The Best eSIM for Chile Depends on Which Network You Get

Most lists of the best eSIM for Chile sort by dollars per gigabyte and produce a winner nobody should buy. The cheapest plan is usually the one riding the network with the thinnest rural footprint, and Chile is a country where the roads between the interesting places run through valleys with one cell site each.

So this page sorts differently. It starts with the network underneath each brand, because that is the variable a traveller cannot change after purchase, then moves to the shape of the allowance, then to the sharing rule, and only then to price. The order is not arbitrary: get the first one wrong and the other three are arguments about the wrong product.

Four brands have verifiable Chile pricing this month: Airalo, Nomad, Saily and Jetpac, plus this site’s own plans. A fifth, Holafly, sells only unlimited here and is covered separately because it is a different instrument rather than a different price. If you have not decided whether to buy a travel plan at all, the Chile eSIM guide works through that question first.

Three Trips, Three Different Winners

Almost every visitor to Chile is on one of three itineraries, and they do not want the same product.

The Santiago city break. Four or five nights, a day trip to Valparaíso, no car. Data need is under five gigabytes. Every network is fast in Providencia, so coverage is irrelevant and the decision is price plus installation friction.

The two-week drive. Santiago, the coast, a wine valley, then south through the lake district. Ten to twenty gigabytes for one person, more with two sharing. Coverage matters a great deal, because the failure mode is a highway with no signal rather than a slow page.

The long stay or the working trip. A month, a rental with a desk, video calls and uploads. Forty gigabytes and up, or a local prepaid line with a thirty-day bundle. Here the validity structure and the throttle policy dominate, because you are buying something closer to a home connection.

There is a fourth case that the market serves badly and that gets its own page: Chile plus Argentina, where no carrier in either country sells a dual-country tourist product and the choice is a regional plan or two purchases.

What the Best eSIM for Chile Cannot Fix

The phrase is asked as though a winner exists that closes every gap at once, and it is worth saying plainly which gaps stay open no matter what you buy.

It will not give you a Chilean number. Saily’s messaging add-on is the closest thing for sale in this category and it still is not a +56 line that a bank, a delivery app or a landlord will verify against. Every system in the country that asks for a number to confirm something is asking for a number tied to a person, and a travel profile is not that.

It will not unlock a carrier-locked handset. A phone bought on an instalment plan in some markets is locked to the network that sold it, and an eSIM is a SIM as far as that lock is concerned. This is the single most common wasted purchase in the category and it is checked in ten seconds before paying, not after landing.

It will not make a weak network behave. Coverage on the road between towns is a property of the towers, and no plan marketed as premium buys access to towers that were never built. The most expensive product here and the cheapest are both invisible in a valley with one site.

It will not follow you onto a second device you did not plan for. One profile covers one handset. A tablet, a second phone or a work laptop that needs its own connection is a second purchase, and the hotspot rule is what stands between you and that.

It will not replace the four minutes of setup. The profile has to be installed, the line has to be selected for data, and roaming has to be enabled on that line specifically. Nothing in the purchase does any of that for you, and a plan that is installed but not selected looks exactly like a broken plan.

What remains after that list is still the decision most people actually face: given a fixed itinerary, which of these products behaves best on it. That is a narrower question, and it has a real answer.

Who Owns the Towers Under Each Brand?

This is the single most useful column in any comparison of this market, and it is the one most pages leave blank.

Chile has four networks. Entel has the deepest rural reach and the best reputation on the main highway south. Movistar is strong in cities and is the wholesale partner behind Airalo’s Chile product. Claro has the widest retail presence and is what Jetpac uses. WOM is the cheap fourth network with the thinnest coverage outside urban areas.

Two plans can cost within a dollar of each other and behave completely differently on a road forty minutes outside a town, because one rides Entel and one rides the cheaper wholesale deal. That is not a marginal difference in a country this shape.

The second variable is fallback. A plan that rides one network stops when that network has no signal; a plan that can attach to any available partner keeps working through small towns where the first network has nothing. Multi-network profiles are worth a few dollars more on a driving trip and worth nothing on a city break.

A provider that names its network has done the work. One that writes “top local networks” has told you something about how much it tested.

Airalo Rides Movistar, and That Is the Review

Airalo is the largest marketplace in the category, and its Chile product is a competent, unremarkable mid-market plan on a network that is good in cities.

