Getting started

Installing the nano-SIM card/microSDXC™ card

The nano-SIM card and the microSDXC card (sold separately) can be installed or removed while the phone is turned on. You need to unmount the microSDXC card before removing it. (See Connecting

to networks and devices – Using the microSDXC card as portable or internalstorage.)

Note: Your phone will come with the nano-SIM card already installed.

Warning! To avoid damage to the phone, do not use any other kind of SIM card or any nonstandard nano-SIM card cut from a SIM card. You can get a standard nano-SIM card from your service provider.

Insert the tray eject tool into the hole on the

nano-SIM/microSDXC card tray, and pull the tray out.

Place the nano-SIM card and microSDXC card on the tray with the gold-colored contacts facing down.

Carefully slide the tray back into place.

Charging the battery

Your phone’s battery should have enough power for the phone to turn on, find a signal, and make a few calls. You should fully charge the battery as soon as possible.

If the battery is low, there will be a pop-up message on the screen. As you charge your phone, the screen will tell you the exact battery level each time you wake up your phone.

Warnings!

Connect the adapter to the charging/USB Type-C

port.
