Our verdict
NOS sells roaming as a carrier add-on rather than a standalone travel eSIM, which suits existing NOS customers who want data on one bill. Day passes start at €7.50 for 200MB, and bundle prices differ by country, at €14.99 in the UK against €30 in the US.

Pros and cons
Pros
- Hotspot sharing is supported, so a phone on the roaming line can serve a laptop or tablet
- A day pass of 200MB costs €7.50, a low entry price for a quick trip
- Bundles are built around short trip and long trip travellers, so short breaks and longer trips both have an option
- Support runs on phone, help centre and community, with a help centre and a phone line behind the add-on
Cons
- Unlimited data is not offered, so a heavy streaming day runs out inside the bundle you bought
- Bundle prices differ sharply by country: €14.99 in the UK against €30 in the US and €30 in Japan
- Roaming is sold as a carrier plan on an existing NOS line, so buying needs that line first
Who it suits
- NOS subscribers who want roaming added to the bill they already pay
- Travellers on a short trip who need maps and messaging rather than a large bundle
- Holidaymakers heading to the UK, US, Japan, Thailand, Turkey or Mexico
Who should look elsewhere
- Travellers who need unlimited data for long streaming sessions
- Anyone buying a one-off travel eSIM, where eSIMGo.is from $0.99 works as a standalone purchase
- Travellers wanting one flat country list, where Zwitchy covers 200 countries
Who runs it
NOS roaming is run by NOS Comunicações, S.A., a carrier based in Portugal. Buying a roaming pass means adding a carrier plan to an existing NOS line, so the data lands on a bill you already pay rather than a separate travel purchase. Support runs on phone, help centre and community, so there is a phone line and a help centre if a pass misbehaves abroad.

Frequently asked questions
How much does a NOS roaming day pass cost?+
A day pass costs €7.50 and carries 200MB, which suits maps, messaging and light browsing on a long travel day. Bundles are priced separately and the entry rate works out at €1.50 per GB. Top-ups are available if the day pass runs out mid trip.
Which countries does NOS roaming cover?+
NOS roaming reaches from 100 countries and the region is listed as global. The offer mixes day passes with data bundles, so a short hop and a longer holiday can both be covered. Destinations such as the UK, US, Japan, Thailand, Turkey and Mexico each carry their own bundle price.
Do I need a NOS plan to buy roaming data?+
Roaming here is sold as a carrier product, so it is added to an existing NOS line rather than bought as a separate travel eSIM. Existing customers can top up and manage the add-on from their normal account. Travellers without a NOS line may find a standalone eSIM easier to purchase.
How long is a NOS data bundle valid?+
Bundle validity runs for a set number of days after activation, and a fair use policy caps how often the day pass renews in a month. Larger bundles must be used within a set window from purchase, so unused data is lost rather than carried over. Check the fair use policy before committing to a big bundle.
Why do roaming prices differ by country?+
Prices follow the network serving each country. A bundle in the UK costs €14.99, while the same size costs €30 in the US and €30 in Japan. Far destinations cost more to serve, so a multi-country trip is worth pricing bundle by bundle before you buy.
Can I share NOS roaming data with other devices?+
Hotspot sharing is supported, and NOS sells hotspot hardware of its own for the same job. A roaming line can therefore serve a laptop or tablet on the move. Keep an eye on the fair use policy, because day pass renewals are capped within a month.
Does NOS roaming include unlimited data?+
Unlimited data is not part of the NOS roaming offer, so every plan is a day pass or a sized bundle. In eligible countries usage is not subject to the EU monthly roaming data cap, which adds some headroom. Heavy streaming still counts against the bundle you bought.
Who is NOS roaming aimed at?+
The plans target short trip and long trip travellers, so both short breaks and longer trips have a matching option. NOS is a carrier, which means the data is added to an existing home line. Support is on phone, help centre and community if a pass needs help while abroad.
