Notes:

• If a GPRS PPP session is already running, the setting of a CSD (GSM data call) is not

supported.

• For an international number, the local international prefix does not need to be set

(usually 00) but must be replaced by the ‘+’ character.

• Note that some countries may have specific numbering rules for their GSM handset

numbering.

• When the FDN phonebook has been activated (see +CLCK command), only numbers

beginning with the digits of FDN phonebook entries can be called. For example, if

“014629” is entered in the FDN phonebook all the phone numbers beginning with these

6 digits can be called.

• An outgoing call attempt can be refused if the AOC service is active and credit has

expired (NO CARRIER).

• As per GSM 02.30, GSM sequences may be controlled using dial commands. These

sequences can contain “*”, “#”, but “;” is forbidden in the sequence. For example, to

invoke or suppress CLIR service temporally, ATD*31#<nb>[;] and ATD#31#<nb>[;] can

be used (with ‘;’ at the end, a voice call will be launched).

• If the FDN phonebook is activated, the call forwarding sequences are allowed only if

they are present in the FDN.
