# How much data do you need for Greece?

> How much data for Greece: 5 GB a week, 10 GB two weeks. MerrSIM plans from €1.49.

Before buying a Greece eSIM, work out how many GB you need. It depends on your days and what you do online. In Oia on Santorini, the sunset is perhaps the most-posted photo on Instagram — don’t miss it with an active eSIM.

## How much data you need

- Light use (maps, WhatsApp): ~300 MB/day
- Moderate use (social, photos): ~700 MB/day
- Heavy use (video, hotspot): 1–2 GB/day

Multiply by your days and add a little buffer.

## The right MerrSIM plan

Inter-island ferries have weak WiFi; an eSIM keeps you online for bookings and maps.

## 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 Greece.

## 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 Greece, 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.

## Tips to save data

A few small habits make your gigabytes last in Greece. Download Google Maps offline before you head out, set video quality to “Auto” or 480p, and turn off background app refresh. Use hotel WiFi for big updates and high-resolution photo uploads. With these steps, even a modest plan covers the whole trip, and your hotspot stays free for the moments you really need it.

## 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 Greece, so you land and are online immediately — no time wasted at the airport and no risk of surprise roaming bills.

## 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 Greece, 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.
