Going abroad?

Here’s what you need to know

When you go abroad, you’ll be able to use your national bundle within the EU, for calling, SMS and mobile surfing. No more extra roaming costs, and your usage will be deducted from your national bundle. Outside the EU, special rates will apply.
Choose your type of SIM card below to get all the details.
Be careful: if you're on a boat or in a plane, you'll connect to a satellite.
Check our FAQ for more info about that.

  • My SIM card is lost or stolen. What now?

    In that case, you can block your current SIM card and request a new one. To do so, go to your SIM settings. You can also block your device here.

    Extra info
    If you request a new SIM card, it will be sent to you by regular mail free of charge. You will of course keep your phone number and your remaining calling credit. To block your device we need some extra information: what was the type of device; where did you lose your device (city); what was the time when you lost it (day and time) and what is the device's IMEI number? The IMEI number is stated on the packaging or purchase invoice of your device.

  • How do I activate my SIM card?
    1. Visit
    2. Enter the last four digits of your Mobile Vikings SIM card number.
    3. That's it!
      - Are you activating a completely new SIM card with a new number, or a replacement SIM card? The activation will take up to an hour.
      - Are you activating a SIM card with number transfer? The activation will take up to 24 hours. Your old SIM card will work right up until the Mobile Vikings SIM card is activated.
    Make sure you're logged in with the right e-mail address.
    Did you enter the right digits and still got an error message? Check your inbox and confirm your e-mail address. Then, try again. Still not okay? Call our helpdesk at 1976 or send us a message.
  • What do I have to do when I receive the SIM card?

    To activate a new SIM card or to activate a replacement SIM card, there’s one address:

  • My out-of-bundle usage in my account is incorrect. What does that mean?

    The usage we show on the website and Viking app, directly reflects what's been registered on the network. It takes up to a few minutes tops for recent calls, texts messages and data sessions to be processed in your usage. At this point, we also send out our notifications. 

    Occasionally, there is a longer delay in the processing of your usage. So be extra alert when your bundles are (almost) finished! Also, keep in mind that we can only process usage once it has been completed. 
    Convinced your usage isn't correct? Call our helpdesk for free using the number 1976 or send us a message, and we'll look into it!
  • How can I activate 4G on my smartphone or tablet?

    If you have a device that supports 4G and you are in a 4G zone, the only question remaining is how to activate 4G. The settings can vary slightly, but the following steps apply to most devices:

    • Apple (iPad, iPhone 5, 5s, 5c, 6, 6 Plus): Settings > Mobile data > select "Enable 4G".
    • Samsung (Android): Settings > More settings > Mobile networks > Network mode > select 4G, LTE or an automatic network selection.
    • HTC (Android): Settings > Mobile networks > Network mode > select 4G, LTE or an automatic network selection.
    • Sony (Android): Settings > Wireless and networks > Mobile networks > Network mode > select 4G, LTE or an automatic network selection.
    • Nokia (Windows Phone 8): Settings > Mobile networks > Highest connection speed > LTE.

    If, despite configuring the correct settings and being in the right location, you are unable to activate 4G, please contact our customer care team.
