Saily’s Belgium eSIM starts at $3.99 for 1 GB. For about a week, the 5 GB plan ($10.99) covers maps, rides and messaging.
The catch: plans are data only, so you get no local phone number for calls or texts.
Belgium is small and well connected by train: Brussels, Bruges, Ghent and Antwerp are all under an hour apart. A Belgium eSIM keeps live train times and maps on your phone from the moment you land.
