Best eSIM for Peru: What Eight Gigabytes Actually Costs

Search for a Peru eSIM and the first thing you meet is a wall of plans labelled unlimited, priced from about $11 to about $82, and ranked in an order that has nothing to do with what a trip actually uses. Rank the same plans by the gigabytes a normal visitor burns in ten days and the order flips: the product at the top of most lists, thirty days of unlimited at $79, is the one almost nobody needs, while the plan that wins costs $17 and appears in almost no comparison.

That gap is not a trick of the market. It exists because “unlimited” is the only word in this category that is cheap to print and expensive to check, and because nobody selling a $79 plan has an incentive to publish a table of how much data a week in Cusco really consumes. This page does both: it prices every Peru plan that is actually on sale to a US buyer, and it counts the gigabytes first.

The answer in three lines. A ten-day trip of ordinary sightseeing uses six to eight gigabytes, and the cheapest eSIM that covers it is Ubigi’s 10 GB at $24. A ten-day trip with daily photo backups and video calls uses fifteen to twenty, and the cheapest cover is $33.50. A month of remote work from Cusco needs twenty-five gigabytes or more, and at that point the arithmetic finally points at a large plan — which is not the same thing as an unlimited one.

Everything below is the working behind those three sentences. Prices were read off each seller’s Peru page on 26 October 2026, in US dollars. Cap figures come from each provider’s own fair-use page or terms, not from a comparison site.

How much data does a ten-day Peru trip use?

Start here, because every plan decision downstream depends on a number almost nobody measures. Tourists overestimate this badly, and the overestimate is what sells a $79 plan to somebody whose phone will show 7 GB used at the end of the fortnight.

Break a normal day into its parts:

Ten days at that rate is eight gigabytes. Add a cloud backup of five hundred photos and you are at nine and a half. Add an hour of video every evening because the hotel television is in Spanish and your series is not, and you land near thirteen. The eSIMs that sell for $79 are sized for a person who does all of that every day for a month, and almost nobody does.

The exception is real and worth pricing properly. If you shoot video for a living, back it up nightly over mobile data, and take two video calls a day, the ceiling moves to roughly 2.5 GB a day — 25 GB for ten days. That is the profile that should be shopping in the unlimited aisle, and it is a minority of travellers, not the default one.

One more correction to the mental model: the day you land and the day you fly out are not full days, but they are the two days when you use the most data in the shortest time. Maps, a ride, a translation app, a photo of your passport sent to somebody who needs it. Budget 1 GB for arrival day regardless of how disciplined the rest of the trip is.

Why do the comparison pages say fifteen gigabytes for ten days?

Because they count the way a plan seller would count, not the way a phone behaves. The number that circulates in this market is about 1.5 GB a day for a “moderate” traveller, which turns a ten-day trip into fifteen gigabytes and a recommendation in the $40 to $47 bracket. The line items above do not support it.

The difference is entirely in three activities, and all three are optional:

• Backing up the camera roll nightly over mobile data. A mirrorless camera shooting 150 frames a day, sent up at full size, is about 1.2 GB a night, or 12 GB across ten days if you do it every night. Most people back up on hotel Wi-Fi, or not at all until they get home.
• Streaming video instead of watching the hotel television. An hour of 480p is about 700 MB, so ten evenings is 7 GB, the single largest addition most people make.
• Tethering a laptop. A browser session is light; a system update is not.

Take all three out and the trip lands at the eight gigabytes this page prices. Add the evenings of video and you are at fifteen, which is exactly the number the comparison pages quote. Add the camera roll as well and you are past twenty. The reason it matters is not the arithmetic for its own sake: it is the difference between a $24 plan and a $46 one, and none of the pages that quote 1.5 GB a day show you which three habits they assumed.

The honest rule is to count your own evenings. If the phone is the television, buy at 1.5 GB a day and ignore the table above. If the hotel has a screen and a password, buy at 0.8 and spend the difference on the trip.

