nextSIM eSIM Data Plans for Spain

nextSIM does not provide a true unlimited‑data eSIM plan for Spain. All of its plans that carry “Unlimited” in the name actually give a fixed amount of high‑speed data each day— 1 GB/day or 2 GB/day—after which the speed drops to 512 kbps or 2 Mbps.
If a traveler needs a larger data allowance, nextSIM offers fixed‑data options that may be more cost‑effective for heavy use. For example, the 50 GB plan valid for 30 days costs $198.95, and a 50 GB plan for a full year is available for $121.41. These plans provide ample data without the speed reductions found in the “Unlimited” options.

nextSIM does not provide eSIM plans for Spain that include a local phone number or SMS capability; all offerings from this provider are data‑only. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging.

nextSIM provides a variety of data plans that cover Spain.
Within its catalog the carrier offers 21 single‑country plans and 36 multi‑country plans that include Spain.

The plans vary widely in price—from about $1.64 for a 1 GB option up to roughly $1,287.33 for a 50 GB option. Their validity periods range from a single day to a full year, allowing travelers to choose a plan that matches the length of their stay.

Some plans are structured around a fixed data amount, while others apply a daily data cap (for example, 512 MB or 2 GB per day) to help manage balance between consumption and local roaming speeds. This mix gives travelers flexibility between high‑cap, long‑term data bundles and more controlled, day‑by‑day access.
