Using a Memory Card
Your i870 phone comes with a memory card,
memory card reader, and memory card adaptor.
For complete instructions on using the memory
card with your phone and with your computer, see
“Using a Memory Card” on page 111.
* Depending on your service provider, the memory card, memory
card adaptor, and memory card reader may not be include with
your phone. Your i870 phone can be used with a Transflash or
MicroSD memory card.
SIM Card Security
Your SIM card protects your personal information.
The SIM card stores all your Contacts information.
Since this information is stored on your SIM card,
not in your phone, you can remove the information
by removing your SIM card.
Note: Except for making emergency calls, your
phone will not function without the SIM
card.
To prevent unauthorized use of your phone, your
SIM card may be protected by a PIN that you enter
each time the phone is powered on. You can
change the PIN or turn off the requirement that it
be entered.