What do five gigabytes buy once you are in Peru?

Gigabytes stay an abstraction until you translate them into the things you do on the trip, and the translation is what stops people overbuying. Every figure below is consumption measured at the app, not an allowance a seller chose:

The arithmetic is uncomfortable for anyone selling a large plan: five gigabytes covers a light ten-day trip, eight covers an ordinary one, and a heavy one starts at ten. The categories where people run out are narrow and predictable — uploading video, backing up a camera roll nightly, tethering a laptop, or leaving a hotspot running for a car full of passengers.

Who needs unlimited data in Peru, and who does not?

One group, and naming it makes the rest of this page easier to read. If you are travelling with children and running a hotspot so two tablets can play downloaded films, your consumption is not your own and it is not small: two hours of streamed video per child per evening lands near 1 GB a night before anybody’s maps are counted. That is a real reason to buy unlimited, and it is a different reason from the one the price lists imply. Two adults with two phones and no laptop are not that group.

Which Peru eSIM is cheapest at 3 GB, 10 GB and 20 GB?

Four sellers dominate this market and the winner changes at every tier. That is the single most useful fact on this page, because it means “which provider is cheapest in Peru” has no answer — only “cheapest at the size I need” does.

Read the bold cells down the page: Nomad, Saily, Nomad, Ubigi, Nomad, Ubigi. Four different sellers hold the cheapest position at some point in the ladder, and no single brand is the answer across the range.

Two details in that table cost people money.

The first is the validity column, not the price column. Nomad’s $4.50 entry plan lasts seven days; Airalo’s $4.50 entry plan lasts three. Same dollar figure, less than half the useful life. A four-day Lima trip on Airalo’s entry tier is already expired when you land, while the same money on Nomad’s runs to the end of the week. Airalo’s own fixed-data tiers start at three days, and that is a product decision rather than an error, but it is invisible unless you read the right-hand column.

The second is that 20 GB is where the market stops competing. Only three of the four sellers have a 20 GB tier at all, and the spread between them is $6. Above that, Ubigi is alone at 25 GB for $42. If your trip needs twenty-five gigabytes, you have one metered option and a couple of unlimited ones, and the comparison becomes a different article.

Per-gigabyte, the whole table lands between $4.50 and $1.68. The $1.68 is Ubigi’s 25 GB tier, which is a bad deal to buy deliberately: nobody with a two-week holiday needs 25 GB, and the per-gigabyte rate is only available to people willing to pay for three times what they use. Cheapest-per-gigabyte is a way to feel clever while overbuying.

Is unlimited cheaper than metered data in Peru?

Yes, at almost every length — and the margin is much wider than the price tags suggest. This is the finding that makes the Peru market unusual, and it needs the fair-use caps decoded before it makes sense.

Take Airalo. Its Peru unlimited line runs 3, 5, 7, 10, 15 and 30 days at $16.00, $19.00, $27.00, $33.50, $44.00 and $79.00. Now apply its published cap: the default daily high-speed allowance is 3 GB, after which speed drops to 1 Mbps until the next 24-hour reset from activation. Multiply the cap by the days and you have a hard number of usable gigabytes:

The bottom row is the punchline. Ninety gigabytes of usable data for $79 is 88 cents a gigabyte, which undercuts every metered plan on the market — including Ubigi’s $1.68 and Nomad’s $1.75 — by roughly half. Nobody frames it that way, because “unlimited” and “cheapest per gigabyte” do not look like they belong in the same sentence, and because the plan is three times bigger than most trips need.

The same exercise on Nomad produces a different number, and the difference is the whole competitive story of this market.

What does unlimited mean at Nomad, Ubigi and Holafly?

Three sellers, three different products behind one word, and only one of them is actually uncapped. This is where a Peru comparison earns its keep, because the eSIMs that look interchangeable are not.

