MeSIM does not provide a truly unlimited data eSIM for Colombia.
All of its plans that are marketed as “unlimited” give a fixed amount of high‑speed data per day—such as 500 MB/day, 1 GB/day, 2 GB/day, 3 GB/day or 5 GB/day—and when that daily quota is reached the speed drops to 384 kbps.
If you need a larger data allowance, MeSIM offers fixed data plans. For example, a 3‑day plan with 5 GB/day for $27.49 USD and a 7‑day plan with 3 GB/day for $35.99 USD are available for use in Colombia. These fixed‑data options can be more cost‑effective for travelers who anticipate heavy data usage, while still ensuring predictable performance.
