Yes. Coverage is excellent around the resorts and beaches of Lake Balaton (the "Hungarian Sea"), allowing you to share summer holiday photos instantly. 

 Generally yes. You will have signal in the outdoor pools of Széchenyi or Gellért baths, though thick walls may block connection in deep indoor steam rooms. 

 Yes. Our eSIM connects to strong local networks ensuring reliable coverage while touring vineyards and cellars in the Tokaj or Eger countryside. 

 Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing. 

Yes, 100%. Buying a physical local SIM card (like Magyar Telekom or Yettel) at Budapest Airport requires you to find the kiosk, wait in line, and go through a mandatory passport registration process as required by EU law. Our eSIM is 100% digital, requires no ID registration, and can be installed before you fly, so you are connected the moment you land. 

Yes, absolutely. Bolt and Uber are essential apps for getting around Budapest. Our eSIM provides high-speed, low-latency data, which is crucial for ordering a car from the airport (BUD), tracking your ride, and using Google Maps to navigate the city's public transport system. 

 This specific plan is valid only within Hungary (and the EU). This is the most important question for "Euro-trip" travelers. If you take a train from Budapest to Belgrade (Serbia) or Ukraine, your connection will stop at the border as they are not in the EU. For this multi-country trip, we highly recommend our Europe Regional eSIM, which covers both EU and non-EU Balkan countries. 

It depends. Hungary is in the EU, so "Roam Like at Home" applies only to EU citizens.

• If you are from the UK (Post-Brexit): Most UK carriers (like O2, Vodafone, Three) have reintroduced daily roaming fees (e.g., £2-£6 per day).
• If you are from the USA/Canada/Asia: Your home carrier will charge expensive international rates (e.g., $10-$14 per day).

A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper than these roaming charges.
