  • How Mobiil-ID works

    Mobiil-ID is a digital identity document on your mobile phone. If you have concluded a Mobiil-ID Agreement, you will receive a new SIM card along with your Mobiil-ID PIN codes.

    Codes necessary for using Mobiil-ID:

    • Mobiil-ID PIN1 code – for identification;
    • Mobiil-ID PIN2 code – for providing a digital signature;
    • Mobiil-ID PUK code – for unlocking locked PIN codes.

    Using Mobiil-ID:

    Mobiil-ID enables you to access e-services and provide digital signatures.

    Step 1: Select “Mobiil-ID” and enter the requested information (personal identification code / phone number / user ID).

    Step 2: the control code of the service is displayed on the screen and sent to you as a text message. Make sure the codes are identical!

     Step 3: Authentication/Digital signing:

  • Secure use of Mobiil-ID

    Similarly to using an ID card, the best practice of secure use must also be followed when using Mobiil-ID:

    • In order to ensure security, keep the Mobiil-ID PIN and PUK codes separately from the mobile phone and avoid other persons getting hold of the codes.
    • Do not scratch the PIN codes before you need them.
    • Scratch the PUK code only if you need it to unlock the PIN codes.
    • Do not use simple combinations (e.g. 0000, 1111, 1234, 2580, etc.) or your birth date, house or apartment number, etc. as your PIN codes.
    • If possible, change your Mobiil-ID PIN codes immediately after activating your Mobiil-ID.
    • If you lend your mobile phone to other persons, you must not reveal the PIN or PUK codes of your Mobiil-ID.

    Always remember that the digital signature you give using Mobiil-ID is equal to a handwritten signature, just like the digital signature you give with an ID card.

    In case you lose your mobile phone and/or SIM card, notify the mobile operator immediately by calling the customer service number of the mobile operator or visit their nearest store. The SIM card will be disabled, i.e. the use of your Mobiil-ID will be suspended.

    In case you entered the PIN code of your Mobiil-ID incorrectly for 3 times and it was locked, go to Mobiil-ID menu section “Cancel the block” and enter the PUK code.

    In case you entered the PUK code of your Mobiil-ID incorrectly for 3 times and Mobiil-ID was locked, consult your mobile operator, who will issue you a new SIM card.
