nextSIM does not provide a true unlimited‑data eSIM for El Salvador. Every plan that carries the “Unlimited” name is actually capped at a specific amount of high‑speed data and includes a reduced speed that applies once the limit is reached. For instance, the eSIM Unlimited Standard 1 Day El Salvador plan offers 1GB of high‑speed data before the speed drops to 512kbps, and the eSIM Unlimited Plus 1 Day El Salvador plan gives 2GB before throttling to 2000kbps.
Travelers who need more data can choose a fixed‑data plan that offers a larger allowance without throttling. An example is the eSIM GLOBAL 50GB 30Days Premium plan, which delivers 50GB of high‑speed data for 30 days, providing a more cost‑effective option for heavier data users compared with the capped “Unlimited” plans.
