Eskimo eSIM does not provide an unlimited data eSIM for El Salvador. All of the plans available for this destination have a fixed data allowance, ranging from 3GB up to 30GB, with a validity of 730 days in each case.
If you require a larger data volume, you can choose one of the fixed plans such as the Global eSIM 30GB (2 years) at $90.00 USD or the Global eSIM 10GB (2 years) at $39.00 USD. These plans offer substantial data allowances and include tethering, but they are not unlimited. Selecting a fixed data plan may be more cost‑effective unless you are an extremely heavy data consumer.
