nextSIM does not provide a true unlimited high‑speed data eSIM for Colombia. All plans that carry the “Unlimited” label give a fixed amount of 5G or 4G data—typically 1 GB or 2 GB per day—instead of an open data allowance, and once that limit is reached the speed is throttled to 512 kbps or 2000 kbps. Additional data can still be used after throttling, but the connection speed is reduced.
For travelers who need more data, nextSIM offers fixed‑data plans. The eSIM South America 20GB 30Days Economy plan delivers 20 GB of data in Colombia for $59.12, while the eSIM GLOBAL 50GB 30Days Premium plan supplies 50 GB for $1,287.28. These options provide larger data allowances and may be more cost‑effective unless a user is an extremely heavy data consumer.
