eSimfly eSIM Data Plans for Belgium

eSimfly does not provide a truly unlimited data eSIM for Belgium. Every plan that carries the word “Unlimited” in its name actually offers a fixed amount of high‑speed data—typically 1GB per day or 3GB per day for multi‑day bundles—and after that threshold is reached the speed is reduced, although the exact throttled speed is not disclosed. For travelers who need more data without daily limits, eSimfly offers fixed‑data plans that may be more cost‑effective, such as the Belgium 100GB 30 days plan or the Belgium 50GB 30 days plan, which provide a large high‑speed data allowance for the stated validity period. These plans are alternatives when a user requires substantial data usage in Belgium.

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 offers a broad range of data plans that include Belgium. For single‑country coverage, there are 25 plans that list Belgium as the only covered country, while in the multi‑country portfolio Belgium is included in 73 plans that bundle several destinations. The available plans span a price range from about $1.08 to $331.48 and cover data caps between 1 GB and 100 GB. Within these options, plans are divided into fixed data‑cap plans (the majority, 69 plans) and daily data‑cap plans (29 plans), giving travelers flexibility to choose either a fixed amount of data for the duration of the plan or a daily cap that allows the data to refresh each day.
