よくある質問

Does mobile data actually work in the Budapest metro?+

Yes on the platforms and inside stations on the main lines, though it can stutter briefly while the train is running through a tunnel. The safe habit is to buy and activate your BudapestGO ticket above ground before you head down the stairs, since validating one needs a connection at that moment.

Do I need to book the thermal baths from my phone?+

In summer and over long weekends the queues at the well-known baths such as Szechenyi and Gellert get long, and booking a same-day slot online genuinely saves time. That means you need working data while you are out in the city rather than waiting until you are back at the hotel to reserve.

Is Hungary still on the forint, and does paying need data?+

Hungary uses the forint, not the euro. Cards are widely accepted in the cities, but if you pay through a phone wallet or have to approve the transaction in your Thai banking app, that confirmation step needs an internet connection. Keep working data on you rather than relying on finding Wi-Fi at the till.

When does a Hungary eSIM start counting days?+

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

Do I have to remove my home SIM?+

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
