Pros and cons
Pros
- Unlimited data is part of the plan, and 5G is included
- Reaches 82 countries on the POST network
- Sold as a carrier plan by POST Telecom S.A., based in Luxembourg since 1992
- Support runs on email, phone and help centre
Cons
- Entry price of €15 sits above the site median of €5
- Coverage of 82 countries ranks at 142 of the 303 brands compared, so wider maps exist
- Unlimited data runs under an EU fair use policy, so a new option of the same category comes only once most of the previous one is used
Who it suits
- Travellers already in Luxembourg who want to keep the same carrier abroad
- Anyone who needs data without watching a data allowance
- Travellers on long trips who would rather not track a data allowance
Who should look elsewhere
- Travellers on a tight budget, who will find €15 above the site median of €5
- Anyone after the widest map, since Zwitchy covers 200 countries against 82 here
- Travellers wanting a self-service eSIM, since this is sold as a carrier plan by a home operator

Frequently asked questions
How much does a POST Luxembourg around the world plan cost?+
Plans start at €15. That is above the site median of €5, so it reads as a mid-range carrier price rather than a budget one. Add-on data options go further, with the site maximum at €87.70.
Is the data really unlimited?+
Unlimited data is listed as yes. It is a carrier plan from POST Telecom S.A., a Luxembourg operator founded in 1992, running on the POST network. The unlimited claim arrives with an EU fair use policy attached.
What does the fair use policy mean in practice?+
EU fair use is set at a minimum equal to the volume included in the offer, so heavy use can be restricted. A new option of the same category becomes available only once most of the previous one has been used, which stretches the top-up rhythm.
How many countries can I use it in?+
Coverage runs to 82 countries on the POST network, above the site median of 74. It still ranks at 142 of the brands compared, so a wider map exists for trips across several continents.
What network will I be on while travelling?+
The networks listed are POST, meaning one home carrier rather than a set of partner networks. Good if you want a single provider, less flexible if a partner would give you a local network in a country you visit often.
How do I get help if something goes wrong abroad?+
Support runs on email, phone and help centre, so email, phone and a help centre are all there to reach. Because this is a carrier plan from a Luxembourg operator, help is arranged through the home operator rather than a travel-focused support desk.
Is it an eSIM or a physical plan from a carrier?+
It is listed as a carrier plan, not a marketplace product. The seller type is carrier, the most common model on the site at 59.9%, so setup runs through an existing mobile relationship.
Is POST Luxembourg the cheapest way to stay connected?+
Not on price. The entry point of €15 ranks at 260 of the brands compared, and coverage of 82 countries ranks at 142. Cheaper entry points exist if your trip is short.
