Unlimited eSIM Peru: Five Sellers, One Word, No Standard

Every seller in this market offers a Peru eSIM called unlimited, and four of them mean four different things by it. One caps you at three gigabytes a day. One caps you at two. One gives you a pool of sixty gigabytes for the month with no daily limit at all. One refuses to name a figure. And one sells an unlimited tier at $48.99 without saying how many days that price covers, which makes it the only product here you cannot compare even in principle.

That is not a semantic quibble for pedants. A comparison ranked by the word “unlimited” ranks nothing, because the plans underneath it differ by a factor of thirty in what they actually deliver. This page decodes each mechanism, works out when each cap bites, and prices the one number Saily leaves out.

Prices below were read on 26 October 2026. Cap figures come from each seller’s own policy or terms page, and where a seller publishes nothing, this page says so rather than guessing.

Which Peru plans are sold as unlimited, and at what price?

Five candidates, four of which publish a daily or monthly figure, and one of which publishes a price with no duration attached.

Four of the five sell a ladder of lengths. Saily sells a single unlimited product and does not say what period the $48.99 covers — not in the plan list, not in the plan details, not in the checkout summary. Its page separately states that plan durations across the catalogue run from five to thirty days, which tells you the universe of possibilities without telling you which one you are buying.

What does unlimited mean at Airalo, Nomad, Ubigi and Holafly?

Four mechanisms, and the difference between them is larger than the difference between any two prices in this market.

Read the third column and the market sorts into three families. Two sellers give you a number per day. One gives you a number per month. Two give you no number at all, and of those two, only one also declines to say how long the plan lasts.

Why the reset hour matters as much as the threshold

A three-gigabyte allowance that resets at 06:40 is a different product from the same allowance resetting at midnight, and the difference is which hours of your day are covered.

Travellers do most of their data work in the evening: uploading photographs, calling home, downloading the next day’s maps. With a rolling reset anchored to an early-morning arrival, the evening sits at the end of the allowance rather than the start of a fresh one, so a heavy night spends tomorrow morning’s speed. With a midnight reset, the evening is the end of a calendar day and the morning is clean.

Neither arrangement is wrong, and only one seller in this market tells you which you are getting.

Where a daily allowance and a monthly pool actually diverge is not the total, and it is the one difference most buyers miss. A daily allowance forgives nothing: a single eight-gigabyte upload on day two costs you the rest of that day at 1 Mbps and then resets, so the trip recovers. A monthly pool forgives the spike but not the total: the same upload comes out of the sixty gigabytes, and nothing throttles you at the time. If your usage is a flat line, the two are equivalent. If it spikes — a backup, a call, a day of tethering — the pool is the kinder structure.

When does a daily cap start to bite in Peru?

Almost never, on a normal trip, which is the finding that makes the whole “unlimited” question less urgent than the marketing implies.

A sightseeing day in Peru runs at about 0.8 GB: maps, a hundred photographs, messages, an hour of social feeds and half an hour of video call. Compare that to the caps on offer:

At 0.8 GB a day you would need to quadruple your usage to touch Nomad’s ceiling, and even then only on the day you did it. The caps exist for the few days that are not normal — the upload day, the video-call day, the day the hotel Wi-Fi fails and the phone carries the evening.

That reframing matters because it changes which cap you should care about. A traveller whose days are all 0.8 GB is not choosing between caps at all; they are choosing between durations and prices, and the cap column is decoration. A traveller with one heavy day a week is choosing between structures, and needs to know whether the design forgives a spike.

Is unlimited the right buy for a four-day trip?

Usually yes, and for a reason that has nothing to do with data: on a short trip the unlimited eSIM is often the cheapest product on the page, not the most expensive.

Four days in Lima, using 1.5 GB a day, is six gigabytes. The metered options at that size are $11.50 for three gigabytes and $17 for five, so a light traveller who wants to buy exactly what they need pays $17 for five gigabytes — more than Nomad’s three-day unlimited at $11, which caps at six gigabytes.

