Simsima eSIM Data Plans for Belgium

Simsima does not provide a truly unlimited data eSIM for Belgium. All of the plans billed under the “Unlimited” names give a fixed allowance of 3GB per day, after which the speed drops to 1 Mbps. If a traveler needs more data without a speed reduction, they can choose one of the fixed data plans such as 50 GB for 30 days, which offers 50GB of high‑speed data for 30 days, or a 20 GB plan for 30 days. These fixed‑data options can be more cost‑effective for heavy data users.

Simsima does not offer Belgium eSIM plans that include a phone number or SMS services. All eSIM options available for Belgium from this provider are data‑only, so travelers cannot use the eSIM for traditional voice calls or receive or send SMS text messages. However, they can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, provided these services are not blocked or restricted in Belgium. It is advisable to verify that the required apps are accessible in the destination before purchasing a data‑only eSIM.

Simsima currently lists 10 single‑country data offerings for travelers in Belgium, and an additional 28 plans that cover multiple countries simultaneously. The single‑country options typically provide fixed data amounts, such as 1 GB or 2 GB packages, valid for a set period ranging from a few days to a full year. The multi‑country selections are more flexible, offering larger data caps, often up to 50 GB per month, and can be used across a network of partner European zones. Prices for both categories vary from roughly $4 USD for the smallest packages up to around $105 USD for the most generous plans, while the data caps span from 1 GB to 50 GB across the spectrum of available bundles.
