ZenSim does not offer a true unlimited data eSIM for Macau. All plans that carry the word “Unlimited” actually provide a 3GB/day high‑speed allowance and cease to be unlimited once that daily cap is reached.
Travelers who need a larger data allotment can choose from ZenSim’s fixed‑data plans for Macau, such as a 20GB plan valid for 10 days at $30.00 USD or a 20GB plan valid for 30 days at $35.00 USD. A smaller 10GB 10‑day plan is also available at $18.00 USD. These fixed‑data options give users a larger amount of high‑speed data in a single package, but they are not unlimited.
