Pros and cons

Pros

  • Entry plan Tarifa S at HUF 3,990 keeps the starting monthly cost low.
  • Unlimited data on Tarifa Z at HUF 6,990 for heavier users.
  • EU roaming is included, so travel costs do not change the monthly bill.
  • Data rollover protects unused allowance, and multi line discounts apply to a second line.
  • Billing covers contract, rolling and prepaid, so the style can change with the household.

Cons

  • A credit check is required, which rules out applicants who cannot pass one.
  • The most common contract length is 12, 24 and 1, so the longer terms tie people in.
  • Fees are adjusted once a year in line with CPI (Fees adjusted once a year in line with CPI), so the renewal price can sit above the entry price.
  • Support runs on phone and help centre, so live chat is not among the channels offered.

Who it suits

  • Households in Hungary that want the network itself rather than an MVNO.
  • People comfortable with 12, 24 and 1 contract terms.
  • Travellers in the EU who want roaming included rather than charged separately.

Who should look elsewhere

  • People who cannot pass a credit check.
  • Anyone wanting a plan without a contract term.

Plans and prices

Prices start at HUF 3,990 for the entry plan. Unlimited data sits at HUF 6,990 on Tarifa Z, so the gap between a capped allowance and unlimited data is worth weighing before signing up. Both figures are the introductory monthly prices, and fees are adjusted once a year in line with CPI, which means the amount paid later in the term can differ from the amount paid at the start. Readers comparing providers should treat the entry price as a starting point rather than a fixed monthly figure. Across the brands on our data, One Hungary sits at position 175 of 258 on price from, and at 66 of 173 on unlimited price.

Core features

One Hungary is a network seller rather than an MVNO, so the network supplies the service directly. Sim only is available, 5G is offered, and data rollover is included so unused allowance carries into the next billing period. A credit check is required before a plan is activated, which is the main gate for new customers. Multi line discounts are available, so a second line on the same account costs less than a standalone one. Taken together, the feature set is standard for a network provider rather than a premium one.

How it compares on our data

On the entry price, One Hungary ranks at position 175 out of 258 brands tracked for price from. That is a mid-table place, so cheaper entry tariffs do exist on our data. On the unlimited price, the ranking is stronger: position 66 out of 173 brands. In other words, the entry tariff is competitive but not standout, while the unlimited data option is among the more affordable ones listed.

The company behind it

The provider is One Magyarorszag Zrt., headquartered in Hungary and founded in 2025, so it is a recent network operation rather than a long-established incumbent. Support runs on phone and help centre. Customers who prefer phone contact or self-service reading rather than live chat fall within the stated support setup.

How One Hungary compares

Frequently asked questions

How much is the cheapest plan?+

The entry plan, Tarifa S, costs HUF 3,990 and comes with a capped data allowance on a 12, 24 and 1 contract. Unlimited data sits higher, at HUF 6,990 for Tarifa Z. Both are monthly prices, and fees are adjusted once a year in line with CPI.

What happens to the price after joining?+

The figures at sign-up are the starting monthly prices, not a fixed commitment. Fees are adjusted once a year in line with CPI, so the monthly amount can move during a 12, 24 and 1 contract. Budget for changes rather than assuming the same price for the full term.

Do I need a credit check to sign up?+

A credit check is required before a plan is activated. That makes it a poor fit for anyone who cannot pass one, and worth checking early if application is time sensitive. Other providers listed here may suit applicants who need a softer route.

Is there a contract term or can I go monthly?+

Contract lengths run to 12, 24 and 1, so most plans carry a term longer than a month. Rolling and prepaid billing are both available alongside contract, which suits people who cannot commit. Check which billing style each named tariff actually uses.

Does roaming cost extra in the EU?+

EU roaming is included on these plans, so trips inside the EU do not add a separate roaming charge to the bill. That is a straightforward arrangement for anyone crossing borders regularly. Data usage abroad still draws on the plan allowance.

Can I get more than one line on the account?+

Multi line discounts are available, so a second line on the same account is cheaper than taking it separately. This suits families sharing a bill under one name. Add lines only if the discount applies to the tariff you are on.

What is the unlimited data option?+

Unlimited data sits at HUF 6,990 monthly, and on our data that price ranks at position 66 of 173. Heavy users who would otherwise pay overage get predictable monthly outgoings instead.

What support can I reach?+

Support runs on phone and help centre, which means phone and a help centre. Live chat is not among the listed channels, so callers who prefer typing in real time may find that limiting. Phone support suits urgent network questions.
