Every day, thousands of satellites are busy pinpointing exact locations across the world with maximum accuracy. How can we use this technology to enhance our day to day lives?

Enter Smart SIMs for connectivity.


What is a Smart SIM?

If you thought SIMs were just for phones, think again. While different from a phone’s SIM, a Smart SIM is a small chip with big ideas. It’s specially designed to work with smart tech devices, enabling the ability to send and receive updates with other devices and connecting it to the internet.  GPS works by sending signals between devices and satellites. Unlike Bluetooth alone, our Designed & Connected by Vodafone devices such as the Curve Smart GPS Tracker and the Curve Bike light & GPS tracker, use a super-smart combo of GPS, Bluetooth, Cellular and Wi-Fi sniffing to pinpoint the device’s location.

You can track your valuables and have peace of mind when you’re far away. Choosing a GPS tracker with a SIM card means you can stay connected with your things, even when you’re apart.


How does a Smart SIM work in a GPS tracker?

If you purchase Curve, the Smart GPS Tracker, there’s a built-in Smart SIM that’s connected to our global network and is ready to go when you are. Information is delivered to your phone, making staying connected convenient. Simply download the Vodafone Smart App and activate the SIM connectivity plan that works for you.


Why does a GPS tracker need a Smart SIM card?

If your phone is wedged between the car seat or your keys have inexplicably turned up in the fridge, Bluetooth-only trackers are great. But they have a limited range. With a Smart SIM, you get location updates to your smartphone from a distance or when you’re far away.
