nextSIM eSIM Data Plans for El Salvador

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.

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 lists 18 single‑country plans that include El Salvador, covering 1 GB to 50 GB of data and priced from about $5 up to $1,287. In addition the service offers 36 multi‑country plans that bundle El Salvador with other destinations; those plans also range from 1 GB to 50 GB and cost roughly the same as the single‑country options. The single‑country plans are fixed data amounts, while many multi‑country options provide a daily data cap, giving travelers the choice between a set total quantity of data or a per‑day allowance.
