# How to activate an eSIM in Croatia (step by step)

> How to activate a Croatia eSIM: install the QR before departure, turn on Data Roaming, connect automatically.

Activating a Croatia eSIM takes a few minutes. Do it before departure so you connect on arrival.

## Before you leave

- Make sure your phone is eSIM-compatible and unlocked.
- Buy the Croatia plan at MerrSIM and get the QR code by email.
- Connect to WiFi and scan it: Settings → Mobile → Add eSIM.
- Label the eSIM “Croatia”.

## When you arrive in Croatia

- Set the eSIM as your data line and turn on Data Roaming for it.
- Keep your main number for calls/SMS.
- You connect automatically to the local network (Hrvatski Telekom, A1 dhe Telemach).

Ferry schedules change often; with an eSIM you check them instantly on Jadrolinija or Google Maps.

## 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 Croatia, 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 Croatia

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 Croatia 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.

## 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 Croatia.

## eSIM versus roaming

Roaming with your home carrier can be expensive outside bundles — sometimes several euros per gigabyte, with bills that land after the trip. A local eSIM turns that into a fixed price you know up front: you pay in advance, you know exactly how many GB you have, and there are no hidden fees. For a trip to Croatia, that means peace of mind and often a real saving compared with leaving roaming switched on unchecked.

## 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 Croatia, 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.
