Troubleshooting
The following refer to specific problems:
Has the phone
been damaged,
dropped, or
gotten wet?
Dropping your phone, getting it wet,
or using a non-Siemens battery
charger can damage the phone. The
phone’s limited warranty does not
cover liquid damage or damage
caused from using non-Siemens
accessories.
Was a
non-Siemens
battery charger
used?
Problem
Solution
My phone was
stolen. To whom
should I report
this?
Report a stolen phone to the police
and to your service provider (the
company that sends you your
monthly wireless service bill).
I forgot my
password.
See page 44.
I pressed the
end/power key,
but nothing
happened.
Be sure to press and hold
O
(the
end/power key) until the display
appears and you hear an audible
alert (this could take a couple of
seconds). If nothing happens, check
that the battery is charged (see
page 16).
The display
says:
Insert SIM Card
or
Check SIM Card
even though I
have inserted my
SIM card in the
phone.
The SIM card may be incorrectly
inserted. Check the SIM card to make
sure that it is inserted properly (see
page 14).
Note:
Be sure to turn your phone off
and then back on after you re-insert
the SIM card.
