eSimfly eSIM Data Plans for Belgium

eSimfly does not provide a true unlimited data eSIM for Belgium. The plans that carry “Unlimited” in their name actually contain fixed daily limits, such as 1 GB per day on short‑term plans or 3 GB per day on longer‑term options, and the data allowance is capped. After the cap is reached, the speed is reduced to a lower rate. For travelers who need high‑volume data, eSimfly offers fixed‑cap alternatives such as a 50 GB plan for 30 days or a 30 GB plan for 30 days, which cover Belgium and many other European countries. These fixed plans can be more cost‑effective unless a user requires continuous high‑speed data without any limits.

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 9 single‑country plans and 55 multi‑country plans for Belgium, giving travelers a wide selection of options. The available plans span a price range of about $1.56 to $162.42 and offer data caps from 1 GB up to 50 GB. Within these offerings, some plans use a daily data cap—providing a set amount of data each day—while others employ a fixed data cap, giving a total data allowance valid for the plan’s entire period.
