Astaroam does not provide a plan that offers unlimited high‑speed data on the Isle of Man. The plans labeled “Unlimited – 3 days”, “Unlimited – 5 days”, “Unlimited – 7 days”, and “Unlimited – 10 days” all give the traveler 3GB per day, after which the speed is throttled to 1000kbps, so the data allowance is capped.
For travelers who need larger data allocations, Astaroam sells fixed‑data plans for the Isle of Man. Examples include the Isle of Man 20GB 30Days plan at $16.78, the Isle of Man 10GB 30Days plan at $10.58, and the Isle of Man 5GB 30Days plan at $6.81. If coverage outside the Isle of Man is desired, Europe 10GB 30Days ($21.90) and Europe 5GB 30Days ($13.11) are available and also include the Isle of Man in their network. Fixed data plans can be a more cost effective choice unless a user requires truly unlimited data.
