Saily does not currently provide a genuinely unlimited data eSIM for El Salvador. The plan titled “Global UNLIMITED 30 days” actually carries a data cap of 30 GB; after this limit is reached the speed is throttled to 1024 kbps. Because of the cap, the plan is not truly unlimited for high‑speed usage.
Travelers who need high‑speed data in El Salvador can choose from Saily’s fixed‑data plans. For example, the “El Salvador 10GB 30 days” plan offers 10 GB of high‑speed data for 30 days at $45.99 USD, and the “El Salvador 5GB 30 days” plan gives 5 GB for 30 days at $27.99 USD. A longer‑validity option is the “Global 20GB 365 days” plan, which supplies 20 GB for a full year at $66.99 USD. These fixed‑data options may be more cost‑effective for travelers who are moderate to heavy data users.