The unlimited eSIM wins here because the metered tiers are priced for people who need the data to last a month, and a four-day trip does not need thirty days of validity. The metered plans that would fit a weekend — a gigabyte or three — are priced per gigabyte at rates that punish small purchases: $4.50 for the first gigabyte against $3.83 for the third.

The lesson inverts at about six days. Beyond that, the metered 10 GB tier at $25 starts undercutting the unlimited plans for anyone whose usage is ordinary, which is why the market-wide comparison puts a metered plan at the top of its ten-day recommendation.

Why is three days of unlimited cheaper than three gigabytes of data?

Because metered tiers are priced for people who need the data to last a month, and a weekend does not.

Look at what $11.50 buys from Nomad: three gigabytes over thirty days. The same $11 buys three days of unlimited at a 2 GB daily ceiling, which is six gigabytes over three days. The metered tier is not more expensive per gigabyte in the abstract — $3.83 against $1.83 — but the traveller on a three-day trip cannot use thirty days of validity, so they are paying for a property they will never touch.

That inversion is specific to short trips and it disappears quickly. At seven days the metered 10 GB tier is the cheaper buy for ordinary use; at four days it favours unlimited. Anyone planning a long weekend should buy the three-day unlimited and stop reading, and anyone planning a fortnight should ignore this section entirely.

Where does Nomad’s 2 GB a day start to cost real data?

At ten days, where its price and Airalo’s are half a dollar apart and the products are not.

Nomad’s ten-day unlimited is $33 and delivers 20 GB at full speed. Airalo’s ten-day is $33.50 and delivers 30 GB. The difference is a third of the usable data for the same money, and it only shows up if your trip uses more than twenty gigabytes — which a normal one does not, and a working one does.

The fourth row is the only one where Nomad’s structure is disqualified rather than merely worse: a video editor will hit 2 GB before lunch and spend the afternoon at 1–2 Mbps. That profile belongs on Ubigi’s pool or Holafly’s uncapped product, and the difference between those two is priced in the Holafly review.

For everybody in rows one and two, the honest summary is that Nomad’s lower cap costs you nothing and its lower price saves you fifty cents, which is not enough to plan a trip around.

Is a pool better than a daily cap for an uneven trip?

Yes, and the trip shape that proves it is the one where the heavy day comes early.

Take a ten-day trip that starts in Cusco with a photography workshop on day two: eight gigabytes uploaded that evening, then ordinary days afterwards. On Airalo’s daily allowance, day two ends at 1 Mbps after the first three gigabytes, the upload takes most of the night, and days three to ten are unaffected because the allowance resets. On Ubigi’s pool, the same eight gigabytes simply come out of the sixty, nothing throttles, and the remaining fifty-two gigabytes last the trip.

The pool wins on that trip and loses on the arithmetic that matters to most people: Ubigi does not sell a ten-day unlimited product at all. Its unlimited options are seven days for $35 (a 20 GB pool) and thirty days for $79 (a 60 GB pool). A ten-day trip therefore has to buy the thirty-day plan, which is 60 GB and $79 against Airalo’s $33.50 — a real difference for a benefit most trips will not use.

Where the pool becomes the obvious purchase is the thirty-day stay, and specifically the thirty-day stay with a laptop. Ubigi allows sharing inside the pool, has no daily reset, and does not care whether your heavy day is Tuesday or Saturday. That combination is not available from any other seller in Peru, and it is the reason a month-long trip with work attached should not be comparing daily caps at all.

What does a rolling 24-hour reset do to a heavy day?

It means your day starts when you landed, not when the clock says midnight, and the difference produces two consequences travellers notice and rarely anticipate.

Activate a profile at 06:40 on arrival and every subsequent allowance begins at 06:40. An evening of uploading that crosses the daily threshold therefore stays throttled until breakfast, which is the hour you want maps for the day ahead. The fix costs nothing and is available before you buy: switch the profile on in the evening — at the hotel, on the first night — so the reset lands while you are asleep and each day’s allowance begins before you do.

