Firsty eSIM Plans for Belgium

Firsty has not published which operators it uses in Belgium, so its radio-side reach is unknown rather than evidence of poor coverage; the practical details to assess are in the table above. Its fastest stated technology is 5G, a ceiling rather than a promise. With a large range of plans, sizing is the main decision, since the risk is buying more data than a fortnight needs. Firsty says tethering is supported, so a laptop can get online, and top-up is available if the allowance runs out. It does not say whether voice is included.