Nomad caps at 2 GB a day. Its unlimited line is 3, 5, 7 and 10 days at $11, $18, $25 and $33. At two gigabytes a day, ten days is twenty gigabytes usable for $33 — $1.65 a gigabyte against Airalo’s $1.12 for the same money. Nomad’s headline is half a dollar cheaper and its product delivers a third less.

Ubigi sells a pool, not a daily allowance. Its 30-day unlimited is $79 for 60 GB at full speed, then 2 Mbps for the rest of the validity, with no daily reset at all. Its 7-day unlimited is $35 for a 20 GB pool. This is a different bargain from Airalo’s: a single heavy day cannot exhaust it, so an 8 GB upload on day two leaves nineteen days of full-speed data intact. For a photographer or a video editor, that tolerance is worth more than the 30 GB headline difference suggests.

Holafly publishes no number at all. Six lengths, all unlimited, $16.50 to $81.90, and the fair-use page says only that a slowdown may last “no more than one day” and resets afterwards. Treating it as a quantified allowance is impossible, which is the point of the separate Holafly review — the value of that plan depends entirely on which trip length you buy it at.

Set the caps side by side and the market sorts itself:

Two of those five rows cannot be compared at all, and no ranking page says so. The full breakdown of what each seller means by unlimited goes further into the wording; the short version is that only Holafly sells something it will not put a number on, and only Ubigi sells a pool big enough that the cap almost never arrives.

Which seller lets you share the connection with a laptop or a partner?

Sharing is the quietest difference between these plans and the one most likely to matter on a family trip or a working one. Every seller allows tethering; what they allow is not the same thing as what they permit at speed.

The Holafly line is the one to read twice, because “unlimited” and “one gigabyte a day of hotspot” sit in the same product. Anyone planning to work from a laptop for a week should treat that plan as a 7 GB plan for the laptop and an unlimited plan for the phone, and price it accordingly.

One plan with a hotspot, or two plans?

For a couple, the instinct is to buy one plan and share it, which costs half as much and works until the two of you separate for the afternoon — one to a museum, one to a market — and the phone with the plan goes with one of you. Two Nomad 5 GB plans cost $34 and remove the coordination problem entirely. For a family of four the sum flips: four plans cost more than one, and the hotspot is already how the tablets are being fed.

The honest rule is that sharing suits people who spend the day together and fails for people who split up. A two-week trip where every afternoon is separate is two plans, not one.

Which plan is cheapest per day at 7, 10 and 15 days?

Cost per day is a different measurement from cost per gigabyte, and the two do not agree — which is the reason two careful buyers can reach opposite conclusions from the same price list.

Per day, Nomad wins at seven and ten days. Per usable gigabyte, Airalo wins at every length — $1.29 against $1.79 at a week, $1.12 against $1.65 at ten days. Both statements are true, and the one that applies to you depends on whether your constraint is money or data. A traveller who uses 4 GB in a week is buying time and should take Nomad. A traveller who uses 15 GB in the same week is buying data and should take Airalo at $2 more.

Ubigi’s 30-day plan is in the fifteen-day row for a reason: at $79 it is the cheapest per day of anything in this market, but only if the trip is long enough to use a thirty-day plan. Buying it for a fortnight means paying for sixteen days you will never see.

Why is Airalo’s five-day plan cheaper per day than its seven-day?

Because its ladder was built by adding durations over time rather than by fitting a price curve, and the seam is visible if you look at what each extra day costs.

Moving from three days to five costs $3, which is $1.50 per extra day. Moving from five days to seven costs $8, which is $4.00 per extra day. Moving from seven to ten costs $6.50 for three days, or $2.17 each. The seven-day plan is the one tier in Airalo’s own ladder where the marginal day is priced nearly three times higher than the day before it.

The instruction that follows is odd but unambiguous: if your trip is six days, do not buy the seven-day Airalo plan at $27. Buy the ten-day at $33.50 and get three spare days for $6.50, or buy Nomad’s five-day unlimited at $18 and accept the tighter cap. The seven-day tier is the only place in this market where paying more buys you a worse rate than the tier beneath it.

