Best eSIM for Hungary 2026: Budapest Plans and Network Names

For most Hungary trips, I would start with Nomad’s 20GB for €17.79 or Ubigi’s 10GB for €9 if seven days is enough. Jetpac is worth checking when you want 30GB or 40GB. Holafly offers unlimited phone data with a separate hotspot allowance, while Airalo is an option for travellers who already like its app and top-up flow.

The less obvious part of choosing a Hungary eSIM is matching the network names. A page may say Vodafone even though the Hungarian brand is now One, or Telenor even though it became Yettel in 2022. Below, I keep the provider’s published label and explain what it refers to. I also separate a daily unlimited limit from a total data allowance, because that difference can matter more than a small price saving.

Check your existing roaming first. If you already have an EU/EEA mobile plan, Hungary may be included under your home allowance, subject to fair-use limits and your contract. Look at the actual allowance in your carrier app before buying another eSIM. The EU roaming guide explains the general rules.

Install your Hungary eSIM before you travel

First check that your exact phone model supports eSIM and is unlocked. Install the profile on reliable Wi-Fi, save the provider’s instructions, and give the line a clear name. At arrival, select it for mobile data and enable roaming on that line if the provider requires it. Disable automatic data switching if you want to avoid your home SIM supplying paid roaming data.

Installation and activation are different steps. Nomad’s selected plans have a 60-day activation window; Airalo’s checked package starts when it first connects to a supported network and has a 365-day connection deadline. Ubigi uses Smartstart at the destination, Holafly starts when you arrive and enable the eSIM, and Jetpac says unactivated packs are available for three months. Follow the instructions for the package in your order. See How to Activate an eSIM or eSIM Not Working? Fix It Here if the connection does not come up.

Hungary networks: Yettel, One and the old names on provider pages

Two confirmed dates make this easier: Telenor Hungary became Yettel on 1 March 2022, and Vodafone Hungary became One on 1 January 2025. These are completed rebrands. They are not evidence that the network quality or roaming permissions of every travel package are identical.

The rebrand dates come from Yettel’s announcement and 4iG’s One announcement. For planning the trip itself, the Visit Hungary official tourism site is useful alongside the network checks below.

Hungary eSIM prices in EUR

These are one-off local Hungary packages, checked on 24 October 2026. A seven-day 10GB plan and a 30-day 10GB plan are not interchangeable if your trip lasts two weeks. Prices are shown before reader coupons, and promotional tiers can move independently.

Nomad eSIM

The selected 20GB fixed and seven-day unlimited packages both list Vodafone and Yettel, allow hotspot and are data-only. Unlimited includes 2GB/day at high speed, then 1Mbps. The checked unlimited package is non-refundable and has no add-ons; the fixed package supports add-ons.

Ubigi

The €9 plan lasts seven days, while the €11 plan lasts 30. Ubigi’s unlimited allowance is measured across the whole plan: 20GB before 2Mbps for seven days, or 30GB before 2Mbps for 15 days. It is not a fresh 20GB or 30GB each day.

Holafly

Holafly now labels the Hungary product unlimited. Its page gives 1GB/day of hotspot sharing and fair-use conditions; unlimited does not mean an unlimited laptop connection. I used the live EUR duration selector, since a separate price table on the same page displayed USD.

Airalo

Airalo also offers intermediate durations. For example, the checked 10GB plan is €17 for seven or 15 days, versus €17.50 for 30 days. Its unlimited package includes 3GB/day at high speed, then 1Mbps. Top-ups and optional renewals should be checked in the selected package rather than assumed for every Airalo product.

Jetpac

Jetpac unlimited prices are €12.50 for three days, €19 for five, €26 for seven, €32.50 for ten, €40 for 15, €47.50 for 21 and €63 for 30. Its policy provides the first 3GB in each 24-hour cycle at standard speed, then up to 1Mbps until the next cycle.

Reader codes: Nomad and Airalo ANDRE15 for 15%; Holafly ANDREONDIGITAL for 5%; Ubigi and Jetpac ANDREONDIGITAL for 10%. Eligibility and exclusions apply. Enter the code and confirm the final total; do not assume it stacks with another promotion.

The five providers: which would I choose?

Budapest, Lake Balaton and countryside coverage checks

I would not assign a guaranteed signal rating to an entire lake shore, wine region or mountain range from a national marketing page. Check the address of your hotel and the roads or villages on your itinerary. Buildings, terrain, congestion, device bands and the selected roaming agreement can all affect the connection.

Use the Yettel coverage map and One coverage map for the networks listed by these plans. Carrier maps are estimates, not a service guarantee. If another carrier looks better for an essential stop, confirm an actual package that offers it rather than assuming a regional eSIM will solve the gap.

Small checks that prevent an expensive mistake

• Check compatibility before purchase. The model name alone may not settle regional device differences. Use the provider’s device list and the phone’s settings. My How to Activate an eSIM walks through the setup.
• Choose validity before price. Ubigi’s €9 10GB package is seven days, not 30. A cheaper short package is not a saving if it expires halfway through the trip.
• Keep your normal number available carefully. These are data-only packages. Check your home carrier’s charges for calls, SMS and roaming before leaving that line enabled.
• Check the currency. These eSIM examples are in EUR; local Hungarian spending uses HUF. Read the exchange rate and fees offered by your card or ATM before accepting conversion.
• Check every border. For Austria, Slovakia or Croatia, verify the exact regional package instead of relying on a Europe label.

FAQ: choosing an eSIM for Hungary

Final verdict: what I would actually buy

For a short Budapest trip, I would first look at the roaming allowance I already pay for. If I needed a separate eSIM, Ubigi’s 10GB for seven days at €9 would be my economical starting point. I would pay €11 for its 30-day version if the dates required it, rather than buying unlimited just because it sounds safer.

For a trip with more photos, tethering or an uneven daily routine, I prefer Nomad’s 20GB for €17.79 as the balanced fixed-data choice. The extra allowance over its 10GB plan costs only €3.56. If I expected to use closer to 30GB or 40GB, Jetpac’s €24 and €28.50 options would go onto the shortlist before I spent more on its own 20GB tier.

Holafly is a different purchase: convenience on the phone, with fair-use conditions and a clear 1GB/day hotspot limit. I would choose it when that arrangement fits, not for a laptop-heavy week. Airalo remains a reasonable choice for someone who values its app and top-ups, but its current 50GB price of €36 is higher than Ubigi’s €34.

Finally, I would check the actual route before paying for a promise of better coverage. The selected network list, the official coverage map and the package rules are more useful than a blanket rural ranking. Match those three things to the trip, apply the eligible code, and confirm the final checkout total.
