Insert the SIM and memory cards
Insert the cards
- Open the SIM card tray: push the tray opener pin in the tray hole and slide the tray out.
- Put the nano-SIM in the SIM slot on the tray with the contact area face down.
- If you have a second SIM, put it in the SIM2 slot.
- If you have a memory card, put it in the memory card slot.
- Slide the tray back in.
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, up to 256 GB microSD memory card from a well-known manufacturer.
