To change your SIM card, you will need a SIM tool (small metal pin).
Find the small hole on the side of your device and use this pin to pop your SIM card tray out. Place your SIM card chip-side down onto the tray and slide the tray back into your mobile phone. When you turn your phone on, your phone will recognise that this is a new SIM and prompt you to set it up.
