nextSIM eSIM Data Plans for Belgium

NextSIM does not provide a true unlimited data eSIM for Belgium. All of its plans for the country have fixed data allowances; after the cap is reached the connection speed is throttled, typically to 512kbps for 1 GB/day plans or 2000kbps for 2 GB/day plans.

For travelers who need a larger data budget, fixed‑cap options are available. The eSIM Unlimited Standard 10 Days Belgium plan, for example, offers 1 GB per day for 10 days at a cost of about $14.10 USD, while the eSIM Pro Belgium 200GB 365Days plan supplies 200 GB of data for 365 days at roughly $208.91 USD. These alternatives may be more cost‑effective than a plan that is marketed as “unlimited” but actually imposes a data cap.

nextSIM does not offer Belgium eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available for travelers visiting Belgium.

Users who need voice or messaging can rely on popular VoIP applications such as WhatsApp, Telegram, or iMessage, which work over a data connection and allow calls and messages without a traditional phone number.

nextSIM provides 52 single‑country data plans and 89 multi‑country data plans that include Belgium. The plans are offered in two main formats: fixed data caps, where the amount of data is set for the entire validity period, and daily data caps, which reset each day. Prices for the Belgium options range from about $1.54 to $1, 276.69, with data caps spanning from 1 GB to 200 GB and validity periods that can be as short as one day or as long as 365 days.
