Alodata does not provide a truly unlimited data eSIM for travellers staying in Monaco. The plans that carry “Unlimited” in their name actually grant a fixed high‑speed allowance of 1 GB per day; once this limit is reached the speed is throttled to 1280kbps.
Instead, alodata offers fixed‑data plans that can cover most travel needs. For example, a 100 GB plan for 90 days costs $256.00 USD, while a 50 GB plan for 90 days is available for $150.00 USD. Both plans include tethering and are usable on 4G and 5G networks in Monaco and across multiple countries. Choosing one of these fixed‑data options is typically more cost effective for most users unless they require very heavy data usage.
