Can I switch from a subscription to a prepaid SIM card?

Yes! You can do this via product settings through your My Viking account on the website, or in the app.

Will you switch immediately? In that case, your subscription bundles will remain valid until their expiry date. You'll use those first, and only when they're used up or expired you'll start using the bundles of your top-up. You can also choose to switch as soon as your current subscription bundles expire.