The pricing ladder is short: a gigabyte over a week near five dollars, two gigabytes over a fortnight near eight, five gigabytes over a month near fifteen and a half, twenty gigabytes over a month near forty-eight. There is also an unlimited line priced by the day, from around twelve and a half dollars for three days up to north of ninety for a month.

The per-gigabyte rate at the top of the fixed ladder is under two and a half dollars, which is ordinary rather than competitive. The unlimited line is the weaker part of the product: per-day pricing compounds, and a three-week trip at the daily rate costs more than a forty-gigabyte fixed plan for a traveller who would have used fifteen.

Where Airalo earns its place is breadth. The catalogue covers most of the planet, which makes it the sensible anchor for a multi-country trip, and the app is the best in the category for installing and topping up. Its Chile product page is the authoritative source for the current network partner, because wholesale agreements get renegotiated and a review written in one quarter can be stale in the next.

Where it is weak: Movistar’s rural footprint is thinner than Entel’s, so a driving trip south is the case where this plan underperforms its price. For a Santiago-and-coast itinerary that never matters.

Nomad’s Twenty Gigabytes for $39 Is the Value Tier

Nomad’s Chile ladder is priced more aggressively at the top and it is the reason this page does not simply crown Airalo.

The tiers run from a gigabyte over a week near five dollars through three gigabytes near ten, five near fourteen, ten near twenty-five, and twenty near thirty-nine. That last one is the cheapest twenty-gigabyte tier in the comparison by a wide margin, at under two dollars a gigabyte. There are also two unlimited durations, five days near twenty-six and ten near forty-five, which are expensive per day and only make sense for short heavy use.

For a two-week driving trip with a car and a phone doing navigation, twenty gigabytes is the right size, and Nomad’s price for it is roughly a third less than Airalo’s. That is the strongest single number in this market.

What Nomad does less well is disclosure. Its network partner in Chile is not published as prominently as Airalo’s, and the app is functional rather than polished. Support runs through chat and email and is the most common complaint in public reviews. Its own catalogue is where to confirm the current carriage before you buy.

The trade is straightforward: you are buying the cheapest large allowance and accepting less certainty about which towers carry you. On a city-and-coast trip that is a good trade. On a trip where the road matters, confirm the partner first.

Saily Rides Entel and Sells You a Number Back

Saily is the product built by the NordVPN team, and in Chile it has two features that separate it from the field.

The first is the network. Its Chile plan connects to Entel, which is the network with the deepest rural coverage and therefore the one a driving trip wants. That single fact moves it ahead of Airalo for anyone leaving the cities, before price is considered.

The second is that Saily sells messaging and calls as add-ons on top of the data plan. No other brand in this comparison offers a voice path at all, and for a traveller who needs to receive a bank code or ring a hotel, that is a capability rather than a feature. It is not a full Chilean number in the way a prepaid line is, but it closes a gap the category otherwise leaves open.

The data ladder is five tiers: a gigabyte over a week near five dollars, three over a month near twelve, five near eighteen, ten near twenty-eight and twenty near forty-nine. The middle of that ladder is competitive; the top is not, and Nomad beats it on twenty gigabytes by a clear margin.

The other structural detail worth knowing: Saily’s plans carry a 180-day activation window, which means a plan bought in advance for a trip that slips does not expire. Its official Chile page is the only place with the current price, because resellers quote three different numbers for the same five tiers. The full review goes through the throttle behaviour and the refund window in detail.

Jetpac Has No Chile Pack, Only a Latin America One

Jetpac is the price leader in the category and it does not sell a Chile product at all, which is the first thing to understand about it.

Its Chile coverage comes through a Latin America regional plan covering Chile plus fifteen other countries, sold from a gigabyte over four days at around a dollar up to forty gigabytes over a month. In Chile the underlying network is Claro, which is the middle of the field on rural reach.

That structure is either excellent or irrelevant depending on the trip. For a multi-country South American itinerary it is the cheapest way to cover several borders on one profile. For a Chile-only trip you are paying for countries you will not enter, and the per-gigabyte rate at the small tiers is not better than a country plan.

The trade-offs are consistent with a small company: support is ticket-based, the app is simple, and the network disclosure is thin. The upside is price at the large tiers and a lounge-access perk on delays that reads as a gimmick until a flight is cancelled.

