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.
