How do I activate the replacement SIM card for the new platform?

– Updated

As of August 2018, we’ll be sending certain Vikings a replacement SIM card (not everyone needs one). As to exactly why, you can read more about that here. So, if you’ve received one without requesting it yourself, you need to activate it asap. It only takes three steps:

  1. With your old SIM card, text SWAP XXXX to 1984. These XXXX are the last 4 digits of your replacement SIM card’s number. You’ll find it on the back of your replacement SIM card: it’s 19 digits long, but you only need the last 4.
  2. If your digits are correct, we’ll send you an SMS to confirm. From that moment on, always keep your replacement SIM card with you. As soon as the network of your “old” SIM card drops (this will take 30 minutes max), switch off your device and insert the new SIM card. The default PIN code for your new SIM card is 1111, and you can easily change it through your device settings.
  3. Now it’s only a matter of setting up your mobile internet correctly. To do so, head over to
