Open the SIM card tray: push the tray opener pin into the tray hole and slide the tray out.
If you have a single-SIM phone, put a nano-SIM card in slot 1 and a memory card in slot 2 on the tray, with the contact areas face down. If you have a dual-SIM phone, put a nano-SIM card in slot 1 and either a second SIM or a memory card in slot 2, with the contact areas face down.
Slide the tray back in.
Tip: To find out if your phone can use 2 SIM cards, see the label on the sales box. If there are 2 IMEI codes on the label, you have a dual-SIM phone.
Important: Do not remove the memory card when an app is using it. Doing so may damage the memory card and the device and corrupt data stored on the card.
Tip: Use a fast microSD memory card (up to 512 GB) from a well-known manufacturer.