How many days are you buying for, once you count the flight?

Almost every wrong purchase in this market is a day-count error rather than a brand error, and the error has one cause: people count the days they will be doing things, and plans are sold in days that include the two where you are in transit.

A seven-night trip is an eight-day purchase. That single line turns Airalo’s seven-day plan from the obvious choice into a plan that expires on the way to the airport, and it is why the tier above the one you think you need is usually the right one.

Count nights, then add one

The rule holds because of how the two ends work. You land, switch the profile on, and the clock starts — usually on first connection to a local network. You fly out on the last morning, and the profile is still running until you leave the country. A ten-night booking therefore needs eleven days of coverage, and a seven-night booking needs eight.

The two exceptions are worth knowing. If you land late at night and leave early in the morning at the other end, the arrival and departure days consume almost nothing, and a tier that is one day short will usually survive on the day you leave as long as you are at the airport and on Wi-Fi. If you land in the morning and leave in the evening, the opposite applies and the shortfall is real. Both exceptions favour counting properly rather than buying the biggest plan to be safe.

What are you paying for when local data costs $0.45 a gigabyte?

Peru is one of the cheapest mobile markets on earth: Cable.co.uk’s survey puts a gigabyte at about $0.45, 40th of 237 countries. So a ten-day trip using eight gigabytes is about $3.60 of data at the national average rate. The travel eSIM that covers the same trip costs $24 to $33.50.

That gap is real and it is not a scandal, but it is routinely mis-stated by both sides. The eSIM is not selling you data at a markup; it is selling you the absence of an errand. The local alternative means biometric registration at a carrier store, in person, since OSIPTEL’s rules changed at the end of 2025 — the carrier guide walks through exactly what that involves — plus a taxi, plus a queue, plus a line that deactivates itself if it sees no traffic for a few idle days.

Price the errand honestly and the comparison usually lands where this one does. On a four-day trip, the fixed cost of getting to a shop exceeds the entire saving. On a month in one city, the local option wins on money by a wide margin and the question becomes whether you value two hours of your first morning more than $20. What no arithmetic supports is the middle case: buying a local chip for a ten-day trip that moves between four cities, where you pay the errand three times in taxis and lose the coverage guarantees you had at home.

Which plan fits a three-day Lima stopover?

Lima for a long weekend is the shortest trip this market serves, and it is also where the most money is wasted, because the same instinct that says “buy the biggest” meets a ladder whose first two rungs are badly priced.

The answer is Nomad’s 3-day unlimited at $11. Five dollars cheaper than Airalo’s three-day at $16, and six gigabytes of usable data for a trip where you will mostly be in Miraflores with hotel Wi-Fi. Holafly’s three-day is $16.50 for a product with no published cap; it is the right buy only if you have a reason to distrust a 2 GB day, and three days in Lima is not that reason.

If you intend to work from a café for one of those days, add a tier: Nomad’s 10 GB metered at $25 outlasts the trip and costs less than Airalo’s ten-day unlimited. If you are connecting through Lima on the way to Cusco and only need the airport and a ride, the cheapest defensible purchase is the 1 GB tier at $4.50 and a hotel Wi-Fi password.

Lima’s metro covers a fraction of the city, which is worth knowing for a different reason: ride-hailing is the default here, and ride-hailing is the one app that fails badly without data. Budget the arrival hour accordingly.

Which plan covers Lima, Cusco and the Sacred Valley in ten days?

This is the standard first trip: two nights in Lima, a flight to Cusco, four nights working through the Sacred Valley, a night in Aguas Calientes for Machu Picchu, and back. Ten days, four beds, and about eight gigabytes of ordinary use.

At that size the metered market wins. Ubigi’s 10 GB for $24 covers the whole trip with room, and its 30-day validity survives a delayed flight home. Nomad’s 10 GB is a dollar more at $25 and names Claro alongside Movistar, which is the dollar to spend if your route leaves the Movistar footprint — Cusco and the Sacred Valley do not. Either one is $8.50 to $9.50 cheaper than Airalo’s ten-day unlimited at $33.50.

