Simsima eSIM Data Plans for Belgium

Simsima does not provide a truly unlimited data eSIM for Belgium. The plans that carry the name “Unlimited” in their titles actually offer a fixed allowance of 3GB per day and, once that limit is reached, the speed is reduced to 1 000 kbps. Because of the daily cap and throttle, these plans are not considered unlimited high‑speed data.

If you need a large amount of data without daily limits, Simsima offers fixed‑data alternatives instead. For example, a 100 GB plan valid for 180 days or a 50 GB plan valid for 30 days are available for Belgium. These fixed‑data plans give you a set amount of high‑speed data for the entire validity period and may be more cost‑effective if you are a heavy data user.

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 offers 9 single-country plans and 27 multi‑country plans for travelers in Belgium. The plans span a price range from about $3.91 to $171.84 and provide data amounts between 1 GB and 100 GB, with validity periods of 5 to 180 days. Some of the offerings allow a fixed data cap while a smaller portion provides a daily data cap, giving travelers flexibility depending on their usage habits.
