How can I top-up my account using Viking App?
To use the Viking App to top-up your SIM cards you need to configure the SMS Top-up method. Add your credit card using Viking account on our website in "SMS top-up" section of your account.
Even when the SMS Top-up method is not active, you can still top-up the account using Viking Points.
On the Android and iOS devices, use "Top-up" button in the top-right corner.
For Windows Phone click on three dots visible in the top-right corner. Pick "Top-up" from the list.
After that pick the right top-up and confirm the transaction. All you need to do now is wait a while for the confirmation SMS and that's it! :)
