A Hungary eSIM installed before departure avoids an arrival setup task; Budapest Airport also has local travel-SIM options if you specifically want to compare them after landing.
Budapest & BUD eSIM guide: land at BUD with your first route already online.
Budapest Airport is directly linked with the city centre by the 100E Airport Express, which currently runs around the clock and requires its own airport-shuttle ticket. Mobile data is useful immediately for the correct stop, ticket information and hotel directions. Pre-installing an eSIM still makes the arrival smoother because your connection can continue when airport Wi-Fi ends and the first transport, ticket or hotel task begins.

Plan around the moments you will actually need data.
The 100E Airport Express runs directly between BUD and central Budapest around the clock; the 200E route connects toward the M3 metro. Check the exact ticket required before boarding.
Eligible EU/EEA plans generally receive Roam Like At Home treatment here within fair-use rules.
