nextSIM eSIM Data Plans for Spain

No, nextSIM does not provide a true unlimited data eSIM for Spain. All plans labeled “Unlimited” in the nextSIM catalogue actually cap the high‑speed data at 1 GB (either per day or over the validity period) and reduce the speed to 512 kbps or 2000 kbps once the limit is reached.

If you need more data, nextSIM offers fixed‑data plans such as the 50 GB 30‑day or 100 GB 30‑day eSIMs for Spain. These provide a large high‑speed allowance without throttling, and can be more cost‑effective unless you are an extremely heavy data user.

nextSIM does not provide any eSIM plans for Spain that include a phone number or SMS capability; all plans available from the provider are data‑only.

Travelers who need to send or receive text messages or make calls can use internet‑based messaging and voice apps such as WhatsApp, Telegram or iMessage, which work over the data connection provided by nextSIM.

In Spain nextSIM provides a total of 34 single‑country data plans and 45 multi‑country data plans. These packages cover a price range from about $1.67 to $1,278.92 and a data range from 1 GB up to 100 GB, with validity periods that can be as short as one day or as long as a year. Some plans use a fixed data amount, giving customers a set total of data for the entire validity period, while other plans use a daily data cap that resets each day, allowing travelers to spread their usage across multiple days.
