eSIMCard does not provide a genuinely unlimited high‑speed data plan for Monaco. All plans advertised with “Unlimited” in the name actually have a fixed data allowance – for example, the “Unlimited eSIM Data For 1 Day in Monaco” plan gives 1 GB and, after that limit is reached, the speed is reduced to 500 kbps. Similar daily caps apply to the “Unlimited Plus” options, which offer 2 GB for a day but throttle to 2000 kbps after the quota.
For travelers who need more data without speed reductions, eSIMCard offers fixed‑amount plans such as 50 GB or 35 GB for 30 days, which provide consistent 4G/5G speeds throughout the validity period. These fixed plans are typically more cost‑effective for heavy data users.
