# Mobile network coverage in Luxembourg

> Mobile coverage in Luxembourg: POST, Orange dhe Tango. MerrSIM connects on a local 4G/5G network.

Luxembourg has several main operators: POST, Orange dhe Tango. All offer good 4G/5G coverage in cities and tourist areas.

## Which network MerrSIM uses

The MerrSIM Luxembourg eSIM connects to the main local networks (POST, Orange dhe Tango) at 4G/LTE and 5G where available, for steady coverage including around the Chemin de la Corniche. Public transport is free nationwide; an eSIM gives you live schedules.

## Tip for rural areas

In remote villages or mountains coverage may weaken, as with any operator. Download offline maps to be safe.

## How an eSIM works

An eSIM is a digital SIM built into your phone: there is no physical card to insert. You buy it online, get a QR code by email and scan it in your settings. Once installed, the profile lives on your phone and activates when you reach Luxembourg, connecting automatically to a local partner network. You can keep your main SIM at the same time, so your number still gets calls and texts while the eSIM handles data.

## Coverage and 5G speed in Luxembourg

The eSIM connects to the main local operators, so you get the same coverage as a local, including 4G/LTE and 5G where available. In the cities and tourist areas of Luxembourg the signal is strong and stable; in very remote villages or mountains it can weaken, as with any operator. Hotspot is included, so you can share the connection with your laptop or a travel companion at no extra cost.

## How much data you really need

For normal use — maps, messaging, social media and the odd video — budget about 300–700 MB a day. A light traveller is fine with 3–5 GB for a week, while anyone doing video calls, streaming or laptop hotspot will want 10–20 GB. In Luxembourg, download offline maps and use hotel WiFi for big downloads; that way a 10 GB plan comfortably lasts two weeks. If you run out, you buy a new plan in the app with no waiting.

## Does your phone support eSIM?

Before you buy, check two things. First, the phone must be eSIM-compatible: iPhone XR/XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many recent Motorola, Huawei and Oppo models. Second, it must be carrier-unlocked. You can verify by dialling *#06# — if an EID number appears, your phone supports eSIM. This saves you any surprises when you arrive in Luxembourg.

## Common mistakes to avoid

Three mistakes often spoil the start of a trip. First: buying the eSIM at the last minute at the airport, when you have no WiFi to install it — do it at home. Second: forgetting to switch on data roaming for the eSIM line, which makes it look like it is not working. Third: leaving mobile data on your home SIM, which racks up roaming charges. Check these three and your connection in Luxembourg will be trouble-free.