The second consequence is that a rolling day does not align with a calendar day, so a trip of ten nights experiences eleven partial allowances rather than ten whole ones. In practice this means the first and last days of the trip share their allowance with a travel day, and the middle of the trip gets the full benefit. On a normal itinerary that is a rounding error; on a trip with two flights in the first three days it is the difference between a comfortable start and a throttled one.

A calendar-day reset behaves differently. One third-party audit of these policies, dated August 2026, records Saily’s reset as midnight in the user’s local time, against a rolling 24 hours at Airalo and Nomad — a distinction neither Saily’s plan page nor its checkout explains. For a traveller who uploads at night, midnight reset is the more forgiving arrangement; for one who uploads at dawn, rolling is.

Is an unlimited eSIM just a metered plan in disguise?

Yes, at every seller that publishes a threshold, and putting the disguise next to the real thing is the fastest way to see what you are buying.

The first row is the one that surprises people. Airalo’s ten-day unlimited gives thirty gigabytes for $33.50, while its own metered 20 GB tier costs $41 for ten gigabytes fewer. The unlimited plan is cheaper than the metered plan with two thirds of the data, from the same seller, on the same page — which is either a pricing error or a deliberate nudge toward the product with the better margin.

Rows three and four show the opposite arrangement. Nomad’s ten-day unlimited is $2 cheaper than its own 20 GB metered tier and lasts ten days instead of thirty, so the metered plan is the better buy for anybody whose trip is shorter than the plan. Ubigi’s 60 GB pool at $79 undercuts two 25 GB plans by $5 while giving ten gigabytes more, which makes the pool the obvious purchase for a month.

Two rows cannot be filled in, and both belong to sellers who declined to publish the number that would fill them.

Which unlimited eSIM gives the longest validity for the money?

At thirty days the ladder flattens into four products within $3 of each other, and the differences that decide it are structural rather than financial.

Airalo and Ubigi charge the same $79 for the month and deliver opposite structures. Airalo gives ninety gigabytes, thirty per day, on a hard ceiling. Ubigi gives sixty gigabytes in a pool with no daily limit. Per gigabyte Airalo is cheaper; per heavy day Ubigi is more forgiving; and for anyone tethering a laptop Ubigi is the only one of the two that will not throttle the laptop at three gigabytes.

Holafly’s $81.90 sits $2.90 above both and offers the one thing neither does: no published ceiling at all. That is a strange thing to pay $2.90 for unless you have a reason to distrust a number, and anyone who does should read the Holafly review’s arithmetic before deciding.

Saily’s row is the interesting one, and it is the only row in this table with two blanks. At $48.99 for thirty days it is the cheapest month in the market by $30; at $48.99 for anything shorter than fifteen days it is not competitive at all. Both statements come from the same price tag.

What three questions decide any unlimited purchase here?

Three, in this order, and they take about a minute each once the plan page is open.

What is the threshold, and does the seller print it? If the answer is a daily figure, multiply it by the days and compare that number to your trip’s usage. If the answer is nothing, you are buying an unquantified product and should ask what happens when it runs out. Two of the five sellers in this market print nothing.

What happens at the threshold, and for how long? A defined ceiling with an undefined penalty (Airalo: 1 Mbps until reset) and an undefined ceiling with a defined penalty (Holafly: reduced for up to a day) are different products, and which is better depends on whether you fear running out or fear being slowed at the wrong moment.

How long is the plan, exactly? Not the length you think you need — the length printed on the plan you are buying. Saily’s unlimited tier fails this question outright, and every other seller here passes it.

Anyone who answers those three and then buys on price will make a good decision in this market. Anyone who buys on the word unlimited is choosing among products that differ by a factor of thirty in usable data without knowing which one they got.

Why does Saily Peru sell unlimited without a duration?

That is the question the page does not answer, and the honest response is that the omission is worth more than the price difference between the plans.

Saily’s Peru page lists Unlimited GB — US$48.99 at the top of the plan list, above 1 GB, 3 GB, 5 GB, 10 GB and 20 GB. Every other row carries a validity: 7 days for the 1 GB, 30 days for the rest. The unlimited row carries none. Its general product description says plan durations run from five to thirty days, which is a range rather than an answer.

