nextSIM eSIM Data Plans for El Salvador

nextSIM does not offer a truly unlimited high‑speed data eSIM for El Salvador. The plans that carry “Unlimited” in their name provide 1GB or 2GB of 3G/4G high‑speed data; once the limit is reached, the speed is throttled to 512 kbps or 2000 kbps.

Travelers wanting more data without a speed downgrade can choose the fixed‑data plans. For example, the eSIM 100GB 30 days plan is available for $205.87 USD, and the eSIM 50GB 30 days plan is $105.58 USD. These plans offer a larger data allowance and maintain normal speeds throughout the validity period.

nextSIM does not provide an El Salvador eSIM that includes a phone number or SMS capability. The only plans available from nextSIM for El Salvador are data‑only eSIMs. Travelers who need to make calls or send text messages can rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and do not require a local phone number or the ability to receive SMS.

nextSIM offers 26 single‑country data plans for El Salvador and 36 multi‑country plans that include El Salvador as part of a broader regional package.
The single‑country plans range in price from $4.96 up to $1, 275.10 and in data cap from 1 GB to 100 GB, with validity periods between 1 and 30 days.
The multi‑country plans fall into the same price and data ranges, but they allow coverage across several countries for the same duration.

There are also 30 plans that feature a daily data cap (data is limited each day) and 32 that offer a fixed data amount (the total data is available for the entire validity period). Daily‑cap plans are useful for travelers who need predictable usage each day, while fixed‑cap plans give a larger burst of data to use over the period.
