eSimfly eSIM Data Plans for Belgium

eSimfly does not offer a truly unlimited data eSIM for Belgium. Plans that carry “Unlimited” in the name provide a capped amount of high‑speed data, such as 1GB per day or 3GB per day. Once the daily limit is reached, the speed is throttled.
For travelers who need more data, eSimfly offers fixed‑amount plans. High‑volume options include 50GB for 30 or 180 days, and lower‑volume plans such as 1GB per day for 30, 60, or 90 days. These fixed data plans can be more cost‑effective for users with heavy data usage.

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 10 single‑country data plans that cover Belgium alone and 55 multi‑country plans that include Belgium. Among these, 19 plans provide a daily data cap that resets each day, while 46 plans offer a fixed data quantity that remains constant throughout the validity period. Prices for the Belgian‑focused plans range from roughly $1.56 to $211.15, and data limits vary between 1 GB and 50 GB, with validity periods spanning from 1 to 365 days.
