What does "WIND: 11" mean?

Couldn´t find “WIND: 11” meaning.

Where can I find those informations?

Best Regards,


The answer is in the AT Commands Interface Guide.

Check the chapter General Indications +WIND.

“+WIND: 11” is the indication showing the checksum of the SIM card phonebooks.

This allows you to detect if one or more phonebook entries have been changed (with another phone for example).
