Telia Mobile certificate Instructions

Activating and using the Mobile certificate is free of charge for our subscription customers within Finland.

When abroad, the use of the service is charged according to the international SMS pricing (in Finnish). In practice it means that using Mobile certificate involves receiving one message and sending between 1 to 3 messages.

Requirements for having Telia Mobile certificate

• Minimum age of 13 years.
• A Finnish personal identity code (HETU). The electronic identification code (SATU) used in the Mobile certificate requires that the personal identity code is registered in Finland’s Population Information System.
• A SIM card that supports Mobile certificate (the card has an eID identifier) or an eSIM. If your current SIM does not have this function, order a new one (in Finnish).
• Your identity must be reliably verified in the activation by using strong electronic identification. You can authenticate, for example, with Finnish online banking credentials (TUPAS) or an electronic ID card granted by the police.

Note before activation

• Be especially careful to ensure that your mobile phone and Mobile certificate PIN are not accessible to others.
• When ordering Mobile certificate, a customer relationship is established between you and Telia, if one does not already exist.

How to activate Mobile certificate

Here’s a walkthrough of the activation path. The path is in Finnish only.

Mobile certificate is valid for 5 years at a time. An expiring or already expired certificate must be re-registered.

We will notify you approximately 30 days before the expiration via a text message from a short number 50101. If the certificate expires, we will inform you about it via a text message from the same number.

We recommend re-registering the certificate as soon as you receive the first notification, as this allows you to complete the process using your current Mobile certificate. If the certificate has expired, re-registration must be done using online banking credentials.

Re-register your certificate (in Finnish) 

You can terminate your Mobile certificate subscription by contacting our customer service.

If you want, you can set an anti-spamming code for your Mobile certificate. This feature helps protect you from fraud and ensures that no identification requests are sent to your phone if, for example, someone accidentally enters your phone number when using Mobile certificate.

The anti-spamming code is a password of your choice that must be entered along with your phone number during identification. When the anti-spamming code is enabled, the identification window will ask for the code after entering the phone number. Only then will the identification request be sent to your phone.

Managing the anti-spamming code via SMS (to number 15011):

• To enable the anti-spamming code for the first time, send a message: ESTO and the password you chose (e.g., “ESTO veturi1”). The code must be 3–10 characters long, contain only letters and numbers, start with a letter, and must not include special characters like ä, ö, or å.
• To disable the feature, send “ESTO 0”
• To re-enable the feature, send just “ESTO”
• To change the code, send “ESTO newpassword” (e.g., ESTO ratikka2)

Sometimes, such as when changing your SIM card, Mobile Certificate needs to be re-registered. Below are solutions to the most common Mobile certificate issues.

Did you forget your PIN and the certificate got locked?

No worries! If you forgot your Mobile certificate PIN and the certificate is now locked, simply re-register it by using your online banking credentials to regain access.

What personal data is shared during identification or signing?

Your full name (first and last names) and SATU (electronic identification code) are securely and confidentially shared with the service provider. In some cases, your personal identity code (HETU) may also be shared. Before entering your PIN, your phone will display the data being shared. You can cancel the process if you wish.

How do I change Mobile certificate PIN?

This depends on your phone model:

• iPhone: Settings > Mobile Data > SIM Applications > Mobile Certificate
