In short: the eSIM for Medellín is actually the eSIM for Colombia, because coverage works by country, not by city. Install it before flying using your home Wi-Fi, activate it upon landing at José María Córdova Airport (Rionegro), and you'll have data for the transfer to El Poblado, the metro, Comuna 13, and the excursion to Guatapé, without roaming or physical SIM cards.
What it is and how to install it before flying
An eSIM is a digital SIM card installed as a profile on your phone, without a tray or plastic to insert. For Medellín, specifically, you buy the Colombia eSIM: you scan a QR code or install it with a link, and your mobile is ready to connect to the country's network as soon as you arrive. No physical store is needed, nor do you need to remove your Spanish SIM from the device.
The crucial step is to install it before leaving home, with the peaceful Wi-Fi of your living room and without rushing. If you leave it for your departure airport or, worse, for when you're already in Rionegro, you'll depend on public Wi-Fi that might fail just when you need it most. Installing is not the same as activating: the profile is installed in Spain and remains "asleep" until you decide to turn on that data, usually once you're in Colombia. If you've never done this before, you can find the complete step-by-step guide in how to install an eSIM, with screenshots for iPhone and Android.
From José María Córdova Airport to El Poblado
José María Córdova Airport (MDE) is not in Medellín but in Rionegro, a neighboring municipality about 35 km away. The journey to the city takes about an hour by car because you have to cross the mountain on a winding road. This is one reason why it's worth arriving with active data: during that journey, you'll want to request a transfer via an app, confirm the exact accommodation address, and, if someone is waiting for you, notify them that you've landed.
As soon as you step into the terminal, turn off airplane mode, activate the eSIM data line (not the call line, which is still your Spanish one), and wait a few seconds for your phone to connect to the Colombian network. One detail many people miss: if you have dual SIM activated, check that your phone uses the eSIM for mobile data and your physical SIM only for calls. Otherwise, your phone might try to use roaming data from the Spanish line without you realizing it, potentially incurring an unexpected charge. Most travelers stay in El Poblado or Laureles, two areas with good coverage from the very first minute, so maps and Uber work smoothly right after leaving the terminal.
eSIM or roaming: which is better in Colombia
Roaming with your Spanish operator outside the European Union usually incurs a cost that escalates with the number of days you're away, and it's difficult to calculate in advance how much you'll pay because it depends on opaque per-megabyte or daily block rates. Before deciding, it's worth understanding what data roaming is and why the rules outside the EU differ so much from what you're used to when traveling in Europe.
The eSIM, on the other hand, is a fixed plan: you know in advance how many GB you have and for how long, with no surprises on your bill when you return. And here we must be honest: if your trip to Medellín is a short stopover and you won't leave the airport transit area, you don't need to buy anything; the airport's Wi-Fi will be enough. The eSIM makes sense as soon as you go out, move around the city, or need data outside your hotel's Wi-Fi. If you want to see more details, in eSIM vs. roaming, we compare the two options in depth.
Real traveler tip: do not activate the eSIM until you are in Colombia. Most plans start counting days from the first network connection, not from when you buy it, so if you turn it on in Spain, you're burning an entire day before you've even left home.
Real coverage: Comuna 13, metro, and Metrocable
Medellín has a solid telecommunications infrastructure for a city its size, and the signal is good in most tourist areas. Comuna 13, with its escalators, murals, and graffiti, has sufficient coverage for photos, videos, and maps throughout most of the usual itinerary, so you can do the tour independently without relying on a guide with their own connection. You should be careful in the narrower alleys further away from the main route, where the comuna's uneven terrain can cause the signal to drop temporarily: nothing serious, but if you're going to record something important, do it in the open areas of the route.
The Medellín metro, the only one in Colombia and a source of local pride, has good coverage in stations and for much of the above-ground route. The Metrocable, which goes up to neighborhoods like Santo Domingo or to Parque Arví, maintains a signal as you ascend, so you can record the city views without interruption. In El Poblado and Laureles, with their density of cafes and co-working spaces, 4G is stable throughout the day, and in the center, around Pueblito Paisa or the Botanical Garden, you'll also be connected without problems. With the eSIM, you connect to local mobile networks just like a local Colombian user, without guest rates or public Wi-Fi limits.
Excursion to Guatapé and El Peñol Rock
The almost obligatory day trip from Medellín is to Guatapé and climbing El Peñol Rock, about two hours by road through reservoirs and mountains. In the town of Guatapé itself, with its colorful zócalo facades, and at the base and summit of the Rock, coverage is usually sufficient for maps and photos: it's one of the most visited tourist areas in the department, and the infrastructure responds. The signal might fluctuate on the mountain road sections between Medellín and Guatapé, with sharp curves and sparse population.
The practical advice is to download the route map offline before leaving Medellín, with the eSIM already active, in case any section loses coverage for a while. That way, even if you momentarily lose signal on the road, you won't rely on it to avoid getting lost. With that, you'll be well-covered for a full-day excursion. And if your itinerary doesn't end in Colombia but continues on a backpacking route south, check out our eSIM guide for Peru and Machu Picchu, because you'll need a new line when crossing countries, even if you use the same phone.
