Brussels Airport currently provides free Wi-Fi across the whole terminal, so you have a reliable fallback for tickets or eSIM setup.
Brussels & BRU eSIM guide: land at BRU with your first route already online.
Brussels Airport currently offers free Wi-Fi throughout the terminal, and Brussels Airport-Zaventem railway station sits directly beneath arrivals and departures. Pre-installing mobile data keeps the journey continuous once you board the train. 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.
Direct trains run from the airport station under the terminal to Brussels and many Belgian cities; Brussels-Central is roughly an 18-minute ride on current airport information.
Eligible EU/EEA plans generally receive Roam Like At Home treatment here within fair-use rules.
