Inserting the SIM
card and battery
Your SIM card contains account
information such as your phone number
and voicemail access number. To use your
Treo 750 smart device’s phone, email, or
web features, you need to insert a SIM
card. If a SIM card is not included in your
Treo 750 box, Cingular will provide you with
one.
1 Use one hand to press the Battery
door release button, and use your other
hand to slide the battery door
downward to remove it from your
Treo 750.

YOU
KNOW
?
The Ringer switch silences all
sounds, including music, at once; you don’t
need to hunt for “off” or “mute” settings in
individual applications.
TIP
If you don’t have a SIM card, contact
Cingular customer care at 1-866-CINGULAR
(1-866-246-4852) or dial 611 from your
Treo 750.
