Buy a local Ecuadorian SIM if you are heading into the Amazon, because Claro is the only network with real reach there and no mainstream travel eSIM sells it. That is the one genuinely functional reason to queue at a counter here, and it is a better reason than price. Ecuador's prepaid market is cheap but not spectacularly so by regional standards: airport counters sell 6 to 12 GB over 30 days for roughly 6 to 12 dollars, and since the country uses the US dollar those figures compare directly against a travel eSIM with no conversion in between. Everything else about the decision is shaped by two facts most guides have not caught up with: Movistar is being rebranded to Tigo, and the state operator CNT is the one leading on 5G.

Three Networks, One of Which Is Changing Its Name
Ecuador has three mobile operators and, as of 2026, one of them is mid-rebrand. Claro, the America Movil business, is the clear leader with 52.9 percent of the market in the first quarter of 2026 and around 11,800 base stations, backed by a 597 million dollar parent-company commitment to defend that position with 5G. Movistar holds about 29.5 percent. CNT, the state-owned operator, has 17.6 percent.
The change: Telefonica sold its Ecuadorian unit, Otecel, to Millicom for 380 million dollars and is exiting the country. Movistar and Tuenti are being replaced by Tigo, with 3.7 million subscribers migrating to Millicom's billing platform and shopfronts already being rebranded. If you arrive and find a Tigo store where a guide promised you a Movistar one, that is why. The network underneath is the same.
CNT leads on 5G, which surprises people
The state operator is the one ahead here. CNT had 422 5G base stations by 2026 with live service in Quito and Guayaquil and a target of national coverage by the end of the year. Claro had deployed 99 antennas in the 3.3 GHz band by the end of 2025, covering Guayaquil, Quito, Coca and Puerto Ayora in the Galapagos, and both Claro and Movistar began wider rollout in the first quarter of 2026. It is still early, and 4G is what you will actually use across most of the country.
Claro Ecuador
Claro is the network to buy if coverage is the priority and your route is ambitious. Its 11,800 base stations are the largest deployment in the country by a wide margin, and that shows up exactly where you would expect: in the Oriente, on the smaller highland roads, and in places that were never going to justify a tower on commercial grounds alone.
It is also the network you cannot get any other way. Every mainstream travel eSIM sold for Ecuador rides Otecel, the Movistar network. Airalo names Otecel, Nomad lists Movistar, Holafly partnered with Movistar. None of them offer Claro. So if your itinerary includes an Amazon lodge downriver from Coca, or serious time off the Pan-American Highway, walking to a Claro counter with your passport is the only route onto the network best equipped to serve you.
Claro also has 5G, live in Guayaquil, Quito, Coca and Puerto Ayora. The inclusion of Coca in that list is telling: it is a small Amazon gateway town, and Claro putting 5G there rather than in a larger highland city says a lot about where it has chosen to invest.
Movistar, Now Becoming Tigo
Movistar is the second network and, for a visitor, the one you will almost certainly be using whether or not you choose it, because it is the network behind every mainstream travel eSIM for Ecuador. That makes its performance more relevant than its market share suggests.
The reassuring part: Movistar recorded the highest measured service quality of the Ecuadorian operators in mid-2026 assessments. It is not the biggest network but it is a good one, and it covers Quito, Guayaquil, Cuenca, the highland corridor through Otavalo, Ambato, Banos and Riobamba, and the main Galapagos towns without difficulty. For a standard Ecuador itinerary you would never notice you were not on Claro.
What the Tigo transition means practically
Millicom paid 380 million dollars for Otecel and is migrating 3.7 million subscribers onto its own platform while rebranding the retail estate. For a short-stay visitor this is essentially invisible: the towers, the spectrum and the coverage do not change when a logo does. It matters mainly for reading older guides, which will describe a four-operator market that no longer exists, and for finding a shop, since the sign may say something different from what you searched for.
