Note:
• 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.
16.3 AT+CPBR Read from Phonebook
Description: AT+CPBR serves to read one or more entries from the phonebook selected with
AT+CPBS.
The test command returns the location range supported by the current phonebook
storage, the maximum length of <number> field and the maximum length of <text> field.
Length information may not be available while SIM storage is selected. If storage does not
offer format information, the format list contains empty parenthesizes.
The write command determines the phonebook entry to be displayed with <location1> or
a location range from <location1> to <location2>. Hence, if no <location2> is given only
the entry at <location1> will be displayed. If no entries are found at the selected location
“OK” will be returned.
Test Command Syntax: AT+CPBR=?
Response: +CPBR: (1-<maxloc>), <nlength>, <tlength>
OK
+CME ERROR
Write Command Syntax: AT+CPBR=<location1>[, <location2>]
Response: [+CPBR: <location1>, <number>, <type>, <text>]
[+CPBR: <location2>, <number>, <type>, <text>]
