The short answer
Spain is on AT&T's International Day Pass list, so an AT&T phone can work in Madrid or Barcelona with no preparation, for $12 on each day it is used. Over two weeks that is $168, and over a month $360. Ringo Light is unlimited data at full speed for $8.99 for 3 days, $16.99 for 2 weeks or $26.99 for 30 days. The eSIM is far cheaper for anything beyond a short stop, and AT&T is the one that carries your calls and texts. I would pick the eSIM for a week or more.
Unlimited data at full speed: $8.99 for 3 days, $16.99 for 2 weeks, $26.99 for 30 days, paid once. The same days on the AT&T pass come to $36, $168 and $360.
The pass rides on the line you already have. Calls and texts behave as at home, no eSIM slot is needed, nothing gets installed, and the days used show up on a bill you already pay.

Fourteen days of the AT&T pass at $12, $168 in total, against Ringo Light for 2 weeks.

The short answer for Spain
Money first, as I read it. A fortnight on the AT&T pass is $168 and a month is $360; Ringo Light covers the same stretches for $16.99 and $26.99. Even three days favors the eSIM, $8.99 against $36. The pass is still the better buy, in my view, in two situations: a stopover of a day, where you would rather pay for that one day and do nothing beforehand, and any trip where people must reach you on your own number. Everything else, from a week of tapas and trains to a month in Valencia, is cheaper on Ringo Light.
Price, trip by trip
I read AT&T's International Day Pass page on 31 October 2026. It prices the pass at $12 a day on land, with $6 for each additional line used on the same calendar day. I found Spain on its destination list. A 24-hour pass begins when the phone first uses data, sends a text or places a call, and a new fee applies only once that period ends and the phone is used again. Fees are charged at the end of the billing cycle. No monthly plan is shown, so a month is 30 times the daily rate.
Ringo Light is paid once per trip, in dollars. Against the pass it saves $27.01 over a long weekend, $151.01 over two weeks and $333.01 over a month. Days when the phone sits in airplane mode are not billed by AT&T, so I treat the totals above as the ceiling for a trip where the phone is on every day, which is the usual way people travel with a map and a ticket app open.
Data and speed
I read AT&T's description of the pass as unlimited data on land when it is added to an eligible unlimited plan, and it sets a lower allowance only for cruise use. On a plan that is not an eligible unlimited plan the terms differ, so I would check your own line before relying on it.
Ringo Light is unlimited data at full speed for the length of the trip you buy, nothing to track from one day to the next, which is what I want from a holiday plan. Fair use policy, see Terms.
Your number, calls and texts
Here AT&T has the advantage, and I count it as a large one. Your regular number keeps ringing, texts arrive in the same thread as always, and calls to Spain, to other included destinations and back to the US carry no added charge on an eligible unlimited plan, per the page.
Ringo Light does none of that. It carries data only, so calls ride on WhatsApp, FaceTime or similar apps, and your own SIM stays in the phone to receive bank codes and ordinary texts. Your number stays on your own SIM next to it. A restaurant in Seville that wants to call you back on a normal number will reach the AT&T line, not the eSIM.
Setup and billing
With AT&T there is no step before you fly, and I admit that is tempting. You land, the phone finds a network, and the day is logged. The cost is that nothing warns you how fast it adds up: a busy fortnight is a three-figure line on the next statement.
Ringo Light is a purchase made at home. The eSIM arrives by email, one scan installs it on Wi-Fi, and you turn on its data when the plane lands in Madrid or Barcelona. The phone needs eSIM support; the AT&T pass works on any phone your plan covers.
What Ringo Light is, and what it is not
Ringo Light is the data eSIM Ringo sells to fund the full Ringo, one plan that works everywhere. For Spain it offers three trips, each with unlimited data at full speed: 3 days at $8.99, 2 weeks at $16.99, 30 days at $26.99. One payment, no renewal.
It is not a phone line, and I would not let anyone think it is. There is no number of its own and no calling plan, and it is not billed by the day used. If you need your AT&T number to work for calls, keep using it, or run both together.
