Keep your Irish number live

Download offline maps first

Watch your data usage
The HelloRoam app shows how much data you've used, though it can be up to 3 hours behind. On a fixed-data plan, HelloRoam also emails you when your data runs low, so there are no nasty surprises. Top up inside the app if you need more data in Budapest, no reinstall needed.
Save emergency numbers offline
The emergency number in most countries is 112. In Budapest it is worth checking the local number too. Save these offline before you travel. Your phone can call an emergency number on any available mobile network, even with no data left on your plan. The HelloRoam eSIM itself is for data only.

HelloRoam eSIM vs Irish carrier roaming in Budapest
Your connectivity options for a trip to Budapest from Ireland. Compare HelloRoam eSIM plans against buying a local SIM card or using your Irish carrier's roaming add-on.
| Category | HelloRoam eSIM | Local Budapest SIM card | Roaming with your carrier |
|---|---|---|---|
| Typical cost | From €1.91 total | — | — |
| Details | Plans from €1.91. Buy before your flight from Dublin Airport, activate at home over Wi-Fi, and arrive at Budapest Ferenc Liszt International Airport already on local 4G LTE data. No store visit, no ID check, and no wasted time after a long flight. | Available at Budapest Ferenc Liszt International Airport but requires setup time after your flight. Tourist SIMs may need passport registration and in-store activation. Unused data is usually forfeited when your trip ends. | Outside the EU, roaming on an Irish plan usually costs extra, often as a daily add-on that builds up over a longer trip. Budapest is in the EU, so your Irish plan's EU roaming allowance covers it, but check how much data that allowance gives you. HelloRoam eSIM plans start from €1.91, and you can choose more data or a longer validity for a longer stay. |

Best time to visit Budapest from Ireland
Budapest is a popular destination for Irish holidaymakers. Dublin Airport has regular direct or connecting flights year-round. The best time to visit depends on your preferences for weather, crowds, and value.

Airport and Transit Connectivity
Budapest Ferenc Liszt International Airport (BUD) has 4G and 5G coverage across Terminals 2A and 2B. Your HelloRoam eSIM connects to the network as soon as you land.
The 100E express bus from the airport to Kalvin ter metro station takes about 30 minutes and has consistent 4G coverage the whole route. The BKK metro, tram, and bus network all have 4G at outdoor stops. The M4 metro line, which is the newest, has the best tunnel coverage.
The older M3 blue line, which is under renovation, has more frequent signal gaps in tunnels. Trams along the Danube (lines 2 and 19) have strong outdoor signal all the way to Batthyany ter. Irish travellers should activate their eSIM before boarding so navigation apps work as soon as they land.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer

Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