Third-party trackers that have tried to record the figure disagree with each other and with Saily, which is the same pattern the Argentine unlimited tier showed at €51.49. Two consecutive countries, the same missing number, which suggests a product decision rather than a page that has not been updated.

What the missing number is worth in dollars

Sixty dollars, if you compare the two ends of the table below. The same product is the cheapest month in the Peruvian market and the most expensive week, and the difference is not a discount or a promotion — it is a single figure the page does not publish.

The reason it matters is that the same $48.99 is the worst unlimited eSIM in Peru or the best, depending entirely on the number nobody printed:

One price, and a verdict that flips from “avoid” to “the best value in the market” as the duration moves from a week to a month. No other product on this page has that property, and no other product on this page asks you to buy without knowing which end of that table you are in.

So is Saily’s unlimited worth $48.99?

Only if you can find out the duration before paying, and only if the answer is fifteen days or more.

The test is mechanical. Add the plan to the basket, go to the checkout screen, and look for the days. If the checkout states thirty, the purchase is straightforwardly good: $1.63 a day for an uncapped phone connection beats every other unlimited plan in Peru, including Airalo’s $79 month and Holafly’s $81.90.

If the checkout states seven or ten, close the tab and buy the Airalo tier instead, because at those lengths Saily is charging a premium for a product with an unpublished ceiling.

There is a second reason to think twice at the shorter end, and it has nothing to do with the price. Saily does not name a Peruvian network — its page says only that you get “Peru’s best networks”, a sentence that cannot be checked and cannot be compared. Airalo names Movistar, Holafly names Movistar and Claro, Ubigi names Movistar, Nomad names two. Saily names none. On a route that stays in the cities that omission costs you nothing; on a route that leaves them it means you find out which network you bought after you arrive.

What does Saily’s metered line look like beside the others?

Weak at every size, which is worth stating because the unlimited tier is not the only product that page sells.

Saily wins exactly one row, the three-gigabyte tier, by fifty-one cents. At 10 GB and 20 GB it is six dollars behind, which is the largest gap in the Peruvian metered market at those sizes.

What Saily sells that the others do not is three things, and they are all in the terms rather than the price list: a 180-day window between buying and activating, no restrictions on hotspot, and an optional US phone number with calls and texts attached. For a trip booked months ahead, or for anyone who needs to receive a bank verification code, those are the reasons to buy from this seller at all — not the data.

What does Saily include that costs extra elsewhere?

Four things, none of which is data, and three of which are useful on a long trip.

A 180-day activation window. Buy in January for a June flight and the plan is still live, which is the longest window in this market and the reason Saily’s metered tiers sell to people who book early. Nomad’s 60 days will activate itself in the meantime; Saily’s will not.

No hotspot clause. Its page states no sharing restrictions at all, against Holafly’s 1 GB a day and a shared allowance at Airalo and Nomad. For a family or a laptop user this is the single most valuable thing Saily sells, and it costs nothing extra.

An optional US phone number. Calls and texts on a separate plan, which makes Saily the only seller here that can receive a bank verification code or call an airline. Everyone else is data-only.

Three per cent back in Saily credits on each purchase, plus the app’s ad-blocking and virtual-location features. The credits are worth about $1.47 on a $48.99 plan, which is a rounding error rather than a reason to buy.

What Saily sells is terms, not tariffs. Its data is the most expensive per gigabyte in the metered market at 10 GB and 20 GB, and its unlimited tier is unpriceable without the duration — but if you need a plan that survives a five-month booking lead time, shares without a clause, and can receive a text message, it is the only one that does all three.

What can you do when the allowance runs out and you still need speed?

Three options, in ascending order of cost, and only one of them is usually right.

Wait. The reset is never more than a day away, and a throttled connection still carries maps, messages and audio. For anything that can wait until tomorrow, waiting costs nothing and is the correct answer most of the time.

Move the load to Wi-Fi. The hotel, the café, the restaurant with the password on the wall. This is what the allowance is designed to push you toward, and on a trip with reliable accommodation it removes the problem entirely.

