Frequently asked questions
What does a One Hungary day pass cost?+
Day-pass prices are banded, with the US, Mexico and Africa destinations such as South Africa and Egypt in the lower band, and Japan and Thailand in the higher band. Non-EU Europe is priced at the higher level too, and the global pass spans both bands. Home plans start at HUF 3,990.
Which countries does the day pass skip?+
The UK and Turkey are not in the day-pass zones: the UK is handled as an EU roaming destination and Turkey as a separate roaming zone. Both fall outside the 73 countries the day pass reaches, so travellers heading there rely on the plan's own roaming terms.
Is data really unlimited abroad?+
Unlimited data is included on the plan, but roaming draws on the plan's own data allowance, which differs by tariff, and plans start at HUF 3,990. The unlimited option is capped in EU roaming, and roaming speed is throttled once the allowance is used up.
Who is One Hungary aimed at?+
It is a Hungarian carrier aimed at short trip rather than long stays, run by One Magyarorszag Zrt. and based in Hungary. It suits residents in Hungary who want a home plan with a roaming add-on, not visitors buying a prepaid eSIM at the airport.
Does One Hungary run on 5G?+
Yes. unlimited data, 5g and carrier plan lists unlimited data, 5G and a carrier plan, so the service runs on the operator's own network rather than a resale of another brand's eSIM. Top-ups are available if a trip runs long.
Can I top up and get help while travelling?+
Top-ups are available, so extra credit can be added without visiting a store. Support runs on phone, email and help centre, so a phone call, an email or the help centre can sort out a day pass mid-trip.
Is One Hungary a marketplace or a carrier?+
It is a carrier, One Magyarorszag Zrt., founded in 2025 and headquartered in Hungary. That means you hold a home plan and add roaming to it, rather than buying a single-trip eSIM that expires after a set window.