Holafly Sells Unlimited, Which Is a Different Product

Holafly appears in every comparison of this market and it is not a direct substitute for any of the four above.

It sells one thing: unlimited data priced per day, with no allowance to count. For a traveller who does not want to estimate consumption, that removes a decision. For a traveller who would have used ten gigabytes, it is an expensive way to avoid arithmetic.

The catch is specific and worth stating plainly. Holafly’s hotspot allowance is capped per day rather than unlimited, reported in testing at roughly a few hundred megabytes to a gigabyte depending on the tier. On the phone itself unlimited means unlimited; tether a laptop or share with a partner and the ceiling applies. That makes it a good product for one person travelling alone and a poor one for two people in a rental car.

Chile pricing moves with promotions and the brand prices per market, so treat any figure quoted in a review — including this one — as a shape rather than a quote. The comparison that survives is structural: unlimited earns its premium when consumption is genuinely above the fixed tiers, which for most visitors to this country it is not.

What the Price Table Looks Like in October 2026

Every figure below was observed this month and should be read as a shape. This market reprices on promotions that never end, several brands quote different prices on their own affiliate pages than on their store, and the per-gigabyte column assumes you use the whole allowance.

The column that matters is the second one, not the last. A plan on the strongest network at a middling price is worth more to a driving trip than the cheapest plan on the weakest one, and the difference shows up as hours of silence rather than a slightly slower page.

The second column that matters is the shape of the allowance. Fixed tiers end visibly; unlimited tiers end at a speed you did not choose. For anything longer than a week, fixed data with a top-up path is the more predictable instrument.

Why the Per-Gigabyte Column Misleads at the Bottom

Unit price improves with size on every ladder here, so the smallest tier always looks like the worst deal and is often the correct purchase. Four days of city use does not consume a twenty-gigabyte allowance at any pace, and a discount on data you will not open is not a discount. Size the plan to the trip, then compare.

Ten Days in the Central Valley: What to Buy

Model the common trip and the decision mostly makes itself.

Ten days based in Santiago with day trips to Valparaíso, Viña del Mar and one wine valley. Two hours of navigation a day, ride-hailing in the evenings, photo backup restricted to wifi, a couple of video calls to confirm bookings. That lands at five to seven gigabytes.

At that size the spread between the brands is a few dollars and the sensible purchase is a five-gigabyte tier over a month, so the validity never becomes the constraint. Nomad at fourteen dollars, Airalo at fifteen and a half, Saily at eighteen. Any of them works, and the tiebreak should be something other than price: the app you already have installed, or the provider whose support answered your question before you bought.

What is not worth doing here is buying an unlimited plan. The trip will not consume enough to justify it, and the hotspot cap makes it worse for two people sharing.

What is also not worth doing is buying a local prepaid card for a ten-day stay. The physical SIM route requires an identity check, a face scan and an afternoon, and the afternoon costs more than the difference in per-gigabyte rates.

Where the Ranking Reorders Itself on the Road South

On a checkout page the best eSIM for Chile is the smaller number next to the larger one. Four hours south of Santiago it is a different question, and the published numbers explain why.

Measured 4G medians this year put Santiago at roughly eighty to eighty-five megabits, Valparaíso and Viña del Mar in the low sixties, and the provincial capitals of the south in the forties and fifties. Those are not the numbers that decide a driving trip, because a driving trip is not spent in a provincial capital. They are spent on the stretches between them, where the same measurements fall to a few megabits on 3G and occasionally to nothing.

That is the whole argument for putting the network column first. In a city, every brand on this page is fast enough and the spread between them is a rounding error on the bill. Between cities, the spread is not a speed difference, it is whether the map redraws.

The one measured figure that matters most here is corridor coverage rather than peak speed. Entel holds 4G on roughly four fifths of the main highway between Santiago and Puerto Montt, against a materially thinner figure for the two networks behind it. If your itinerary includes that road — and most two-week itineraries do — that single number is worth more than a twenty-dollar saving.

Two practical consequences follow, and neither is about brand loyalty.

The first is that a downloaded map is not a backup for a weak plan, it is the plan for the twenty per cent of the corridor that no brand covers well. Pull the route down for offline use on the first evening, while you still have a hotel network to do it over.

The second is that the plan should be judged by its worst hour rather than its median. A traveller who chose on price will spend the worst hour of the trip looking at a spinning map in a car with no signal, and the eleven dollars saved will feel like the wrong eleven dollars. That is not a hypothetical on this route; it is the ordinary experience of the cheaper wholesale deals.

