Choosing the right network is important when travelling abroad. You can manually connect your phone to another network, or turn it on and off when crossing borders. Your phone will then automatically search for a network in the country you are in.

It is also best to switch off 4G abroad. 3G works better outside Belgium.

If you cannot connect to the local mobile Internet immediately, go over this checklist before you do anything else.

First of all: Check whether the settings of mobile Internet are still correct. You can double check on this page (This should solve 90% of all the cases). If it still doesn't work, please try these steps:

• Restart your device several times as soon as you arrive abroad.
• Try to establish the connection with the different local networks manually through your device settings. One network may provide a more stable connection than another.
• Check whether the option 'data roaming' is enabled in your device settings. This will usually be available in the 'Mobile networks' menu.

Of course you can. Right here. The only thing to keep in mind is to make sure you have no outstanding balance in your subscription. As soon as your balance has been settled, you can switch.

Per month there's a limit to the amount of times you can switch between a subscription and a prepaid SIM card.

Here's some examples:

• Subscription -> prepaid SIM card -> subscription. After this you can no longer switch to a prepaid SIM card in that same month.
• Prepaid SIM card -> subscription -> prepaid SIM card -> subscription. After this you can no longer switch to a prepaid SIM card in that same month.

Also check: "Can I change the price plan for a subscription?"

There are multiple ways to log in. You can use your phone number or your email address. If one doesn't work, try the other. If they both don't work, try changing your password.

We know some Vikings are experiencing issues these past days, and we’re trying very hard to solve all the issues as quickly as possible. In the meantime, check here for answers to the most urgent questions.


1. Having problems with mobile internet, calling, or texting (abroad)?
Check whether you have enough calling credit. Due to a technical issue, we were temporarily not sending any notifications for this. But we are now. You can also check your usage in the Viking App.

Are you abroad, and are you without mobile internet? Check whether your mobile internet is configured correctly.

2. You didn’t receive any notification about the expiry of your bundle or calling credit?
This was a known issue, but it has been solved now. However:

Beware: it's possible you receive a notification (by SMS or email) about an expired bundle, even if you still have active bundles. This notification is referring to an older bundle, which has just expired. 

Best to keep a very stern eye on your usage and your bundles.

3. What does “PDP-authentication error” mean?
If you see this, check your calling credit. Because we’re temporarily not sending out any notifications about your calling credit due to a technical issue. You can also see your usage in the Viking App.


4. You don’t have mobile internet abroad?
Check whether your mobile internet has been configured correctly.


5. I can’t log in to my account. What should I do?
Your username is case-sensitive now, so your browser’s autofill might not work. If that’s the case, log in using your phone number. Works every time.


6. Easy Payments in the Viking App aren’t working. What can I do?
Due to technical issues, Easy Payments are currently unavailable in the Viking App. Our app team is hard at work to make them available again.

In the meantime, try topping up via text message. Read all about it here. A top-up via SMS is just as easy and mobile as using the Viking App.

You'll find an overview of further (permanent) changes after 24/6 here.