CNT, the State Operator
CNT is the smallest of the three at 17.6 percent of the market and the easiest to overlook, which would be a mistake in one specific respect: it is the country's 5G leader, with 422 base stations by 2026 and a stated goal of national coverage by the end of the year.
As a practical purchase for a traveller, CNT is a mixed proposition. Its urban coverage in Quito and Guayaquil is good and its 5G is the most developed in the country. Its rural footprint is thinner than Claro's. Its counter presence at Mariscal Sucre airport means you can buy it on arrival alongside the other two. For most visitors it is a reasonable third choice rather than a first, and worth considering if you are staying put in a city, need genuine bandwidth, and want the best chance of catching 5G.
Being state-owned, CNT also carries a public-service coverage mandate in some rural areas, which occasionally makes it useful in places the private operators skipped. That is not consistent enough to plan a trip around.
Passport, Form and What to Expect at the Counter
Ecuador registers prepaid lines, and the process is slightly more formal than in some neighbouring countries: you need your passport and you will be asked to complete a registration form rather than just handing over a document for a scan.
Buying a SIM in Ecuador
1. Bring your passport. Not a copy, and not a driving licence.
2. Choose the network before the package. Claro for reach, Movistar or Tigo for balanced quality, CNT for urban 5G.
3. Fill in the registration form. Allow a few extra minutes for this after a long flight.
4. Pay in US dollars, which is simply the currency. Small denominations are useful across Ecuador generally.
5. Confirm data is working before you leave the counter.
The hours matter more than the paperwork. The kiosks at Mariscal Sucre airport typically run from about 6am to 10pm, and Quito receives a meaningful number of late-evening arrivals. Landing at 11pm means the counters are closed, the city is 43 kilometres away and you are making transfer decisions without data. That is the single scenario where paying more for a travel eSIM is straightforwardly the better call.
Ecuadorian Prepaid Options Side by Side
| Option | Network | Representative price | Best for |
|---|---|---|---|
| Airport counter package | Claro, Movistar or CNT | 6 to 12 USD for 6 to 12 GB, 30 days | Daytime arrivals with a passport to hand |
| Claro local SIM | Claro | Similar, bought in city shops | Amazon travel and remote highland routes |
| CNT local SIM | CNT | Similar | City stays where 5G is genuinely useful |
| Travel eSIM, metered | Movistar / Otecel | Roughly 5 to 10 USD for a typical trip | Most visitors on trips up to a month |
| Travel eSIM, unlimited | Movistar | Priced per day | City-heavy trips with constant data use |
The gap here is narrower than in most countries, which is worth saying plainly. Ecuadorian counter prices are fair rather than astonishing, and a travel eSIM is not the expensive luxury option it can be elsewhere in the region. The deciding factors are network access, arrival time and whether you want to do paperwork.
Where to Buy a SIM in Ecuador
Mariscal Sucre airport, Quito. Counters for all three networks in the arrivals hall, roughly 6am to 10pm. Convenient if you land in daylight. The Quito airport guide covers the layout and the 43 kilometre run into the city.
Quito city shops. All three operators have branches in the northern malls, Quicentro and El Jardin among them, and along Avenida Amazonas. This is the reliable route, with staff who can resolve an activation problem rather than a kiosk that cannot.
Guayaquil and Cuenca. Both have full operator presence. Guayaquil is where the strongest coverage in the country sits, and Cuenca has a large long-stay foreign population that makes shop staff used to helping visitors.
Topping up around the country
Recharges are sold in pharmacies, corner shops and supermarkets nationwide, and all three operators take card payments through their apps. Because Ecuador uses the dollar, top-up denominations are in familiar amounts and there is no confusion about minimum values. Do carry small bills generally in Ecuador, since change for large notes can be scarce outside the cities.
eSIM or Local Card for Ecuador?
Ecuador is one of the closer calls covered on this site, because the local counter prices are moderate rather than dramatically cheap and the paperwork is slightly heavier than average. The decision turns on where you are going and when you land.
