PIN Codes (PIN1 and PIN2)

5G Xi "crossy" FOMA

You can set two PIN codes on the docomo UIM Card (FOMA Card) for your FOMA handset, the PIN1 code and PIN2 code. The PIN1 code is used to prevent others from gaining unauthorized access to your mobile phone handset. PIN1 is a four- to eight-digit number (code) to verify the handset user and must be entered every time you insert the docomo UIM Card (FOMA Card) into the FOMA/Xi "crossy" handset or turn on the FOMA/Xi "crossy" handset power.
Entering the PIN1 code allows you to make and receive calls and use handset functions. The PIN2 code is a four- to eight-digit password that you enter when using or requesting user certificates or performing tasks such as resetting total call charges.

  • With some smartphone models, you will be requested to input a PIN code when you cancel airplane mode. The PIN code input screen does not appear when you insert the docomo UIM Card (FOMA Card) into the handset or turn on the power.

Using your PIN1 code

When the PIN1 code ON/OFF setting is set to ON, you are required to enter the PIN1 code when you turn on the handset power. If you enter the PIN1 code incorrectly, you will not be able to make or receive calls or use various communications functions. If the wrong PIN1 code is entered three times in a row, PIN Lock will be automatically activated.
