How long will my calling credit and bundle including the free advantages be valid?

1 calendar month, starting from your most recent top-up. For example, if you top up on 8 November at 12.35 am, your bundle will remain valid until 08 December 12.35 am. What's included in your bundle? With a top-up you will receive a SMS bundle, data bundle and a Viking advantage bundle (free calls to other Vikings). In addition, you will receive call credit for the value that you have recharded your prepaid. You can use the call credit to make calls.

Context
We define one calendar month as the period starting on a specific day of a month until the same day the next month. A calendar month can, therefore, be 28, 29 (in leap years), 30 or 31 days long. Another example: if you top up in March, your bundle will be valid for 31 days. If you top up in April, your bundle will be valid for 30 days.

And my remaining calling credit?
If you have any calling credit left, it will be transferred to the next month and added to your next top-up. Calling credit from a top-up is valid for 6 months and then expires.

What happens after a month?
If the month is over and you haven't topped up yet, you'll be calling, texting, and surfing out-of-bundle and the out-of-bundle rates will apply.
