Insert the SIM and memory cards
Insert the SIM card
- Open the SIM card tray: push the tray opener pin in 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.
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.
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.
Important: 5G may not be available when two SIM cards are inserted in your phone. If you have two SIM cards inserted, both SIM cards support 4G/3G/2G. Download the software update when available to enable 5G/4G/3G/2G support for SIM1 and 4G/3G/2G support for SIM2 when two SIM cards are inserted.
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: 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.
Tip: Use a fast, up to 512 GB microSD memory card from a well-known manufacturer.
