List of AT Commands for Nokia 22
Copyright © Nokia Mobile Phones 2001. All rights reserved.
<format>:
2 numeric <oper>
<oper> The numeric format is the GSM Location Area Identification number (refer GSM 04.08
10.5.1.3) which consists of a three BCD digit country code coded as in ITU-T E.212
Annex A, plus a two BCD digit network code, which is administration specific;
returned <oper> shall not be in Binary Coded Decimal (BCD) format, but in IRA
characters converted from BCD; hence the number has the following structure:
(country code digit 3)(country code digit 2)(country code digit 1)(network code digit
2)(network code digit 1)

Test
+CLCK=? +CLCK: ("PS","SC","AO","OI","OX",
"AI","IR","AB","AG","AC","FD")
The +CLCK command enables and disables or queries the state of SIM/ME security features (PIN
or security code query or fixed dialling feature) or call barring supplementary services. The <fac>
values “AB”, “AG” and “AC” are only applicable for <mode>=0. Only security code levels ‘phone’
and ‘none’ can be handled with this command. If the ‘memory’ level is set and the status is queried
(+CLCK="PS",2), the AT interface shall indicate ‘not active’ (+CLCK: 0). When the SS status
request response coming from the network indicates that the SS is active for a specific data bearer
services (e.g. ‘circuit async’), the AT interface shall only indicate ‘data’ (<class>=2) (‘not active’
case is displayed only when the SS is not active to any service; i.e. +CLCK: 0,7).
The test command returns facility values supported by the Nokia 22 as a compound value.
Defined values
<fac>:
"PS" PH-SIM (lock Phone to SIM card) (The ME asks for a password when
an other SIM card than the current SIM card is inserted; the ME may
remember certain amount of previously used cards and, therefore, it
does not necessarily ask for a password when a previously used cards
is inserted)
