No SIM card: You need to insert SIM card into the W406, or your SIM card may not be inserted
correctly.

section.

Enabling or Disabling the PIN Code Authentication
You can enable PIN code authentication to prompt for PIN code authentication whenever the
W406 boots up.
Use the sim_enable_pin –e –p PIN code command to enable PIN code authentication. For
example, enter sim_enable_ping –e –p 0000 to activate PIN code authentication.
