1. Insert the SIM and memory 
card
1. Open the SIM card tray: push the tray opener pin 
in the tray hole and slide the tray out.
2. Put the nano-SIM in the SIM slot on the tray with 
the contact area face down. 
3. If you have a memory card, put it in the memory 
card slot.
4. 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: 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.
2. Charge the battery and switch 
the phone on
Plug a compatible charger into a wall outlet, and 
connect the cable to your phone. Your phone 
supports the USB-C cable. You can also charge your 
phone from a computer with a USB cable, but it may 
take a longer time.
If the battery is completely discharged, it may take 
several minutes before the charging indicator is 
displayed.
To switch your phone on, press and hold the power 
key until the phone vibrates. The phone guides you 
through the setup.
