simpleSIM does not provide an unlimited data eSIM for Central America. All of the plans listed for Costa Rica, Honduras, Nicaragua, Panama, and El Salvador have a hard data cap, with the largest offering 20 GB for 30 days or 365 days, a 10 GB plan for 30 days, and a 5 GB plan for 30 days. Each plan includes tethering and is valid for the stated number of days from first use.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from a truly unlimited option.
