MeSIM does not provide a truly unlimited data eSIM for Canada. All of the plans that carry the word “unlimited” in their name give a fixed high‑speed data allowance each day—such as 500 MB/day, 1 GB/day, 2 GB/day, or 3 GB/day—for a set period (e.g., 3 days, 5 days, 7 days, etc.). Once the daily high‑speed limit is reached, the speed is throttled to 512 kbps.
Travelers who need a larger data package can choose MeSIM’s fixed‑data plans, such as the 3 GB/day plan valid for 3 days or the 2 GB/day plan valid for 7 days, both offering high‑speed data until the specified limit is reached before the reduced speed applies.
