The short answer
AT&T International Day Pass lets your own plan work in Peru with no setup: your number, calls and texts included, charged only for the days the phone is used. At $12 a day, two weeks comes to $168 and a month to $360. Having read both pages, I find Ringo Light far cheaper on a longer trip: unlimited data at full speed for $40.99 for 2 weeks or $56.99 for 30 days. It carries data only.
Unlimited data at full speed for $40.99 (2 weeks) or $56.99 (30 days). One payment, nothing renews. For the same days I count $168 and $360 at the AT&T rate.
The day pass runs on the line you already pay for. Calls and texts work as at home, no eSIM slot is needed, nothing is installed, and you are billed only for the days you use the phone in Peru. I would not dismiss that.

AT&T vs Ringo Light in one paragraph
If you are counting dollars, Ringo Light wins for a Peru trip of a week or more. Two weeks is $40.99 against $168 on the AT&T day pass, and a month is $56.99 against $360. AT&T wins the rest: your own number keeps working, calls and texts are included, nothing needs installing, no eSIM slot is required, and the charge sits on a bill you already pay. I would pick AT&T for a quick trip where convenience beats the saving, or if calls to your own number matter. I would pick Ringo Light for a longer stay where data is the need, such as Cusco and the trip up to Machu Picchu.
Price: the same trip on each
I read AT&T's page on 31 October 2026. It offers the International Day Pass at $12 a day on land, and $6 a day for each additional line used on the same calendar day. The destination list includes Peru but prints no price against it, so $12 is the page's general land rate. Fourteen days of use is $168 and thirty is $360, because the pages show no monthly plan.
Ringo Light is a single payment: $40.99 for 2 weeks, $56.99 for 30 days. That leaves $127.01 in Ringo Light's favor on two weeks and $303.01 on a month. What I notice is how little the month costs beyond the fortnight at Ringo Light, a $16.00 step, while AT&T keeps adding $12 for every extra day of use. There is no one-day Ringo Light plan for Peru, so for a single day of use I would pay for the pass.
The pass is billed per day of use, so a day spent offline in the mountains may cost nothing. In the charts I counted every day as used to keep the comparison simple.
Data: what each one gives you
On land, AT&T describes unlimited talk, text and high-speed data when the pass is added to an eligible unlimited plan, and says coverage and data speed vary by destination and can change. No daily cap is named for land use. If your line is on a smaller plan, I would read the terms for that plan before relying on it.
Ringo Light is unlimited data at full speed for the whole trip, and I like having no daily figure to track. Fair use policy, see Terms.
Calls, texts and your number
AT&T wins this outright, in my reading. The pass runs on your own line, so family, work and your bank reach the number they know, and an SMS code arrives like it does at home.
Ringo Light carries data only. Calls go over apps that use data, and your own SIM stays in the phone for calls. Your number stays on your own SIM next to it, and the eSIM carries only data. For a tour operator or a hotel, I expect WhatsApp to do the job.
Setup and billing
AT&T asks nothing of you. The pass starts when the phone uses data abroad and the days appear on your bill at the end of the billing cycle. Pleasant on arrival, less so when the total shows up weeks later, and I would watch for that.
Ringo Light is bought before you go. The eSIM arrives by email, installs in one scan on home Wi-Fi, and you turn it on for data when you land in Lima. You pay once and nothing renews. Check first that your phone supports eSIM.
What Ringo Light is, and what it is not
I write for Ringo, so here is the plain description of Ringo Light: a data eSIM, sold to fund the full Ringo, one plan that works everywhere. For Peru it sells three trips, all unlimited data at full speed: 7 days at $14.99, 2 weeks at $40.99 and 30 days at $56.99. One payment, nothing renews.
What it is not: it is data only, with no number of its own, so it does not replace the calls and texts AT&T includes. It is not billed by the day, and I would not buy it for a trip of a night or two.

How we compared, and our sources
AT&T, Ringo Light, Ringo Light
We priced AT&T and Ringo Light for Peru on 31 October 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Verizon and T-Mobile. Each has its own comparison page. This one answers a single question, the AT&T day pass or Ringo Light, so it keeps to those two. Left out: A short-trip plan from Ringo Light. Ringo Light sells Peru as 7 days, 2 weeks or 30 days, so there is no weekend chart here. Left out: AT&T cruise rates. The pass has a separate, higher rate at sea, which a trip on land in Peru never touches.
