Confidential / Released

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 registra-
tion: 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. ”1234”).
· To check the number of remaining attempts to enter the passwords use the
AT^SPIC command. See Chapter 7.38.
· See also Chapter 8.2 “Summary of PIN requiring AT Commands“.
· See Chapters 4.38 and 7.42 for information on passwords.
