Chapter 3 – Supported GSM/WCDMA AT Commands

High Speed HSPA-H4 AT Commands Reference Guide (Document S000483A) 126

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.
