Hey there @Mel146.
Welcome to the EE Community 😊
As your network provider, I'm afraid we don't have any way of tracking the location of handsets.
If it's lost or stolen though, we definitely want to help you with making sure this gets reported, and there are a few other ways you may be able to track it too.
What exactly has happened here?
Also if it was an iPhone, you can try tracking this over at Find Devices - Apple iCloud.
