nextSIM does not provide a truly unlimited data eSIM for Macau. All plans listed under the "Unlimited" name have a fixed data allowance that is fully active for a specified number of days, after which the speed is reduced – for example, the eSIM Unlimited Standard 1 Day Macao plan provides 1 GB of high‑speed data, then drops to 512 kbps. Because each “Unlimited” plan has a hard cap (1 GB or 2 GB per day), they are not unlimited in the sense of offering unrestricted high‑speed data.
If an unrestricted data volume is preferable, nextSIM offers fixed‑data plans such as the eSIM 100GB 30 Days Macao and eSIM 50GB 30 Days Macao. These plans give larger data allowances for the same 30‑day validity, though they do not carry the “Unlimited” label. Selecting a fixed‑data plan can be more cost‑effective for heavy users who need consistent high‑speed internet in Macau.
