Fixed dialling
The fixed dialling function allows calls to
be made only to certain numbers saved on
the SIM card. Fixed dialling requires a SIM
card that allows fixed numbers to be saved.
The fixed numbers are protected by your PIN2.
Note: Calls to the international emergency number
112 can still be made, even when the fixed dialling
function is on.
Partial numbers can be saved. For example, saving
0123456 allows calls to be made to all numbers
starting with 0123456.
Numbers with question marks can be saved. For
example, saving 01234567?0, allows calls to be
made to numbers from 0123456700 to 0123456790.
To enter a question mark, press and hold .
