What's the validity period of the bundles after a top-up?
The packages in the Viking Net tariff are always valid for a period of 31 days from the top-up. If there is more than one top-up made during the same day, the bundles shall be multiplied, but its validity period shall be equal to 31 days. So it's best to top-up your account on the 31st day, of the validity period, of your previous top-up in order to retain its continuity. By retaining the continuity of the top-ups, the remaining unused data package shall accumulate with the package from the new top-up.
