MobileSIM eSIM Data Plans for Spain

MobileSIM does not provide a truly unlimited data eSIM for Spain. The plans that include “Unlimited” in their name actually offer 3 GB of high‑speed data per day; once that daily allowance is exhausted the speed is reduced to 1000 kbps. For travelers seeking more data without daily limits, MobileSIM offers fixed‑data plans such as a 20 GB plan for 30 days or a 10 GB plan for 30 days, which may be more cost‑effective for moderate to heavy usage.

MobileSIM does not provide Spain eSIM plans that include a phone number or SMS capability. The only options available for Spain are data‑only eSIMs, which give you high‑speed internet access but no voice or text services. Travelers who need to make calls or send messages can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage, which work over the data connection.

MobileSIM lists 12 single‑country data plans and 10 multi‑country plans that include Spain. The single‑country plans provide a fixed data amount that ranges from 200 MB to 60 GB and are priced between $2.30 and $165.00, giving flexibility for short trips or longer stays. The multi‑country plans offer similar data caps but allow validity across several regions, also falling within the same price and data range. The provider distinguishes between fixed data‑cap plans (where a set amount of data is allocated for the entire validity period) and daily‑cap plans (where a limited amount of data is available each day), allowing travelers to choose the structure that best fits their usage patterns.