Buy a top-up or a second profile. A top-up attaches to the live eSIM at Airalo and Nomad and activates when the current plan expires, which solves an expiring plan but not a throttled one — for a same-day throttle, the only real fix is a second profile from another seller, installed and switched on for the rest of the day. That costs $4.50 to $11 and is worth it exactly once per trip, on the day you have something to upload.

The one thing not worth doing is upgrading mid-trip to a bigger unlimited eSIM. The new plan starts its own clock from activation and does not merge with the old one, so you pay full price for a second duration and keep the throttle you were trying to escape.

Which of the five should you buy for your trip?

Eight rows cover the realistic cases, and the answer changes with the length rather than with the brand.

Two rows are conditional and both deserve flagging. Saily’s thirty-day case is only true if the checkout confirms thirty days; if it does not, Airalo’s $79 month is the honest answer. And Holafly’s ten-day row is only for people who will exceed thirty gigabytes, which most ten-day trips do not — the market-wide comparison has the usage arithmetic behind that claim.

Where the definitions still leave people guessing

Is any Peru eSIM genuinely unlimited? None of them is unlimited in the sense of guaranteed full speed at all times. Four sellers publish a threshold and throttle above it; one publishes no threshold and reserves the right to reduce speed for up to a day. The data never switches off, which is the honest meaning of the word in this market.

Does the daily allowance reset at midnight or 24 hours after activation? At Airalo and Nomad it is 24 hours from activation, rolling. At Ubigi there is no daily reset at all. A third-party audit of the policies dated August 2026 records Saily’s reset as midnight local time, and Saily’s own pages do not state it — which is another reason to read the checkout before buying.

Can I use a Peru unlimited plan as a hotspot? Airalo allows it with no device limit, counting against the daily allowance. Nomad supports it inside its 2 GB. Ubigi allows it inside the pool. Holafly allows 1 GB a day. Saily states no restrictions, which makes it the only seller here with no sharing clause at all.

What happens when the allowance runs out? Speed drops and the connection continues. Nothing switches off, nothing charges you extra, and the next reset restores full speed. Nobody in this market bills overage.

Will the unlimited plan work outside Peru? No. A Peru-only profile stops at the frontier regardless of how much data is left on it, and that includes the long validity on a thirty-day plan. A trip that crosses into Bolivia or Chile needs regional coverage rather than a bigger Peru plan.

Should I test any of this before buying? A free trial profile settles the compatibility question for nothing, and the supported device list settles it before that. If a plan will not connect on landing, the activation error catalogue sorts the causes, and the carrier guide covers what the networks themselves do.

Is a longer unlimited eSIM ever worse than a shorter one? Yes, in one specific way: a thirty-day plan bought for a ten-day trip charges you for twenty days of validity you cannot use, and the per-day rate that made it look cheap is only available to people who stay. Buy the length you need unless the step up is under $4.

Do these plans work on 5G in Peru? Where the underlying network offers it, and all four Peruvian operators bought 3.5 GHz spectrum in the 2023 auction. Whether your handset gets 5G depends on the band support and the network you are riding, not on the plan tier.

What if I need unlimited data for two phones? One eSIM installs on one handset. Two phones need two plans, or one plan shared over a hotspot — which works at Airalo and Ubigi, is capped at 1 GB a day at Holafly, and is unrestricted at Saily.

The short version, for anyone who skipped the tables

“Unlimited” in Peru is a daily allowance at Airalo and Nomad, a monthly pool at Ubigi, an unpublished arrangement at Holafly, and an unpriced duration at Saily. Only one of those five is vague about both the amount and the period, and it is the only one whose value cannot be established before checkout.

Buy on the structure, not the word. If your days are ordinary, the cheapest daily allowance wins and the cap is decoration. If you have one heavy day a week, buy the pool. If you have a laptop, buy the pool or nothing. And if you are buying a month from Saily, confirm the duration first — the same $48.99 is the best and worst unlimited purchase in Peru depending on a number the page does not print.

Roami’s Peru plans print the duration next to the price on every card, which is the minimum this page has been asking of the other four and one that two of them still fail.
