terminal. It is held in the logic circuit of the main board itself. If the main board is changed then IMEI will
change.

For example, in J07, J stands for 2000 and 07 for July (12 for december).

2.d SIM Latching

SIM Lock consists in restricting the use of the terminal to a family of SIM cards. For the SIM Lock, three sets
of information are used. This information is read from data fields in the SIM card.

1°) IMSI (International Mobile Subscriber Identity), 15 Digits :

Example of IMSI : 208 01 55 12312312
208 = MCC = Mobile Country Code (ex : 208 for France)
01 = MNC = Network Country Code (ex : 01 for FT)
55 = NS = Network Subset
12312312 = serial number

2°) Group IDentifier 1 (GID1):

This data field can contain digits or letters which identify a family of SIM
Ex : XX for a type for of prepaid SIM card of Service provider Y

3°) Group IDentifier 2 (GID2) :

Same as GID1 to identify a sub family of SIM.

Then, from this information, we have 5 types of latch :

1°) Network Level :

Latch on MCC MNC of IMSI of the SIM only
(ex : only the cards 208 01 are able to operate the mobile.
Mitsubishi calls this latch NCK (NCK stands for “ Network Control Keys” and is the password to lock
the mobile at the network level)

2°) Network Subset Level :

Latch on MCC, MNC and digit 6 and 7 of the IMSI
Ex : latch on 208 01 55, only the SIM cards with an IMSI starting with 208 01 55 will operate the
mobile.
Mitsubishi calls this latch NSCK (“Network Subset Control Key”)

3°) Service provider level :

Latch on Network (value of MCC MNC) and value of GID1 data field.
Ex : latch on the value “XX” in GID1 and MCC MNC=208 01, only the SIM cards of service provider
Y with XX stored in data field GID1 will operate the mobile.
Mitsubishi calls this latch SPCK (Service Provider Control Key)

4°) Corporate Provider Level :

Latch on network (value of MCC and MNC) and a value stored in GID2
Mitsubishi calls this latch CPCK (Corporate Provider Control Key)

5°) IMSI level:

Latch on the complete IMSI of one SIM card.
Only one SIM card corresponding to the correct IMSI operates the mobile. Usually, this latch is done
automatic (the first SIM card inserted in the mobile is the only SIM which can be used by this
mobile).

General information :

To lock /unlock a mobile, you need an 8 digit password for each level concerned, and each mobile (one
set of passwords for one IMEI). These passwords are calculated with a special algorithm. You have
only 10 attempts to unlock a mobile. After 10 unsuccessful attempt, the mobile is permanently blocked.
To enter the unlock procedure, you need to access special menus with specific access codes.
