## Activation in a few minutes

Do the install before departure, while on WiFi. Open your phone settings, choose to add an eSIM and scan the QR code you received by email. Label the profile “Hungary” so it is easy to spot. When you land, set the eSIM as your data line and switch on data roaming for it — that is normal for travel eSIMs and adds no fees, because the plan is prepaid. Within seconds you are online, with no need to hunt for public WiFi.

## Tips to save data

A few small habits make your gigabytes last in Hungary. 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.

## 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 Hungary, that means a simple experience: buy it, scan it, and you are ready before you board the plane.

## 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 Hungary, 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.

## 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 Hungary will be trouble-free.
