Reference Note GSM 07. 07 · Caution: After entering a password with AT+CPIN all other commands that need access to data on the SIM card may be blocked for up to 20 seconds. The response in these cases will be "+CME Error: 14" (SIM busy). · Successful PIN authentication only confirms that the entered PIN was recognized and correct. The output of the result code OK does not necessarily imply that the mobile is registered to the desired network. Page 118 of 257 10. 01. 2003 TC35i_ATC_V00. 01 TC35i AT Command Set PRELIMINARY Typical example: PIN was entered and accepted with OK, but the ME fails to register to the network. This may be due to missing network coverage, denied network access with currently used SIM card, no valid roaming agreement between home network and currently available operators etc. TC35i offers various options to verify the present status of network registration: For example, the AT+COPS?(Chapter 4. 30) command indicates the currently used network. With AT+CREG (Chapter 4. 41) you can also check the current status and activate an unsolicited result code which appears whenever the status of the network registration changes (e. g. when the ME is powered up, or when the network cell changes). Wait 10 seconds after PIN input before using SMS related commands. <pin> and <new pin> can also be entered in quotation marks (e. g. To check the number of remaining attempts to enter the passwords use the AT^SPIC command. See also Chapter 8. 2 "Summary of PIN requiring AT Commands". See Chapters 4. 38 and 7. 42 for information on passwords. · · · · · TC35i_ATC_V00. 01 Page 119 of 257 10. 01. 2003 TC35i AT Command Set PRELIMINARY 4. 35. 1 What to do if PIN or password authentication fails? PIN1 / PUK1: After three failures to enter PIN1, the SIM card is blocked (except for emergency calls). To unblock the SIM card, the client needs to enter the associated PUK (= PIN Unblocking Key / Personal Unblocking Key). After ten failed attempts to enter the PUK, the SIM card will be invalidated and no longer operable. In such a case, the card needs to be replaced. PIN1 consists of 4 to 8 digits, PUK1 is an 8-digit code only. To unblock a disabled PIN1 you have three options: § You can enter AT+CPIN=PUK1, new PIN1. § You can enter AT+CPWD="SC", PUK1, new PIN1. § You can use the ATD command followed by the GSM code **05*PUK*newPIN*newPIN#;. PIN2 allows access to the features listed in Chapter 4. 36. [. . . ] + PAD 20 All Services --T = time in seconds In contrast to AT command AT+CCFC, parameter T has no default value. If T is not specified, an operator defined default or the last known value may be used, depending on the network operator. PW = Password C = character of TE character set (e. g. asterix, hash or digit in case of USSD, or digits in case of held calls or multiparty calls) Possible responses <m> Mode: 0 = not active, 1 = active <n> Unsolicited result code: 0 = presentation disabled, 1 = presentation enabled <status> Status: 0 = not active, 1 = active <class> Represents BS = basic service See Chapters 4. 6 (AT+CCFC), 4. 21 (AT+CLCK) and 8. 4. 1.
