Prices, terms and what to check when renting a car at Budapest Ferenc Liszt Airport or Hungary's other airports.

## Get online at the airport

Install a MerrSIM eSIM for Hungary (from €1.99, 10 GB €10.49) before departure and you’re online the moment you land at Budapest Ferenc Liszt Airport — no WiFi hunt, no roaming.

## Coverage and 5G speed in Hungary

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 Hungary 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 Hungary.

## 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.

## 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.

## 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.

## FAQ

### How do I get online as soon as I arrive in Hungary?
