may take a while before the on-screen charging indicator
starts scrolling.

the device screen will stop scrolling horizontally. Once charging
is complete, disconnect the charger from the device, and then
from the wall outlet.
SIM card information

Be careful to handle, insert or remove the SIM card since the SIM card

always make sure that the phone is switched off.
