Position the SIM card with its gold-contacts facing down. (There is a symbol of SIM Card
with its arrow on the front panel. It will ensure the correct orientation of the SIM Card when
it is being inserted. )
Push the SIM card gently until it is being clicked and locked in place. A screwdriver can
help to push the SIM card if the SIM card cannot be inserted properly.