Two Weeks With a Car: Where Cheap Becomes Expensive

The driving trip is where the network column earns its place and where the cheapest plan becomes the most expensive mistake.

Three things break on a two-week loop. A plan on a network without rural reach produces long silent stretches on the highway south. An unlimited plan priced per day becomes the most expensive option in the market over fourteen days while delivering nothing to someone who would have used fifteen gigabytes. And a plan that runs out on day nine with no top-up path forces a mid-trip purchase at whatever rate is live.

The correct buy is fifteen to twenty gigabytes on the network with the deepest rural footprint, with a top-up path. On this month’s numbers that is Nomad’s twenty at thirty-nine dollars or Saily’s ten at twenty-eight, and the choice between them comes down to whether eight extra gigabytes are worth eleven dollars and a slightly less certain network.

A detail worth planning around rather than arguing about: the weakest signal on any Chilean driving route is between towns, not in them. Download offline maps for the whole route before you leave the first city. It costs a few hundred megabytes once and removes an entire category of problem, including the one where you are looking for a service station with no map.

Which Brands Let You Share, and Which Quietly Charge for It

Sharing is the column where the four brands differ most and where the marketing pages are least informative, so here it is brand by brand.

Airalo permits tethering on its fixed tiers with no separate allowance, and its unlimited line carries the policy of the day rather than a fixed rule. Nomad permits it on fixed plans. Saily advertises no hotspot restriction at all, which is the most permissive position in the field. Jetpac is the one to read carefully, because regional plans carry their own terms and a Latin America product is not the same document as a country plan. Holafly caps the tethered portion per day, which is the only policy here that changes what a shared trip can do.

The reason this matters more than the price column is the shape of a cap. A daily limit of a few hundred megabytes is not a restriction on sharing, it is a restriction on one afternoon of sharing: two people in a car with a laptop on the passenger seat will exhaust it before lunch and then spend the rest of the day on the phone alone.

There is a five-minute test for this, and it is worth doing on the first morning rather than on the day it matters. Check the remaining balance, run a hotspot for ten minutes of ordinary browsing on the second device, and check the balance again. The difference tells you what the plan actually counts, which is often not what the plan page says.

What Does the Fair-Use Clause Actually Say?

Every unlimited product in this category has a threshold described in the plan detail and not on the marketing page, and the post-threshold speed is what determines whether the plan is still useful.

A connection that holds a megabit is still a maps connection. One that drops to a couple of hundred kilobits is a messaging connection and nothing more, and a video call on it fails rather than degrades. Anything described as “reduced speed” without a number should be treated as the second category until proven otherwise.

This matters less in Chile than in some markets because the better-value products here are fixed-data plans, which have a cliff rather than a slope. You know where they end, the app shows the balance, and at zero you buy more. That is a worse headline and a much better instrument.

The rule of thumb: if you plan to work, buy fixed data and manage it. Unlimited is for people who want to stop thinking about data, and thinking is cheaper.

Refunds, Unused Profiles and the Line That Closes

The refund line is drawn in the same place across this entire category: a profile that has never attached to a network is generally refundable within a stated window, and the moment it registers on a Chilean cell it has been consumed.

That is more generous than it first appears. A plan bought and installed but never connected is usually still refundable. A plan that connected once and then failed is not, which is why the diagnostic order matters more than the policy: most “dead” profiles are roaming switched off on the wrong line rather than a broken purchase.

Two habits follow. Screenshot the refund clause at purchase, because the policy page is not reachable without data. And test the profile on airport wifi before leaving the terminal, so a dead plan is discovered while you still have a network to complain over.

What no policy covers is disappointment with speed. A plan that works and is slower than hoped is a working plan.

Buy in September, Install in December: Two Clocks, Not One

The question of when to buy is where a comparison page usually goes quiet, and it is worth an answer because the two clocks in this category are not the same clock.

The first is the purchase clock. The second is the activation clock, and it starts when the profile first attaches to a network in Chile. Validity in days — seven, fifteen, thirty — is counted on the second clock for the products compared here, which means a plan bought months early and installed the night before the flight gets its full allowance in Chile rather than expiring at home.

