eSIMCard does not provide any truly unlimited high‑speed data plans for El Salvador. All of the plans that use “Unlimited” in their name actually contain a fixed data allowance—typically 1 GB for a day or 2 GB per day for longer validity periods—after which the connection is throttled to 500 kbps or 2 Mbps. This means the data is not unlimited; it is capped before the speed reduction applies.
Travelers who need more data can choose from the fixed‑data plans that eSIMCard offers, such as the 50 GB plan for 30 days or the 100 GB plan for 180 days. These options provide larger high‑speed data allowances without the speed reduction that comes with the “Unlimited” branded plans. Selecting a fixed‑data plan may be more cost‑effective for heavy data users compared to the capped unlimited‑label options.
