Network 2 SIM Pin Settings
The SIM PIN is a 4 digit numeric code used to unlock the SIM card. This allows m obile devices to
gain access to network specific information stored on the SIM. If the SIM PIN f unctionality is
enabled on the SIM card, Network Registration will not start until after a valid PIN number has
been configured. This is for both the GSM and and GPRS networks. Typically SIM cards are
delivered from the provider with SIM PIN function disabled.
Upon 3 failed consecutive attempts to enter a pin, your SIM card will be locked (old PIN will
become invalid). To unlock the SIM card, you will have to contact the provider of the SIM card and
request a PIN Unlock (PUK) code. Use this with extreme caution, becaus e 10 failed PUK
attempts will lock the SIM forever!
The table below shows the settings for SIM PIN configuratio n.
