nextSIM eSIM Data Plans for Spain

nextSIM does not supply a truly unlimited data eSIM for Spain. All plans labeled “Unlimited” in the catalog have a data cap of either 1GB or 2GB and include a reduced speed of 512kbps or 2000kbps after the limit is reached. Instead, nextSIM offers fixed‑data plans that give a higher, continuous data allowance.

For travelers who need a larger amount of high‑speed data, nextSIM provides fixed‑data options such as 100GB for 30 days or 50GB for 30 days, which allow the full data amount to be used at normal speed throughout the validity period. These plans are generally more economical if the user is a heavy data consumer.

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.

nextSIM lists 33 single‑country plans and 48 multi‑country plans available for use in Spain. The catalog includes both daily data cap offerings, which limit the amount of data you can use each day, and fixed data cap options, which provide a set amount of data for the entire validity period. Prices run from as little as $1.38 up to $1, 275.10, with data allowances ranging between 1 GB and 100 GB.
