NextSIM does not provide a truly unlimited high‑speed data plan for Macau. All of the plans labeled “Unlimited” in the catalogue have a fixed data allowance—either 1GB or 2GB for a single day or 1GB/day or 2GB/day for multiple days—after which the connection speed is throttled to 512kbps or 2000kbps, respectively. Because of the speed reduction after the cap, these plans are not considered unlimited in the ordinary sense of unthrottled data.
Users who need larger data volumes without speed restrictions can choose from the fixed data plans. For example, the eSIM Macao 100GB 30Days Economy plan offers 100GB of high‑speed 3G, 4G, and 5G data for 30 days, and the eSIM Macao 50GB 30Days Economy plan supplies 50GB for the same period. Fixed‑data options can be more cost‑effective for travelers who expect to use substantial data while travelling in Macau.
