Our verdict
Base is a Belgian carrier, Telenet Group NV (trading under the commercial name BASE), so the roaming add-on suits subscribers who already pay for a home plan and travel inside Europe. Coverage of 27 countries keeps the offer regional, and a traveler planning a single trip will find little reason to move to it.

Pros and cons
Pros
- Roaming sits on a home network plan, listed as a carrier plan in 5g and carrier plan, so no separate travel SIM is needed for the trip.
- A single price covers the US, Japan, Thailand, Turkey and other listed non-EU countries, while EU roaming is already included in the plan.
- 5G is available on the network, and top-ups let credit be added while traveling.
Cons
- Unlimited data is not offered: bundles are metered, and standard rates apply once the allowance is used up.
- Coverage of 27 countries sits well below the site median 74.
- Support runs on help centre only, so a question raised abroad gets a written answer.
Who it suits
- Subscribers on a Belgian Base plan who want to keep the same number across Europe.
- Travelers heading to the US, Japan, Thailand or Turkey who prefer a carrier bundle to a travel seller.
- People who want 5G from their own network abroad rather than a marketplace product.
Who should look elsewhere
- A traveler who wants a disposable travel eSIM for a short trip: eSIMGo.is starts at $0.99.
- Anyone crossing many countries on a single plan: Zwitchy covers 200 countries against 27 here.
- Heavy-data travelers who want unlimited data, which Base roaming bundles do not include.
Coverage and networks
Roaming listed for Base reaches 27 countries, which suits a trip around Europe rather than a multi-continent itinerary. Network quality is the stronger side of the offer, with 5G available to customers on the plan. Buyers who need a wider map of destinations, or a plan that crosses continents, will find this list short.
What data costs
The entry point is €15, and the price per GB of €7.50 sits above the site median €1.50. Reference bundles step up from Roaming Lite to Roaming Smart and Roaming Max, each at a single price, and the same price applies to the US, Japan, Thailand, Turkey and other listed non-EU countries. EU roaming is included in the plan.

Frequently asked questions
How much does roaming with Base cost?+
Roaming bundles start at €15, with a price per GB of €7.50. The reference options run from Roaming Lite through Roaming Smart to Roaming Max, and each carries a single price for the US, Japan, Thailand, Turkey and other listed non-EU countries.
How much data is in the bundle and how long does it last?+
Each roaming bundle carries a set monthly allowance rather than unlimited data, since unlimited data is not offered on these plans. The reference options step up from Roaming Lite to Roaming Max, starting at €15, and the bundle renews each month. Standard roaming rates apply once the allowance is used up.
Which countries can I roam in?+
Base lists 27 countries for roaming, which covers the main European markets plus listed destinations outside Europe. Roaming inside the EU is already included in the plan, so the extra cost applies to trips that leave the EU. Travelers crossing several continents will find that list short.
Is Base a travel eSIM or a home network?+
Base is a carrier, Telenet Group NV (trading under the commercial name BASE), selling a Belgian home network plan with roaming added on top. That suits people who already hold a Base subscription and travel inside Europe, rather than holidaymakers who want a throwaway travel SIM bought for the trip alone.
Does Base offer unlimited data?+
Unlimited data is not offered on Base roaming plans, so data runs through a monthly bundle that starts at €15. The fair use policy sets out that out of bundle usage falls back to standard rates, and EU usage stays inside the plan until the bundle or plan allowance is exceeded.
Will the connection be fast abroad?+
The network offers 5G to customers, and both 5G and the carrier plan appear in the feature list: 5g and carrier plan. Travelers on a recent handset keep the speed of their own network rather than a travel partner's. Top-ups are offered, so credit can be added while away.
How do I get help if something goes wrong?+
Support runs through help centre only, so questions are handled in writing rather than by phone. As a carrier, Base serves customers on its own network, and the same route applies whether the problem starts in Belgium or abroad. Travelers who want live help mid-trip should expect a slower answer.
