OneCall review

The roaming add-on starts at NOK 149 for the reference countries, as a fixed data bundle rather than a daily rate. The median entry price across the brands on the site is €5, so OneCall sits above the middle of the market.

Each reference plan bundles a set amount of data for a short validity window, aimed at short trip travellers, with bundles priced from NOK 149. The add-on stops at the allowance and expires at the end of that window, so a heavier trip would need a top-up.

Unlimited data is not offered. The Full Data plan carries a fair use policy, and once heavy use builds up in a month you need to buy FartsPafyll to restore normal speed, while 57.2% of the listed brands do sell unlimited data.

Coverage runs to 35 countries, with reference plans listed for the US, Japan, Thailand and Turkey, and EU and EEA roaming included at no extra cost. The median across the site is 74, so OneCall is a smaller map than most.

Destinations outside the reference countries are charged per MB as you roam, so the bill is harder to predict ahead of the trip. EU and EEA travel is the exception, with roaming included at no extra cost, and the network behind the service is Telia.

OneCall runs on the Telia network and 5G is supported, so a handset that handles domestic 5G will handle it abroad too. Roaming sits with the same operator, Telia Norge AS, based in no, rather than a separate travel-only seller.

OneCall is sold by a mobile virtual network operator based in no, so the plan runs on its own network rather than a marketplace listing. It is aimed at short trip travellers, and top-ups are available for trips that use more than the bundle.

Help is offered on phone, chat and email, so phone, chat, email and a help centre are all listed. Questions about a bundle that has run out mid trip can go to the same operator team rather than to the home network provider.
