Yes, Numero eSIM provides several unlimited data plans that cover Belgium. These plans are offered in 3‑, 5‑, 7‑, 10‑, 15‑ and 30‑day options, with prices ranging from $10.03 to $65.74 USD. Each plan delivers unlimited high‑speed data but may be throttled after heavy usage; the maximum speed is capped at 5000 kbps. The data allowance is not tied to a fixed validity period beyond the chosen number of days, meaning users can use the plan as long as the selected validity window is maintained.
If speed reductions after heavy use are a concern, it is recommended to contact Numero eSIM directly to confirm whether a Fair Usage Policy applies and to learn the typical amount of data available at normal speed.
