Chapter 15 – Phonebook Commands
Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 253
<nlength>
Maximum length of phone number for "normal" locations. Depending on the storage, a limited number of
locations with extended memory is available per phonebook. These locations allow storing numbers with twice
the standard length, which is 2*<nlength> digits for normal numbers, but only <nlength> digits for numbers saved
with parameter <type>= 209. If all extended locations of the selected phonebook are used up, then any attempt
to write a number which requires extended memory will be denied with CME ERROR: INVALID DIAL STRING.
<tlength>
Maximum length of <text> assigned to the telephone number. The value indicated by the test command is given
in octets. If the <text> string is given in GSM characters, each character corresponds to one octet. If the <text>
string is given in UCS2; the maximum number of characters depends on the coding scheme used for the alpha
field of the SIM. In the worst case the number of UCS2 characters is at least one less than half the number of
GSM characters.
Examples:
Example 1
Make a new phonebook entry at the first free location (here location 3)
AT^SPBW=,"[phone]",145,"international"
^SPBW: 3
Example 2
Delete entry at location 3
AT^SPBW=3
Example 3
The following examples are provided to illustrate the effect of writing phonebook entries with different
types of dial string modifiers in <number>.
AT^SPBW=5,"12345678",,"Arthur"
^SPBW: 5
AT^SPBW=6,"432!+-765()&54*654#",,"John"
^SPBW: 6
AT^SPBW=7,"432!+-765()&54*654#",129,"Eve"
^SPBW: 7
AT^SPBW=8,"432!+-765()&54*654#",145,"Tom"
^SPBW: 8
AT^SPBW=9,"432!+-765()&54*654#",209,"Richard"
^SPBW: 9
Example 4
Read phonebook entries from locations 5 - 9 via AT+CPBR
+CPBR:5,"12345678",129,"Arthur"
+CPBR:6,"432!+-765()&54*654#",209,"John"
+CPBR:7,"432+76554*654#",129,"Eve"
+CPBR:8,"+432+76554*654#",145,"Tom"
+CPBR:9,"432!+-765()&54*654#",209,"Richard"
Notes:
• Users should be aware that when using this AT command quickly after SIM PIN authentication the SIM data may
not yet be accessible, resulting in a short delay before the requested AT command response is returned. See
Section 20.1, Restricted access to SIM data after SIM PIN authentication for further detail.
• During AT^SPBW write command it is possible that in some cases returns "+CME ERROR: operation temporarily
not allowed". Use AT^SPBW write command again.
• This command is PIN protected.
• This command is supported in airplane mode.

Exec Command: AT^SDLD
