The response "+CME ERROR: 13" (SIM failure) is returned after 10 unsuccessful PUK
attempts. The SIM card is then out of order and must be replaced.
If the user tries to do something which requires PIN 2/CHV 2, the product will refuse
the action with a "+CME ERROR: 17" (SIM PIN2 required). The product then waits for
SIM PIN 2/CHV 2 to be given.
If PIN 2/CHV 2 is blocked, SIM PUK2 is required instead of SIM PIN 2/CHV 2.
For example, the product needs PIN 2/CHV 2 to write in the fixed dialing phonebook
(FDN) , so if SIM PIN 2/CHV 2 authentication has not been performed during the
current session, SIM PIN 2/CHV 2 is required
