I have problems turning on my Apple iPhone X

Connect the charger to the socket and to a wall socket.

When the battery charging icon is displayed, charging is in progress.

When the phone is turned on, you can always see the battery power level. The larger the coloured section of the battery icon, the more remaining battery power.

Press and hold the Side button until your phone is turned on.

Slide your finger upwards starting from the bottom of the screen.

Press SIM Card.

Key in your SIM PIN and press OK. The default SIM PIN is 0000.

If an incorrect SIM PIN is entered three times in a row, your SIM will be blocked. To unblock your SIM, you'll need to key in your PUK. O2’s help guide will tell you how to get your PUK. Please note: If you key in the wrong PUK ten times in a row, your SIM will be blocked permanently. In this case, you need a new SIM from O2.

Press the Top volume key.

At the same time, press and hold the Side button until the power off icon is displayed.

Press and drag the power off icon right.
