Inserting and removing the SIM
Your phone needs a valid SIM card to work (…To keep it simple, we’ll just
call it ‘SIM’ from now on). Your network connection data and your SIM
address book are saved on the SIM. So, to avoid damaging your SIM or
losing data, try not to touch the metal surface when you’re handling it – and
keep well away from any magnetic or electric source.
here’s what you do…
1.
Switch off your phone and disconnect any external power.
2.
Remove the back cover and then the battery.
3.
Hold your SIM on the cut corner, and slide it
– face down – into the card holder.
4.
Insert the battery.
5.
Replace the back cover.
