Airalo does not provide a true unlimited data eSIM for Monaco. All Airalo plans that are titled “Unlimited” actually allow up to 3GB of high‑speed data per day, after which the speed is throttled to 1000 kbps. Because the data cap is capped each day, these plans are not considered unlimited in the sense of continuous high‑speed access without a hard limit.
If an unlimited data experience is preferred, travelers can instead choose a fixed‑data Airalo plan that offers a larger bundle. For example, a 50GB plan is available for 30 days at $35 USD, and a 20GB plan is offered for 15 days at $25 USD and for 30 days at $26 USD. These fixed‑data plans give a larger data allowance before the plan expires and are often a more cost‑effective option for users who need a substantial amount of data while staying in Monaco.
