nextSIM does not provide a plan with a truly unlimited data cap for Canada. The plans that carry “Unlimited” in the name actually offer a fixed amount of high‑speed data—either 1 GB or 2 GB in total—and after that limit is reached the connection speed is throttled to a reduced speed, such as 512 kbps or 2000 kbps, depending on the specific plan.
Travelers who need more generous data limits can choose from several fixed‑data options. For example, nextSIM sells a 100 GB plan valid for 30 days, and a 50 GB plan available for 30 days for Canada at a lower price. These fixed plans are often more cost‑effective for users who consume large amounts of data, while the “Unlimited” labels simply indicate a capped usage window before speed reduction.
