eSIM for Hungary — Budapest and the thermal baths

Traveling to Hungary is an incredible experience, but arriving without data can ruin the first moments: no Google Maps to get out of the airport, no way to look up the hotel, no way to contact whoever is waiting for you. The solution is simple and has been the standard among experienced travelers for years: an eSIM for Hungary.

In this guide, we tell you everything you need to know before traveling to Hungary: what coverage you can expect in Budapest and Lake Balaton, how many GB you really need, how to activate the eSIM, and the best connectivity tips from those who have already traveled there.

Spoiler: with PuraSim, you have local data from the moment your plane lands, no contracts, no physical SIM, and no bill surprises.

Why do you need an eSIM to travel to Hungary?

International roaming from European and Latin American operators can cost you between 10 and 30 euros or dollars per day in Hungary. A local eSIM gives you data at local prices, with no absurd daily limits and with 4G or 5G speeds where the network allows.

The difference between going with roaming and with a PuraSim eSIM is huge:

• Traditional roaming: fixed daily rate even if you barely use data, speed often limited to 3G, surprise bills upon return.
• PuraSim eSIM for Hungary: you only pay for what you contract, full local data at maximum available speed, activation in 5 minutes from anywhere.

In addition, with an eSIM, you can keep your original phone number active to receive calls and SMS, as the eSIM operates in a separate virtual slot. You don't have to choose between local connectivity and your usual number.

For Hungary, where Budapest's thermal baths allow you to keep your mobile in lockers; the BKK app covers all transport, having stable data is especially important. Coverage in Budapest and Lake Balaton is generally good, but there are areas where without a well-configured local eSIM, you would be in the dark.

Data coverage in Hungary: what you can expect

Coverage in Hungary varies quite a bit depending on the area. In the main urban and tourist areas (Budapest and Lake Balaton), you will find 4G and in some cases 5G networks. The experience is comparable to what you would have at home.

However, as in any destination, there are areas where the signal is more limited:

• Main cities: stable 4G/5G, perfect for streaming, browsing, and video calls.
• Rural and nature areas: coverage can drop to 3G or even lose signal in remote areas.
• Transport: trains, ferries, and intercity buses have variable coverage; in cities generally good.

Key tip: Budapest's thermal baths allow you to keep your mobile in lockers; the BKK app covers all transport

To maximize coverage in Hungary, PuraSim uses the local networks with the best available infrastructure through local roaming agreements. This means that your eSIM automatically connects to the network with the best signal at all times.

How many GB do you need to travel to Hungary?

This is the million-dollar question. The short answer: 5-7 GB for 1 week. The long answer depends on how you use your mobile during the trip.

Here is a guide to actual consumption by type of daily use:

• Basic use (maps, messages, occasional queries): 300-500 MB/day
• Moderate use (social media, photos, continuous browsing): 800 MB-1.5 GB/day
• Intensive use (remote work, streaming, video calls): 2-4 GB/day

For a trip to Hungary lasting 1 week, our recommendation is to contract 5-7 GB for 1 week. This is enough for most travelers with normal use: Google Maps constantly running, Instagram, WhatsApp, and an occasional search.

If you are going to work remotely or plan to make frequent video calls, upgrade to the next higher plan. PuraSim plans allow you to top up data if you run out, so it's not a problem if you fall short: you won't suddenly lose coverage.

How to activate your eSIM for Hungary step by step

Activating a PuraSim eSIM is as simple as scanning a QR code. There's no need to go to a store, no need to wait for any shipment. The entire process takes less than 5 minutes:

1. Purchase your plan at purasim.com for Hungary. You will receive an email with the QR code.
2. Install the eSIM: go to Settings → Mobile Data → Add Data Plan (on iPhone) or Settings → Connections → SIM Manager (on Android).
3. Scan the QR code or manually enter the activation data.
4. Set up mobile data: make sure to select the PuraSim eSIM as the default data line.
5. Activate data roaming in the PuraSim eSIM settings (necessary for it to work on local networks).

You can install the eSIM before leaving home and configure it to activate automatically when you arrive in Hungary, or activate it manually when you land.

Important: verify that your phone is eSIM compatible before purchasing. Most iPhones from XS, Samsung Galaxy from S20, and Google Pixel from 3 are compatible. Check the complete list at purasim.com.

Local connectivity tips for Hungary

Beyond getting the right eSIM, there are a few tricks that make a difference in staying connected throughout your trip to Hungary:

• Download offline maps before you leave. Google Maps and Maps.me allow you to download maps of all of Hungary or specific cities. This way you can navigate without using data when you are in areas with a weak signal.
• Use airplane mode strategically. On long flights, trains, or ferries, activating airplane mode preserves battery and data. Connect to available WiFi if there is any.
• WhatsApp and Telegram over data. Calls through these apps consume much less than an international call. Configure them for high-quality calls only when you are on WiFi.
• Share connection carefully. Hotspot consumes data quickly, especially if there are other devices connected (laptop, tablet). Use it only when necessary.

And the most important tip: Budapest's thermal baths allow you to carry your mobile in lockers; the BKK app covers all transport

With these tricks and a good PuraSim data plan, your trip to Hungary will have the connectivity you need without unnecessary expenses.
