Inserting the SIM
card and battery
Your SIM card contains account
information such as your phone number
and voicemail access number. To use the
phone, email, or web features, the SIM
card must be inserted into your Centro.
NOTE Your SIM card may already be
installed in your Centro. Follow steps 1
through 3 to check. If a SIM card did not
come with your Centro, you may already
have one. If the SIM card does not work,
contact AT&T.
1 Press the battery door near the top and
slide the battery door downward to
remove it from your Centro.
2 If the battery is installed, remove it.
(See Replacing the battery for details.)
DID YOU KNOW ? The Ringer switch silences all
sounds at once. You don’t need to hunt for Off
buttons all over the device.