The case for paying the extra $9.50 is specific rather than general: you are buying the right not to count. On this itinerary the counting is not onerous — the Sacred Valley days are driving days with map use and little else, and Cusco’s hotels have reliable Wi-Fi. What you would be buying with the unlimited plan is insurance against one bad day, and a 10 GB allowance against eight gigabytes of use already is that insurance.

Where the calculation changes is the train. The journey to Aguas Calientes runs through valleys where signal comes and goes, and the two hours before departure are when you want a working phone to confirm the booking, the bus and the weather. Download the ticket to the phone rather than trusting the app to load it at Ollantaytambo station. That costs nothing and removes the one moment on this route where a data plan is load-bearing.

What changes on a two-week trip that adds Arequipa and Puno?

Two weeks adds roughly four gigabytes of ordinary use, brings the total to about twelve, and pushes you into a bracket where the metered table has three near-identical options — Nomad 20 GB at $35, Ubigi 25 GB at $42, and Airalo’s ten-day unlimited at $33.50 if the trip fits inside ten days.

The itinerary matters more than the price here, because Puno and Lake Titicaca sit at 3,800 metres and the days are shorter than the plan assumes. Altitude makes people go to bed early, which reduces evening data use, and it makes the phone itself slower to lock onto a network, which increases the time spent staring at a spinner. Neither effect is large enough to change a tier decision on its own.

What does change the decision is the border. A Peru-only plan stops at the frontier, and a fortnight that reaches Titicaca often continues to Copacabana or La Paz — the Bolivia carrier guide covers what happens on the other side, and the regional South America options exist for exactly this shape of trip. Buying a Peru-only plan and then a second plan at a border town is the most expensive way to solve it.

For a fortnight that stays inside Peru, the honest ranking is: Ubigi’s 25 GB at $42 if you want one purchase and no thinking, Nomad’s 20 GB at $35 if you want the lowest bill, and Airalo’s 15-day unlimited at $44 if you would rather not count at all and want the 3 GB daily tolerance in reserve. All three are within $9 of each other. The difference between them is smaller than the difference between any of them and buying two plans in a panic.

Which plan works for a month in Cusco on a laptop?

A month changes the problem from gigabytes to architecture, because a laptop tethered to a phone is the one use case where every “unlimited” plan in this market fails visibly.

Holafly’s hotspot allowance is 1 GB a day, and its own documentation describes a seven-day plan as including seven gigabytes of shareable data in total. That is a fine number for sending a few files and a poor one for a working week. Airalo allows tethering without a separate limit but counts it against the same 3 GB daily allowance, so a video call from the laptop plus an afternoon of syncing will hit the cap by mid-afternoon. Ubigi permits sharing and has no daily reset, which makes its 60 GB pool for $79 the only plan here that behaves like a data allowance rather than a ration.

Set against that, the local option gets serious for the first time. A month is long enough to amortise the registration errand, long enough that a deactivated prepaid line can be revived, and long enough that the per-gigabyte difference between $0.45 and $0.88 stops being trivia. If you are staying a month in one city and your work depends on the connection, the right answer is a local line plus a travel eSIM as the backup that works on day one while you sort the paperwork out.

Two practical notes that only matter at this length. Nomad’s plans activate automatically 60 days after purchase if you never connect them, which is a trap for anyone buying early for a long stay. And Saily’s unlimited tier at $48.99 does not state its duration on the Peru page, so its value over thirty days is unknowable before checkout — a point developed in the unlimited-plan breakdown.

How do you avoid buying the wrong tier twice?

The most common expensive mistake in this market is not picking the wrong seller. It is buying a second plan mid-trip because the first one ran out at the wrong moment, and paying full price for a product you only needed for two days of it.

Three habits prevent almost all of it.

