Wiiline does not provide any high‑speed data plan that is truly unlimited for Monaco. The plans that carry the word “Unlimited” in their name give a fixed allowance each day (for example 1 GB/day or 2 GB/day) and once that daily quota is reached the connection speed is throttled. Because the data cap is a hard limit before throttling kicks in, these plans are not unlimited in the sense of unlimited high‑speed data.
Travelers who need a larger amount of data can instead choose one of Wiiline’s fixed data plans. Examples include a 200 GB 30‑day plan, a 100 GB 30‑day plan, a 50 GB 30‑day plan, or a 35 GB 30‑day plan that also includes local calls. Each of these plans allows continuous high‑speed data until the allotted amount is used up, after which the plan simply ends.
