Scored 8.9 / 10 by NomadCue.

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.
