Inserting the SIM card and battery
Your SIM card contains account
information such as your phone number
and voicemail access number. To use your
Treo750 smart device’s phone, email, or
web features, you need to insert a SIM
card. If a SIM card is not included in your
Treo750 box, Cingular will provide you with
one.

door release button, and use your other
hand to slide the battery door
downward to remove it from your

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
Treo750.
