SIM PIN Programming
The mini-SIM may require entry of a Personal Identification Number
(PIN)
. The PIN
is a four- to eight-digit number provided with the SIM card. If the service provider has
set the SIM to require PIN entry, the Phonecell will request the PIN each time it is
powered ON or the SIM is removed and replaced. The PIN can be stored within the
Phonecell for automatic entry when required. To use the automatic PIN entry feature,
the PIN must be correctly programmed and automatic PIN entry must be enabled.
If PIN entry is requested while automatic PIN entry is disabled, the Phonecell emits
a SIM Inactive tone. The SIM PIN can be manually entered at that time by dialing
the PIN and pressing #. If entry is successful, the SIM Inactive tone will be replaced
by service dial tone.
How to Enable/Disable the Automatic PIN Entry Feature
1)
Using a POTS
(Plain Old Telephone Set)
phone connected to the telephone port,
lift up the handset
(take off-hook)
.
NOTE: You must have tone-dial (DTMF) capability to enable/disable the
Automatic PIN Entry Feature.
2)
Enter the Programming mode:
Press:
#
*
0
*
1 2 3 4 5 6 7 8 #
The dial tone will cease upon entry of the first digit. If you enter the access code
correctly, the dial tone should change to a different, steady Programming tone
and the bottom LED indicator on the front of the Phonecell will blink alternately
RED and GREEN to indicate that you’re in the programming mode.
3)
. Once in Programming mode:
Press:
#
*
65
*
< auto_PIN>
*
<PIN> #
• To disable automatic PIN entry, set the "auto PIN" value to
0
.
• To enable automatic PIN entry, set the "auto PIN" value to
1
.
You must enter either
0
or
1
, otherwise, the FWT will not update or store this
value and the existing stored parameter will remain. The factory default value is
0 (disabled)
. The factory default PIN setting within the FWT’s non-volatile
memory is "
1234.
"
4)
Correct entry will be confirmed by the return of the programming tone, which
signifies that the unit is ready to accept the next entry. Incorrect entry will result in
a short, three tone sequence of rising frequencies, followed by the return of the
programming tone, which again signifies that the unit is ready to accept the
corrected entry.
5)
Hang up the telephone handset (place on-hook).
For Example: To enable automatic PIN entry for PIN "1234,"
dial: #
*
65
*
1
*
1234 #
IMPORTANT!
Automatic PIN entry must be disabled before the SIM is changed (including
initial entry) so that the PIN for the new SIM card can be entered correctly
before the GSM module requests the PIN.
