One Hungary is one local-network option for visitors, but the best prepaid choice depends on the current package and the route beyond Budapest.
Tourists should verify registration, validity and EU roaming rather than relying on an old Vodafone-branded offer.
NoveSIM provides data-only travel eSIMs without a Hungarian number, standard calls or SMS.
Quick answer: Consider One when its current prepaid package fits your allowance and route, especially if you need a Hungarian number. Compare Telekom and Yettel coverage as well; use a travel eSIM for simpler data-only setup.

Coverage for the Full Route
Check Budapest, Lake Balaton, motorways and rural stops separately. Review Hungary network coverage rather than selecting only by shop price.
Alternative: Travel eSIM
A Hungary eSIM can be prepared before arrival on a compatible unlocked phone, but it does not provide a local number.

FAQ
Does One offer tourist service?
Check its current prepaid products and registration requirements at an authorised outlet.
Is EU roaming identical to domestic data?
Not always; inspect the allowance.
Do I get a Hungarian number?
A local SIM normally does; NoveSIM data-only plans do not.
Is One always the best network?
No. Coverage depends on the exact route.
Final Recommendation
Choose One only after confirming the live prepaid terms and route coverage. Compare rival networks and use eSIM when quick data matters more than a local number.