The licence to buy early is the activation window, and it varies. Saily’s profiles carry a hundred and eighty days from purchase, which is generous enough to cover a trip booked in one season and taken in the next. Airalo and Nomad publish their own windows on the plan detail rather than the marketing page, and the shortest I have seen in this category is thirty days — a number that turns an early purchase into a wasted one if the trip slips a month.

So the practical rule is: buy when the window comfortably covers the gap to your arrival date, and not before. There is no advantage to buying eight months out, and one real disadvantage, which is that the product you bought is the product that existed then.

Two smaller things belong to this decision.

Promotions rotate constantly in this market, so a price bought in a quiet month is often better than one bought in a busy month. That argues for buying a few weeks ahead rather than a few days ahead, which is also when support is least overloaded.

The QR code is a single-use credential. It installs one profile on one handset and cannot be transferred afterwards. Keep the original in cloud storage and treat any forwarded copy the way you would treat a password, because that is what it is.

And if the dates are still uncertain, the honest answer is to wait. A plan bought for a trip that may move has bought you nothing except a refund conversation you will probably lose, since the refund window runs from purchase and is shorter than the activation window.

What Happens If the Window Lapses

An expired profile is not a lost purchase in every case, but it is never an automatic fix. Support can sometimes reissue the same plan and sometimes only sell a new one, and the answer depends on whether the profile was ever installed. Ask before buying early, and keep the answer somewhere you can find it.

What a Provider Must Tell You Before You Pay

Four questions separate a provider that tested its product here from one that localised a template, and all four are answerable in a sentence.

Which network does this plan ride, and does it fall back? Entel, Movistar, Claro or WOM. A provider that names it has a real agreement; one that does not has either not negotiated one or not documented it.

Is there a voice path? Almost always no. Saily’s add-on is the exception in this field, and if you need a Chilean number the answer to this question ends the comparison immediately.

What is the hotspot policy? Unlimited, capped, or none. For two people travelling together this single line changes the total more than the plan price does.

What is the threshold on unlimited plans, and how usable is the speed after it? The terms will say. The marketing page will not.

A fifth, softer criterion is support hours. Chile runs four to six hours behind Europe and two to four ahead of the US west coast depending on the season, so problems surface at awkward times either way. A provider with a real 24-hour channel is worth a few dollars.

The Phone Check That Belongs Before You Pay

Every comparison of the best eSIM for Chile assumes a handset that can hold one, and a surprising share of the disappointed reviews in this category are hardware problems filed as brand problems. Five minutes at home settles it.

Carrier lock. On an iPhone the answer is one screen in: Settings, General, About, and a line called Carrier Lock that should read No SIM restrictions. On Android it sits under network settings with a different name on each manufacturer’s build, and on some handsets only the original carrier can lift it. A locked phone rejects an eSIM exactly as it rejects a plastic one.

Whether the phone does eSIM at all, and how many. Most flagships since 2018 do. The number of profiles they hold differs, and a phone already running a home line plus a work line may have no free slot, which turns a two-dollar saving into a reinstall.

Band 28. The 700 MHz band is what carries distance in this country and the phone has to list it. Most recent handsets do. A mid-range phone from four or five years ago may support eSIM, list every band that matters in Europe, and miss this one — which produces a plan that is fast in Providencia and absent on the road, and a traveller who blames the provider.

What happens when the home line stays live. Two lines at once is the normal configuration and it has three settings behind it: which line carries data, which line carries voice, and whether the phone may switch data to the other line when the first has no signal. That last one silently moves your traffic onto a home tariff at roaming rates. Turn it off before the flight, not after the first bill.

The order matters because the checks are cheap and the consequences are not. A traveller who confirms the lock, the slot, the band and the switching setting has eliminated every failure mode that a refund cannot fix — because the profile will have connected, which closes the refund.

Where Android Hides the Same Answer

The carrier-lock screen is an Apple convenience that most Android builds do not reproduce. The equivalent check sits under network settings, sometimes labelled network operators, and on some handsets only a SIM from another carrier proves the point. If the phone was bought outright, the lock is rarely the problem.

The App You Already Have Is a Legitimate Tiebreak

Once the network and the size are settled, the remaining differences are small, and pretending otherwise produces rankings that flip every month with the promotions.

Having the app installed already matters more than it sounds. Installation happens at home, on a connection you control, and the app is what delivers the QR code, the instructions and the top-up path. A traveller who already owns one of these apps has one fewer thing to learn in the week before a flight.