Buy local when
Buy an eSIM when
One planning note that applies whichever you choose: Ecuador itineraries contain a lot of genuinely offline time. Every hour on a Galapagos boat, every stretch of high paramo around Cotopaxi or Quilotoa, every river leg past Coca. Those days consume no data, which is why a modest plan goes further here than the trip length implies. The eSIM Finder accounts for that.
Practical Ecuador Connectivity Notes
The dollar makes comparison honest. Ecuador adopted the US dollar in 2000 and everything is priced in it, so a 10 dollar counter package and a 10 dollar eSIM plan are directly comparable with no spread hidden in a conversion. Few countries make the arithmetic this clean.
The Galapagos are a special case. Puerto Ayora, Puerto Baquerizo Moreno and Puerto Villamil have workable 4G, strongest along the waterfront and thinning inland. The water between islands has nothing, which includes every liveaboard cruise, most inter-island day tours and the fast public ferries. A cruise-based Galapagos trip barely needs a data plan at all.
Brand names are shifting. Movistar is becoming Tigo under Millicom. Anything written before 2026 describing Ecuador's operator landscape needs reading with that in mind, including which shopfront to look for.
Claro is the only real coverage upgrade available. Since every travel eSIM here rides Movistar, the one way to buy genuinely better reach is a local Claro card. That is worth doing for an Amazon leg and unnecessary for anything else.
Offline maps before every high-altitude day. Cotopaxi, Quilotoa and the passes toward the Oriente all have long dead stretches, and weather at altitude changes fast. The Quito city guide covers which day trips keep you connected and which do not.
Frequently Asked Questions
Which Ecuadorian network should I buy?
Claro if your trip includes the Amazon or serious back-road highland travel, because its roughly 11,800 base stations give it reach the others do not match, and it is the only way onto that network since no travel eSIM offers it. Movistar, soon Tigo, if you want balanced quality on a normal itinerary, and it recorded the highest measured service quality of the three in 2026. CNT if you are staying in Quito or Guayaquil and want the best shot at 5G, where it leads with 422 base stations.
How much does a prepaid SIM cost in Ecuador?
Airport counters typically sell 6 to 12 GB valid for 30 days at around 6 to 12 US dollars, and city shops are similar. Ecuador uses the dollar as its currency, so those are actual prices rather than converted ones and they compare directly against travel eSIM pricing. You will need your passport and to complete a registration form, which takes a few minutes longer than the passport-scan process used in some neighbouring countries.
Why is Movistar turning into Tigo?
Because Telefonica sold its Ecuadorian operating company, Otecel, to Millicom for 380 million dollars and is exiting the country. Millicom trades as Tigo, so the Movistar and Tuenti brands are being retired here, with 3.7 million subscribers migrating to Millicom's billing platform and stores being rebranded. Nothing about the physical network changes, so a Movistar-based travel eSIM keeps working exactly as before. It mainly means older guides and the shop signage will disagree for a while.
Will my SIM work in the Galapagos?
In the towns, yes, and an Ecuadorian mainland SIM works there as domestic service. Puerto Ayora on Santa Cruz, Puerto Baquerizo Moreno on San Cristobal and Puerto Villamil on Isabela all have usable 4G, best along the waterfront and weaker inland. On the water there is nothing at all: liveaboard cruises, inter-island day tours and the fast public ferries are entirely offline. Plan for that rather than assuming an island package will fix it.
Do I need a local SIM if I already have a travel eSIM?
Only for one scenario worth taking seriously: the Oriente. Every mainstream travel eSIM for Ecuador rides Movistar, and Claro is the operator that built out furthest into the Amazon region, with 5G even in Coca. If you are heading downriver to a jungle lodge, adding a cheap Claro SIM alongside your eSIM is sensible insurance. For Quito, the highlands, Guayaquil, Cuenca and the Galapagos towns, one line is plenty.
