ETravelSim does not provide a truly unlimited data plan for Macau. The plans that carry the “Unlimited” label in their name are limited to 1 GB of high‑speed data per day; once that threshold is reached the network speed is throttled to 256 kbps.
Instead, ETravelSim offers fixed‑data eSIMs that give you a larger amount of high‑speed data without any daily ceiling. Examples include the 20 GB plan for 30 days and the 10 GB plan for 30 days, both of which operate at normal speed for the entire validity period. These fixed‑data options may be more cost‑effective for travelers who need a reliable data allowance throughout their stay in Macau.
