eSIM and SIM cards in Luxembourg

If you have an EU plan, stop reading

• Roam-like-at-home applies. A SIM from any EU or EEA country works here at your domestic rates, with your domestic allowance. Buying anything local is money wasted.
• UK plans are not covered any more. Several UK networks reintroduced EU roaming charges after Brexit - check yours before you land rather than after.

The border-hopping quirk

• Luxembourg is 82 km long. Near the borders your phone will happily connect to a French, Belgian or German mast.
• Within the EU this costs you nothing thanks to roam-like-at-home - but if you are on a non-EU plan with a Luxembourg-only package, it matters.

Local prepaid SIM

• POST and Tango cover the country and coverage is complete.
• Prepaid packs are sold at the airport, the station and in shops.
• Bring your passport.

eSIM

• An eSIM is live before you land and skips the shop entirely, which on a short trip is the whole argument for it.
• Check your phone takes one. Most flagship phones since 2019 do; most budget models do not.

Practical points

• Keep your home number reachable for two-factor codes. If you swap in a local SIM as your only card, bank apps that text a code to your home number stop working at the worst possible moment. A dual-SIM phone, or an eSIM alongside your home SIM, solves it.
• Wi-fi is widespread in cafes, hotels and stations.
