Brief format of the phone book (ADN) in the SIM card

ADN format

ADN is stored in 3f00/7f10/6f3a under the SIM card. The record format is 14 at the minimum, and the maximum value is 255 (?), The maximum number of records is 255 (?)

The last 14 bytes are mandatory. The first 12 bytes are phone numbers, the last is ext1, and the last is ccp1.

If the length is more than 14, the name of the user stored in the front is stored. If it starts with 80, 81, and 82, the name is in ucs2 format; otherwise, the name is in English format.

Example.
