Saily eSIM Data Plans for Belgium

Saily does not provide a truly unlimited high‑speed data eSIM for Belgium. The plans that carry the “UNLIMITED” name are fixed‑data plans: for example the Belgium UNLIMITED 10‑days plan grants 5GB/day (10 days total) and the Belgium UNLIMITED 20‑days plan offers 5GB/day (20 days). After the cap the speed is reduced to 1000kbps. Similarly, the Global UNLIMITED 30‑days plan provides a 30GB allowance for 30 days, also throttled after the limit is reached. Offers with high data allowances are available, but none give unlimited high‑speed access.

Saily does not provide a Belgium eSIM plan that includes a phone number or SMS capability. Only data‑only packages are available from the provider for that destination.

Travelers can still communicate over the Belgian network using data‑dependent VoIP applications such as WhatsApp, Telegram, or iMessage, but some destinations may block or restrict access to particular apps or services. It is advisable to verify that the applications you rely on are reachable in Belgium before purchasing a plan.

Saily offers a total of 32 data plans for Belgium, comprising 10 single‑country plans and 22 multi‑country plans. The plans vary in price from $3.99 to $159.99 and in data cap from 1 GB to 50 GB. Saily’s catalogue includes both fixed‑amount plans—21 of them provide a set data bundle for the full validity period—and daily‑cap plans, 11 of which reset the data allowance each day, allowing users to control daily usage.
