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, AT&T 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.

DID 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 AT&T
customer care at 1-866-246-4852 or dial 611
from your Treo 750.
