advanced solutions for diverse markets spanning from Kenya to the UK.

Why Do GPS Trackers Need a SIM Card?

GPS trackers are marvels of modern technology, giving us the ability to pinpoint the exact location of objects, vehicles, or even people in real-time. But how do they communicate this invaluable data to us?

At their core, GPS trackers determine their location using signals from satellites orbiting the Earth. Once they acquire this data, the next challenge is transmitting it to servers or other devices where it can be accessed and analysed. This is where the SIM card comes into play.

Much like how our mobile phones require SIM cards to connect to cellular networks and communicate with others, GPS trackers need them for similar reasons. The sim card for a gps tracker is not just a supplementary component; it’s an essential piece of the puzzle. It facilitates the constant connection to the internet, allowing the device to send real-time or periodic location updates.

Without a SIM card, the tracker might still acquire its location, but it would be like a phone without a signal – unable to communicate its findings to the outside world. Therefore, the SIM card acts as the tracker’s communication bridge, linking the isolated data points it gathers to a broader network where it becomes actionable intelligence.

Diving into the Types of SIM Cards: M2M vs. IoT

There’s a plethora of SIM card types in the market today, but two particularly stand out for GPS trackers – the M2M (Machine-to-Machine) and IoT (Internet of Things) SIM cards. Both are often used interchangeably, but they predominantly cater to devices requiring regular data exchanges over cellular networks. Their longevity since their inception in 1991 underscores their reliability and effectiveness.

What Sets Apart IoT SIMs from Standard Mobile SIM Cards

The resilience of IoT SIMs, even in extreme conditions, differentiates them from standard mobile SIMs. These cards are equipped for remote management, allowing bulk activation, control, and monitoring, all of which are paramount for large-scale GPS tracking solutions. Moreover, with features like fixed IP addresses and support for data plan aggregations, IoT SIMs provide a more robust, reliable, and economical solution for GPS tracker sellers.

The Role of Access Point Name (APN) in GPS Tracking

Acting as an intermediary, the APN connects the GPS trackers to a specific network. To ensure flawless data transmission, the tracker’s APN settings must align with those of the telecom operator. Typically, these configurations are executed via SMS commands, as outlined in the device’s user manual. Correct APN setup is a cornerstone for the tracker’s optimal performance.

Border Crossings: APN Setting Challenges

For global wanderers relying on their GPS tracking devices, transitioning across international borders might present challenges with APN settings. Traditional GPS trackers, which are bound to the APN settings of specific telecom operators in each country, often require manual reconfiguration to adapt to the local cellular network. This not only poses an inconvenience but also leaves room for potential mishaps in connectivity.

Moreover, it’s not just about ensuring connectivity; there’s also the critical aspect of roaming charges. When your GPS device communicates data in a foreign land, it might incur additional costs if your SIM doesn’t have favorable international plans or partnerships.

However, the tech landscape is evolving rapidly. Nowadays, advanced IoT SIM cards offer a seamless solution to these challenges. These SIMs are equipped with the capability to work on a single APN, regardless of the country or network. This means that the SIM can automatically switch networks based on signal strength and regional availability without needing any manual intervention. This not only assures consistent connectivity but also optimizes the connection based on local network performance.

Such innovations are game-changers for those who need reliable GPS tracking across multiple countries without the hassle of constantly adjusting settings or fearing unexpected charges. Always choose a GPS solution keeping in mind both your immediate and potential future needs, ensuring that technology serves as an enabler rather than a hindrance in your journeys.

Where to Buy SIM Card for GPS Tracker

While several platforms, including Amazon, eBay, AliExpress, and Alibaba, offer IoT SIM cards, always opt for credible sources or directly from renowned GPS tracker sellers. Some vendors, such as Skywonder, even offer devices with pre-inserted IoT SIM cards, ensuring a hassle-free gps tracking solution right out of the box.

How to Activate SIM Card for GPS Tracker

Activation typically involves a series of steps detailed in the tracker’s user guide. It may involve sending specific SMS commands to the SIM card’s number. For a comprehensive setup, consult with the seller or the manufacturer directly.


  1. How much data does a GPS tracker use?

   Typically, the data consumption depends on the frequency of updates, type of data transmitted, network protocol, and encoding efficiency. Check the device’s specifications or consult the manufacturer for precise figures.

  1. What kind of sim card do I need for a gps tracker?

   Ideally, M2M or IoT SIM cards are recommended due to their longevity and adaptability in diverse environments.

  1. Does the SIM card’s mobile operator matter?

   Yes. Different operators may have distinct APN settings. It’s crucial to configure these correctly for uninterrupted tracking.

  1. Can I use my regular mobile SIM card for a GPS tracker?

   While it’s technically possible, IoT or M2M SIM cards are specifically tailored for devices like GPS trackers, offering superior reliability and data transmission capabilities.

  1. How do I deal with potential roaming charges when travelling across borders?

   Always check the roaming policies of your SIM card provider. Some might offer packages or plans designed for cross-border use.

  1. Do all GPS trackers require a SIM card?

   Not all, but most GPS trackers, especially those transmitting data over cellular networks, require a SIM card for operation.
