nextSIM eSIM Data Plans for Belgium

nextSIM does not provide a true unlimited data eSIM for Belgium. All of the plans that carry the word “Unlimited” in their name actually offer a fixed data allowance—typically 1GB per day or 2GB per day for a single day—and after the limit is reached the speed is throttled to 512kbps. This means that the high‑speed data is still capped, so the plans are not unlimited in the sense of providing unlimited high‑speed data without a limit.

If you need more data for your stay in Belgium, you can choose a fixed‑data plan that offers a larger total allowance. For example, the eSIM Unlimited Standard 10 Days Belgium plan gives 1GB per day for 10 days, costing $14.09, while the eSIM 100GB 30 Days Belgium plan delivers 100GB of data for a month for $61.37. These fixed‑data options give a higher total data allowance and can be more cost‑effective for heavy data users.

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 a range of plans in Belgium that include both single‑country and multi‑country options. In Belgium you can find 52 single‑country plans and 89 multi‑country plans. The plans cover prices from $1.54 to $1, 295.18 and data caps between 1 GB and 200 GB, with validity periods ranging from 1 to 365 days. Plans are offered in two main types: fixed data‑cap packages, which give you a set amount of data that does not change, and daily data‑cap packages, which allow you to receive a daily data allowance that is aggregated over the plan’s validity. This variety enables travelers to choose the balance of price, data volume, and coverage that best matches their needs.
