TailSim eSIM Data Plans for Spain

TailSim does not provide a truly unlimited data eSIM for Spain. The plans that carry the word “Unlimited” give 3GB of high‑speed data per day; once that amount is used the speed drops to 1000 kbps.

If you need a larger, unthrottled data allowance, TailSim offers fixed data plans such as 50 GB for 30 days, 20 GB for 30 days, or 10 GB for 30 days, all of which provide the full data amount at the advertised speed for the entire validity period.

TailSim does not provide an eSIM plan for Spain that includes a local phone number or SMS capability. The available offering is data‑only, so travelers would need to rely on VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages. Since some destinations may block or limit specific VoIP services, travelers should confirm that the apps they intend to use are accessible in Spain before purchasing.

TailSim offers 14 single‑country data plans for Spain and 14 multi‑country plans that include Spain. The plans vary in price from $3.99 to $85.50 and in data cap from 1 GB up to 50 GB. Customers can choose between fixed‑data‑cap plans—12 with a set total amount of data—and daily‑cap plans—16 that allow a daily usage limit. Most plans allow tethering and a reduced speed option of 1000 Mbps is available for some.
