eSimfly eSIM Data Plans for Belgium

eSimfly does not provide a truly unlimited data eSIM for Belgium. The plans that carry the word “Unlimited” give a fixed high‑speed allowance of 1 GB per day and, after that limit is reached, the speed is reduced. If a traveller wants a larger high‑speed data allocation, eSimfly offers fixed data plans such as the Belgium 100 GB 30 days plan or several 50 GB options (30‑day or 180‑day validity). For users who consume large amounts of data, a fixed‑data plan can be more cost‑effective than the daily‑based “Unlimited” options.

eSimfly does not provide Belgium eSIM plans that include a phone number or SMS capability; only data‑only eSIMs are available from the provider. Those data‑only plans give access to the internet via 5G, 4G or 3G networks, but they do not offer inbound or outbound voice or text services.

Because a phone number is not supplied, travelers can use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages. These services work without a traditional phone number or SMS functionality.

eSimfly lists 19 single‑country plans that include Belgium. These plans span the standard data range of 1 GB to 100 GB and are priced between about $1.50 and $348.94, giving travellers a flexible choice of data quantity and price.
In addition, Belgium can be selected as part of eSimfly’s 60 multi‑country plans. Those multi‑country offers typically combine several European destinations, offering validity periods from 1 to 365 days and available either as fixed data‑cap bundles (where a total amount of data is supplied for the entire period) or daily‑data‑cap bundles (where a set data allowance is granted each day).
Thus, for Belgium eSimfly provides both a set of 19 single‑country data plans and a broader range of 60 multi‑country plans, covering the full spectrum of data caps and pricing.
