Hungary eSIM

List the moments that may need live information: airport fare and validation, final interchange, intercity barcode, local departure, accommodation message and return. Compare data, validity period, written territory, supported devices and checkout total against those moments, then check how support works. Mobile tickets can make data valuable, but select and retain a currently permitted fallback rather than assuming the app, battery and network will all be available.

Choose by destination, interchange and current fare product. Official guidance treats 100E as the direct city-centre Airport Express with a dedicated ticket that must be validated; 200E uses eligible regular BKK products and normally connects at Kőbánya-Kispest, with night routing that can differ. The 100E ticket is not the onward city ticket, and it is not the 200E product. Follow the displayed paper, mobile or contactless validation steps and save the final connection separately.

Keep the Budapest departure station, ticket barcode, Debrecen arrival station and exit as separate records. Retrieve the current local tram or bus departure before leaving the terminal, then match the correct stop to the full accommodation address rather than only its name. Store an allowed local ticket method, lodging contact and last intercity return offline. That sequence remains usable if a platform, local service or mobile-ticket screen changes.

Start with the exact city and station on the intercity booking; Szeged and Pécs are not interchangeable. At arrival, use current official or operator service information for the local tram or bus, confirm the stop and final street entrance, and preserve a permitted ticket fallback outside the app. Save the last route back to the same booked station before leaving it. Do not infer today's local pattern from a remembered timetable or from the other city.

Choose the actual shore town, station and accommodation—Siófok, Balatonfüred and Keszthely are different stops, not one Lake Balaton destination. Add any local bus, walk, ferry dock or pickup as another stage. Before moving along the shore, download the exact return platform or dock, last departure, ticket and meeting point. Seasonal frequency, shoreline distance and terrain do not prove lake-wide reception, so the return must remain usable offline.

Use only the countries written in the plan. A Hungary-only listing provides no basis for service in Austria, Slovakia, Ukraine, Romania, Serbia, Croatia or Slovenia, even if an intercity or cross-border ticket continues there. Check every neighboring country separately and choose a regional product only when each required territory appears. Keep the onward ticket, border information, final address and an offline route available; the eSIM does not establish border or transport availability.

Yes. WhatsApp stays linked to your usual number and runs on the eSIM's data. On a dual-SIM phone, your usual SIM can stay on for ordinary calls and texts. Your home carrier may charge for calls, texts or data on that line, so turn off data roaming there.

No. Horizon plans are data-only, with no phone number for calls or texts. Use apps such as WhatsApp or FaceTime over the eSIM's data, or keep your usual SIM on for ordinary calls and texts.

Yes. A travel eSIM connects to local networks as a roaming line, so turn on data roaming for the Horizon eSIM when you arrive. The plan is prepaid, so Horizon does not bill you after checkout. Keep data roaming off on your usual SIM to avoid charges from your home carrier.

You can buy more. If your plan supports a top-up, My eSIMs shows the data you can add to the same eSIM. If it does not, buy another Hungary plan and install it the same way.

It will if your phone supports eSIM and is not locked to your home carrier. Many recent iPhone and Android models do, but some regional versions do not, so check your exact model on the supported devices page before you buy.

No. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.

Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
