Insert the SIM and memory cards
Insert the cards
- Open the SIM and memory 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 dual-SIM phone, put the second SIM in the SIM2 slot.
- If you have a memory card, put it in the memory card slot.
- Slide the tray back in.
Use only original nano-SIM cards. Use of incompatible SIM cards may damage the card or the device, and may corrupt data stored on the card.
Both SIM cards are available at the same time when the device is not being used, but while one SIM card is active, for example, making a call, the other may be unavailable.
Use only compatible memory cards approved for use with this device. Incompatible cards may damage the card and the device and corrupt data stored on the card.
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.
Note: If you have a dual SIM phone with only one SIM tray, you cannot use two SIM cards and a memory card at the same time.
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.
Note: Pre-installed system software and apps use a significant part of memory space.