Buy for the days between wheels down and wheels up, not the days you are travelling. A ten-day itinerary usually contains eleven or twelve days on the ground once you count the overnight flights. Airalo’s ten-day plan is a deadline, and the deadline falls on the morning of the day you fly home, which is the day you most need a map.

Check whether a top-up attaches to the same profile. Airalo and Nomad both sell add-ons that activate when the current plan expires, which means no second QR code and no risk of two profiles fighting over the data line. A top-up is worse value per gigabyte than a fresh eSIM and much better value than a second one bought in a hurry at an airport.

If you are unsure between two tiers, buy the smaller one. The step up costs $6 to $8 in this market and can be taken at any point; the step down is not refundable. A 10 GB plan at $25 plus an emergency top-up beats a 20 GB plan at $35 you never fill.

Should you buy the Peru eSIM now or the week before you fly?

Buying early feels prudent and is occasionally the worst thing you can do, because several of these plans start a clock the moment they are bought rather than the moment they are used.

Nomad’s 60 days is the number that catches people, because sixty days sounds like plenty until a trip is booked in spring for late summer. Buy a Nomad eSIM in April for an August departure and it activates itself in June, while you are at work, and by the time you land the allowance is half gone. Saily’s 180 days survives the same mistake; Ubigi’s model does not start until you connect.

The rule that avoids the problem entirely

Buy in the week before departure unless the seller publishes a window longer than the gap between purchase and flight. There is no price advantage to buying months early — none of these five sellers runs a meaningful early-booking discount — so the only thing buying early buys you is the chance to install the profile on home Wi-Fi rather than airport Wi-Fi. A week is enough for that, and it leaves the install on home Wi-Fi where it belongs rather than on an airport captive portal that wants a room number.

Six questions that decide whether the plan works

Will it work the moment I land in Lima? Most Peru profiles activate on first connection to a local network, so installing at home and switching the line on after landing is the sequence that works. Check your handset against the compatibility list before you buy, not after.

Do I need a local phone number? Not for a normal trip. WhatsApp handles everything a tourist needs, and hotels, guides and drivers all use it. Saily is the one seller here that will add a US number for calls and texts, which is useful if you are expecting delivery calls rather than restaurant bookings.

Which network will I be on? Airalo names Movistar, Nomad names Movistar and Claro — with at least one of its own product pages naming Entel instead — Ubigi names Movistar, Holafly names Movistar and Claro, and Saily names nobody. Claro is the fastest network in the country on Ookla’s measurements, so a seller that names it is offering you something the others are not. Whether that matters for your route is a coverage question, and the coverage picture sits in the carrier guide. Two hardware notes sit underneath the network question: 5G appears only where the operator has it and your handset carries the band, and an eSIM installs against the handset’s EID rather than its IMEI, which is why the compatibility checker asks for one and not the other.

Is there a cheaper way to test the whole thing? Yes: a free trial profile with a small allowance costs nothing and answers the compatibility question in five minutes.

What if the plan expires early? A top-up, not a second plan. Airalo and Nomad both attach add-ons to the live profile; a fresh plan means a second installation and a second deadline.

Can I move the profile to a new phone mid-trip? Usually not. Most travel profiles install once and are tied to the handset they were first activated on, and some sellers say so explicitly. If you are travelling with a spare phone and intend to switch, settle the question before you buy rather than after the old one goes for a swim.

So which Peru eSIM should you buy?

Five purchases cover almost every trip, and none of them is the $79 plan that tops the ranked lists.

Read that table down the column and the cheapest adequate plan wins four times out of five; the fifth is the case where you are buying capacity rather than data. That is the opposite of how this market is usually sold, and it follows directly from the first section of this page: eight gigabytes is a normal ten-day trip, not a light one.

Roami’s Peru plans run on the same tier logic this page has just laid out, so every calculation above transfers to them without adjustment; the logo on the receipt is the least interesting variable in the decision. Read one of the brand pages first if Airalo or Holafly is already in your shortlist, because both of them have a single structural quirk that decides more than the price does.
