SIM Authentication

If the PUK is correct and the new PIN codes agree, you will hear the normal

dial tone, which indicates that the voice service is activated and that it is

possible to make phone calls. Remember the new PIN for future use.

If the PUK is incorrect or the new PIN codes do not agree, you will hear the

“PUK required” tone again. Repeat the “unblock SIM card” sequence

above.

Note: If ten attempts have been made with an incorrect PUK, the SIM

card is permanently blocked and a new SIM card is required.

Contact your service provider.

3.1 Information Tones

The Ericsson W25 generates information tones in your telephone handset,

thus providing the same characteristics as the one given by the traditional

fixed line network.

The following table describes the nature of the unique information tones

you will get when using the Ericsson W25.
