nextSIM labels its “Unlimited Standard” and “Unlimited Plus” plans as unlimited, but each of these plans has a data cap: the Standard plans provide 1 GB per day and the Plus plans provide 2 GB per day. Once the allotted data is used, the network speed drops to 512 kbps for Standard or 2000 kbps for Plus, so the data is not truly unlimited.
For travelers who need more high‑speed data, nextSIM offers fixed‑data plans that might be more suitable. For example, the 100 GB 30‑day plan costs $59.29 USD, and a 50 GB 30‑day plan is available for $35.83 USD. These fixed plans give a large data allowance without any post‑limit speed reduction and can be more cost‑effective for heavy data users.