Top-up behaviour is the second practical difference. A brand whose top-up applies to the existing profile without a reinstall is meaningfully better than one that requires a new installation, because the moment you need a top-up is the moment you least want a fifteen-minute task.

Support quality is the third, and it is difficult to assess before you need it. The honest proxy is whether the provider answered a pre-sales question in a few hours. That tells you more than a review score.

Where a Listing Gives Itself Away

Four signs, in order of how much they tell you.

No named network. If the page will not say Entel, Movistar, Claro or WOM, you cannot predict coverage on the roads that matter, and that is the only coverage question a driving trip has.

A per-gigabyte headline computed from the largest plan. A “from $1.50/GB” banner attached to a forty-gigabyte tier is arithmetic theatre. Check the tier you would actually buy.

Unlimited with no fair-use wording. Not necessarily dishonest, but the absence of a threshold description tells you how the plan behaves on day six.

A price that differs between the provider’s store and its affiliate reviews. This is common in this market and it is not sinister — promotions rotate — but it means the only trustworthy number is the one on the checkout page.

When the Traveller Is Not You

A large share of the purchases in this category are made by someone who will not be on the trip: an adult child setting up a parent’s phone, a group organiser buying four profiles, a company booking for a colleague. The ranking barely changes in that case. The execution changes completely.

The installation has to be rehearsed, not described. An eSIM that arrives as a QR code in an email requires the user to scan it, name the line, set it as the data line and switch roaming on for it. Four steps, each of which produces a support call if it is missed. The reliable method is to install it yourself while the phone is in your hand and the trip is still weeks away, then hand back a phone that only needs the line toggled on at the airport.

The support conversation falls to the buyer. Whichever address paid is the address the provider will deal with, and the person on the ground is the one who cannot reach it. Send them the order number and the support link before departure, not a screenshot of the confirmation page.

A group is not one plan with a hotspot. Four people in one car will exhaust a shared twenty gigabytes faster than the arithmetic suggests, because four phones sync photographs, four phones check maps and at least one streams. Two plans across four people, split so the two phones doing the navigating are on different networks, is more resilient than one large plan with everything tethered to it.

For an older traveller, the voice path is the tiebreak. Someone who will not troubleshoot wants one working phone with a number that can ring a hotel, and Saily’s add-on is the only route to that in this comparison. The data volume matters less. Twenty gigabytes that nobody uses is worse value than five that answer the phone.

None of this changes which product is technically best on paper. It changes which product survives contact with a person who did not read this page, which is the same thing in the end.

The Verdict, Cut by Traveller

Arriving for a long weekend, no car: a five-gigabyte month-long tier from any of the four. Choose on the app you already have. The network does not matter in Santiago and the price spread is a few dollars.

Two weeks with a car, one person: Nomad’s twenty gigabytes at thirty-nine dollars, or Saily’s ten at twenty-eight if you want Entel specifically. Both are defensible; neither is wrong.

Two people, one car: one twenty-gigabyte plan shared, plus an offline map on both phones. Do not buy two plans.

A month or a working trip: a local prepaid thirty-day bundle if you want the cheapest gigabyte and a Chilean number, or a large fixed travel plan if you want to skip the registration afternoon. The comparison of the two routes is the place to settle that.

Chile plus Argentina or Peru: a regional product rather than two country plans. The cross-border page works through which ones actually carry both countries.

What People Still Ask Once the Shortlist Is Built

Does the cheapest plan have worse coverage? Usually, but not because it is cheap — because it rides the network with the smaller rural footprint. Price and network correlate in this market without causing each other.

Can I switch networks after buying? No. The profile is provisioned for specific partners. Switching means buying a different product.

Should I pay extra for 5G? None of these brands sells it as a separate line item, so the question is really about your handset and your route. In dense areas all four deliver it; on the roads where the comparison actually matters, none of them do. Judge the brands on 4G reach.

Will my plan work in the metro? Platforms yes on the newer lines, tunnels no. That is a network fact rather than a brand difference.

Do I need a different plan for the lake district? No. One national plan covers the country; what changes is which network holds signal on the roads between towns.

What if I only need two days of data before a flight home? Buy the smallest tier that covers the days, not the cheapest per gigabyte. This is the one case where a tiny tier at a bad unit price is the right purchase.
