eSIM Saily pour Belgium en 2026

Saily has not published which operators it uses in Belgium, so its radio-side reach is unknown rather than necessarily poor. It has also published no breakout location or fastest technology here, leaving traffic routing and the stated network ceiling unspecified. Its large range of plans makes data sizing the main choice, with the risk of buying more than a fortnight needs. Saily does not say whether tethering is available, which matters if a laptop must get online, so that point is worth checking before buying.
