Simsima eSIM Data Plans for Belgium

Simsima does not provide a true unlimited data eSIM for Belgium. The plans that carry the word “Unlimited” in their name actually give 3GB of high‑speed data per day and then throttle the speed to 1000kbps after that daily limit is reached.

Travelers who need more data can choose from Simsima’s fixed data plans, such as the 50GB plan valid for 30 days or the 20GB plan also valid for 30 days. These plans offer a larger, fixed amount of high‑speed data and may be more cost‑effective for most users unless they are extremely heavy data consumers.

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.
