If you’re landing at Adolfo Suárez Madrid–Barajas Airport (MAD) for the first time, here is what to know so you don’t get lost.

## Get online at the airport

## 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 Spain, 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.

## 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 Spain, 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 Spain.

## Why travellers choose MerrSIM

MerrSIM builds local plans for dozens of destinations, at a fixed price in euros — no dollar exchange rate and no surprises. Every plan includes hotspot, instant QR activation and no document registration. The app and support are in Albanian, which makes it easy for the diaspora and travellers from the region. For Spain, that means a simple experience: buy it, scan it, and you are ready before you board the plane.

## No registration, no shop queue

Many EU countries require identity verification for local SIM cards, which means a queue, a shop and sometimes even a local address. A travel eSIM skips all of that: it is sold as an international data service, with no passport and no contract. You have it ready before you set off for Spain, so you land and are online immediately — no time wasted at the airport and no risk of surprise roaming bills.
