Frequently asked questions

Where do I find my PUK code?

If you enter the wrong PIN code three times in a row, your SIM card will be locked for safety reasons. In this case, your phone will ask you for an 8-digit PUK (Personal Unlocking Key) code.

You can check your PUK code by logging in Telia.fi with your mobile phone number. Use the top-right hand corner Login button.

If you’re a private customer, please login here.

If your mobile subscription has been locked and you have not created an account for your company-owned subscription, you cannot check your PUK code on Telia.fi.

In this case, you can:

  • call our Corporate Customer Service 020693693 (mobile call / local network charges apply). Ordering your code will result in a service fee of 9 €.
  • ask the person responsible for your company’s mobile subscriptions to check your PUK code on Corporate Portal.

NB! If the PUK code is entered wrong many times in a row, the SIM card cannot be used. Please refrain from entering any numbers into your device until you find out your PUK code.

Postpone the due date of an invoice

As Telia’s business customer, you can apply for an extended term of payment both for your mobile and your fixed network invoices.
By applying for an extension and paying your invoice within the term of payment you have agreed, you will avoid collection costs. Please note, however, that you will be charged interest for late payment as specified in the Interest Act for any invoices paid after the original due date until the invoice is paid.


You can make a payment agreement in three ways: 

•    Via self-service in Corporate Portal. No separate service charge is charged for this. 
•    By text message. A text message sent to accept a payment agreement costs €0.14 (VAT 0%). 
•    Through Customer Service. For an agreement made in this way, you will be charged a service charge of €9.00 (VAT 0%). 


In Corporate Portal, you can apply for an extended term of payment for your invoice easily and quickly via self-service. 
•    Log in to Corporate Portal
•    Go to the Invoicing section
•    Find and open the invoice whose due date you want to postpone
•    Select Postpone the due date, and you will be proposed a new due date.
•    You can also order a payment reminder to a mobile phone number of your choice.
•    Confirm the changes.

Apply for an extension in Corporate Portal


•    Write the message OSAMAKSU invoice number (e.g. OSAMAKSU 12345678910), if you want to pay the invoice in two instalments, or write MAKSUPÄIVÄ invoice number, if you want to postpone the due date. Send the message to 15400.
•    You will receive an agreement proposal and further instructions by return message.
•    You will not be charged a separate service charge for making a payment agreement by text message. The accept message (HYVÄKSY), however, costs €0.14 (VAT 0%).
•    Accept the agreement by sending the message HYVÄKSY to 15400 (€ 0.14, VAT 0%).
•    By return message, you will receive confirmation of the acceptance of the agreement and the information you need to pay the invoice.
NB: The service is only available for Telia’s mobile subscriptions.


•    The agreement is binding and enters into force when the customer accepts it. To cancel or make changes to the agreement, the customer must contact our Customer Service. 
•    The invoicing company is Telia Finland Oyj or one of its Group companies. The invoicing company has the right to approve or reject the customer’s payment agreement, at its discretion. An extended term of payment cannot be granted, for example, for the first invoice or if the customer has other unpaid invoices. 
•    The invoice must be paid on the agreed date of payment. No separate payment reminder will be sent to the customer. If the customer fails to make the payment, the service provider has the right to close the subscription and take action in accordance with the general delivery terms concerning the service. 
•    An interest for late payment according to the Interest Act will be invoiced for the unpaid amount from the due date of the invoice until the last instalment of the invoice is paid. The interest for late payment will be invoiced on the following invoice.

Email invoice

If you order an email invoice, you will be sent by email a link through which you can view your invoice in electronic format and pay it easily.

You can order an email invoice for a data connection, broadband, fixed-line phone or mobile phone invoice. 


•    You can conveniently save an invoice you have opened in PDF format to your computer. 
•    You can easily transfer the payment data by means of a virtual bar code to your company's online bank.
•    You can print the invoice, if necessary.


•    Any direct payment will remain unchanged.
•    Any call itemization related to the invoice will not be delivered with the email invoice for reasons of information security. 
•    Please ensure that the email box linked with the email invoice is not full, so that the invoice can be delivered. 
•    The link on the email invoice works for 20 clicks, but no longer than a year.
•    Any payment reminders will be sent in electronic format to the same email address as your email invoice.
