yaySIM does not offer an unlimited data eSIM for Colombia. Every plan listed for Colombia has a hard allowance of 20GB, as shown in the Data cap column of the dataset.
Travelers can choose a fixed data plan that best fits their stay. For example, the CO_20_30 plan provides 20GB for 30 days and costs $50.09 USD, while the GL‑139_20_90 plan gives the same 20GB for 90 days at $92.48 USD. These fixed data options are typically more cost‑effective than paying for data a‑la‑carta, especially for users who consume a large amount of data during their trip.
