If the user tries to do something which requires PIN2 (CHV2), the product will refuse
the action with a “+CME ERROR: 17” (SIM PIN2 required). The product then waits for
SIM PIN2 to be given. Of course, if SIM PIN2 is blocked, SIM PUK2 is required instead of
SIM PIN2. For example, the product needs PIN2 to write in the fixed dialling phonebook
(FDN), so if SIM PIN2 authentication has not been performed during the current session,
SIM PIN2 is required.
