The best eSIM for Americans in Spain in 2026.

Roam with your carrier, or buy an eSIM

Spain is on the destination list for both AT&T and Verizon, so your phone can work in Madrid or Barcelona the minute you land. AT&T's International Day Pass and Verizon's TravelPass both cost $12 a day in Spain, which is $36 for three days, $168 for two weeks and $360 for a month. I read both pages on 31 October 2026, and both charge only for days on which the phone is used there.

Both carriers come to $168 for two weeks and $360 for a month of daily use, where Ringo Light is $16.99 for 2 weeks and $26.99 for 30 days, and for three days it is $36 against $8.99. That leaves Ringo Light $27.01 under either pass for a long weekend, $151.01 for a fortnight and $333.01 for a month. Among the travel eSIMs, Ubigi is the nearest rival at $34 for 15 days and $44 for a month.

What you get from the carrier is your own number ringing, calls and texts inside the pass, and nothing to set up before the flight. For one day in Madrid between flights, I would roam. A phone left in airplane mode on some days is not billed on those days, so I treat the totals above as the ceiling for a trip where the phone is on every day.

From the second day the eSIM is the cheaper choice. One pass day is $12, and Ringo Light's 3 days is $8.99, so a three-day weekend costs $36 on the pass, about four times as much.

Networks in Spain, and what changes for an American visitor

Spain has four networks, Movistar, Orange, Vodafone and Yoigo, and the brands rent different ones. Holafly lists all four. Airalo rides Yoigo, Vodafone and Orange, Saily Movistar, Orange and Vodafone, Nomad Movistar and Orange, and Ubigi Orange only. I would not pick on coverage for the cities, the coast or the islands.

The passes bill differently. AT&T starts a 24-hour pass the first time the phone uses data, sends a text or places a call, and adds the fee to your bill at the end of the billing cycle. Verizon gives 5 GB of high-speed data in each 24-hour session, then data continues at 3G speeds for the rest of it, and extra fast data is offered for $10 for 2 GB by replying "speed".

The AT&T page I read describes unlimited data on land when the pass is added to an eligible unlimited plan, so I would check your own line first. Calls inside Spain and back to the United States are included on an eligible plan per the AT&T page, and per the Verizon page too, so a restaurant in Seville can ring your usual number.

If you want a data bucket: Ubigi or Airalo

• Ubigi, $12 for 10 GB. The cheapest 10 GB for 30 days, with 25 GB at $19. It runs on Orange only.
• Airalo, $14 for 10 GB. Its 20 GB at $20 is the cheapest 20 GB, $6.99 under Ringo Light's month. The Guay plan rides Yoigo and Vodafone.
• Nomad, $14 for 10 GB. 20 GB costs $21, on Movistar and Orange, and you manage it in the Nomad app.
• Saily, $15.99 for 10 GB. It has the cleanest app and sells 20 GB at $22.99. Its listing is dated 4 October 2026, and saily.com would not load when I tried it.
• ✓Ringo Light, no buckets. Its 2 weeks is unlimited at $16.99 and its 30 days unlimited at $26.99. If you want 10 GB to last a month, I would buy Ubigi at $12, and Airalo sells 20 GB for $20.

What Ringo Light is

Ringo Light is the data eSIM of Ringo, the company I write for, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Spain it sells three trips, all unlimited data at full speed: 3 days at $8.99, 2 weeks at $16.99 and 30 days at $26.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, with no app.

The eSIM sits beside your own SIM, which keeps your number for calls and texts. Both carrier pages say calls and texts come with the pass, so if you leave roaming on for them I would first read how your carrier bills a day of use.

The card to buy it is further up this page, just after the side-by-side table.
