Simsima does not provide a truly unlimited data eSIM for Belgium. All plans carry a data cap, typically 3 GB per day, after which the speed is reduced to 1000 kbps. Because of this limitation, travelers who need unrestricted high‑speed data will find no plan that meets that criterion.
Instead, Simsima offers a range of fixed‑data options. For example, a 100 GB plan valid for 180 days is available for €224, while a 50 GB plan for 30 days costs about €45. A 20 GB plan for 30 days is priced around €18. These higher‑capacity plans can be more economical for users who consume a lot of data compared to paying for a short‑term “Unlimited” plan that still imposes a daily cap and post‑cap throttling.
Simsima does not offer Belgium eSIMs that include a phone number or SMS capability. The provider only sells data‑only eSIMs for Belgium. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls or send messages.
Simsima provides 30 single‑country data plans for Belgium and 25 multi‑country plans that include Belgium. The single‑country plans allow you to buy data specifically for use only in Belgium, while the multi‑country plans give access in Belgium along with other destinations in the SIM’s coverage area. Among these plans Simsima offers both daily data cap options and fixed data cap variants; the daily‑cap plans reset the allowance each day, whereas the fixed‑cap plans allocate a total amount of data for the entire validity period. Prices across all plans range from about $3.10 to $452.76, and data caps vary from 500 MB up to 100 GB, providing options for a wide range of usage needs.
