- 2Then log in to your My Viking account to check if you still have enough calling credit or data bundles. Got an unpaid invoice? That could be the issue too. 
- 3Next, check if you’re connected to a network. No connection? Try connecting manually via your phone’s settings. Select your device in our setup guide, go to ‘Network’ > ‘Select a network’, and follow the steps. 
- 4Still not working? Try your (physical) SIM card in another device, just to be sure the problem isn’t your phone. 
- 5Are you abroad? Try another provider. And yep, you’ll need to restart your device again. Also, make sure you’re using the correct number format - like +32 for Belgium or +33 for France.