How many GB to get depending on your trip type
Medellín has become one of the favorite destinations for Spanish-speaking digital nomads, so actual consumption varies greatly depending on what you do. If you're purely a tourist, relying on your accommodation's Wi-Fi at night, a little will be more than enough. If you're coming to work remotely with daily video calls and sharing your hotspot with your laptop, consumption skyrockets, and it's wise to plan with a margin. This table guides you according to your travel profile:
| Traveler Type | Typical Duration | Estimated Data |
|---|---|---|
| Tourist (maps, photos, Uber, social media) | 4-6 days | 5 GB |
| Long Stay (tourism + some occasional work) | 1-2 weeks | 10 GB |
| Digital Nomad (video calls, daily hotspot, streaming) | 2-4 weeks | 15-20 GB or more |
A trick that saves quite a few GB without you noticing it in the experience: lower the upload quality on social media when you're on 4G and save high-quality streaming for when you have Wi-Fi at your accommodation. If you're staying for weeks in El Poblado or Laureles working from cafes, you'll be interested in our guide to tricks to save data with an eSIM, because hotspots and video calls consume more than most people initially calculate.
What almost no one tells you
There are a series of small details that are not in general Colombia guides but make a difference when you are on the ground in Medellín:
The myth of "I need a local chip to make it cheaper." In Medellín, there are prepaid chip stands at the airport and in the city center, but they involve queuing, sometimes registering identity documents depending on the operator, and losing minutes you won't get back. The eSIM avoids all that, and if something goes wrong, you reinstall it from the confirmation email without leaving your hostel sofa.
The taxi or Uber asks for a precise location before you activate data. If you leave the Rionegro terminal without the eSIM already active, your phone's GPS may take time to pinpoint your exact position, and the driver will receive an imprecise pick-up address. Activate data inside the terminal, before going to the pick-up area, and allow time for the map to settle.
A restart solves most scares. If, upon landing, you activate the eSIM and it doesn't connect, before thinking something went wrong, restart your phone. Often, the phone remains connected to the antenna from before landing, and a simple restart resolves it in seconds.
In rural areas near Guatapé, accommodation might not have decent Wi-Fi. Fincas and cabins by the reservoir sometimes only offer basic or non-existent Wi-Fi, so your eSIM becomes the main connection, not the backup: factor that into the GB you bring if you plan to sleep outside Medellín.
When NOT to buy anything. If your stop in Colombia is a short layover without leaving the airport, or if you already have cheap roaming contracted with your operator for Latin America and you've confirmed it covers Colombia well, compare the price before adding another line: for two or three scattered days, it sometimes doesn't pay off, and it's honest to tell you before you buy something you won't get your money's worth from.
Why you buy the Colombia eSIM and not a "Medellín" one
Although you might literally search for "eSIM Medellín," what exists and what you will install is the Colombia eSIM: there are no data plans by city, because operators sell national coverage. And this is an advantage, not a limitation, because with that same line you have data in Medellín and, if your route extends to Cartagena, Bogotá, the Coffee Region, or any other point in the country, you don't need to buy anything new or reinstall another profile.
If your trip includes several Colombian cities, you might be more interested in our general guide to eSIM for Colombia: Medellín, Bogotá, and Cartagena, designed for itineraries that don't just stay in the Paisa capital. And if your outbound or return flight has a stopover in another country before arriving in Colombia, also check if you need coverage during that stopover: for legs through the United States, there is the United States eSIM, and for stopovers within Europe, the Europe eSIM, both independent of the line you use in Colombia.
In summary, the correct product for Medellín is the Colombia eSIM, the same one that covers the rest of the country if your route expands. Install it before leaving home, activate it upon landing in Rionegro, and forget about roaming for the rest of your trip.
Frequently asked questions
Is there an eSIM just for Medellín?
No. Medellín is a city in Colombia, so the country's eSIM is used, with national coverage. That same line works in Medellín, Cartagena, Bogotá, and the rest of Colombia, giving you freedom if your trip includes several cities or excursions like Guatapé.
Is there coverage in Comuna 13 and the Metrocable?
Yes, generally. In Comuna 13, you'll have a signal for maps and photos throughout most of the usual tourist route, although it may drop temporarily in alleys further away from the main route. On the metro and Metrocable, coverage is good in stations and for much of the journey, including the ascent to the hills.
How many GB do I need if I work remotely from Medellín?
For tourism, 5 GB over several days is usually enough, relying on your accommodation's Wi-Fi at night. If you're a digital nomad with daily video calls and use your hotspot for your laptop, increase to 15-20 GB or more, because video meetings and sharing your connection consume much more than most people expect.
Does the eSIM work as soon as I leave Rionegro Airport?
Yes, if you installed it beforehand with Wi-Fi. Upon landing at José María Córdova, you just need to turn off airplane mode and activate the eSIM's data; it connects to the Colombian network in seconds. This is especially useful because there's almost an hour's drive to Medellín, and you'll want to be connected during that time.
Do I keep my Spanish number while in Colombia?
Yes. The eSIM is a second line dedicated to data, so your Spanish SIM remains active for calls and SMS in its physical slot. You can have both working simultaneously: the eSIM for internet and your usual number for important matters, without having to choose one or the other.
What happens if my flight has a layover in another country before arriving in Medellín?
The Colombia eSIM only provides coverage within Colombia, so if your layover is long and you plan to leave the transit airport, you'll need separate coverage for that country. Check your layover destination: if it's in the United States or a European country, there are specific lines for those legs, independent of the one you use in Colombia.
Is it worth buying an eSIM if I'm only in Medellín for two days?
It depends on how much you plan to move around. If you leave your accommodation, use Uber, maps, and want to do Comuna 13 or the metro on your own, it's worth it compared to roaming. If you're mostly staying at the hotel with Wi-Fi and only going out accompanied, perhaps occasional roaming from your operator will be enough for those two days.
Conclusion
Medellín is best explored by metro, Metrocable, and Uber, and all of that requires being connected from minute one, even more so if you're also coming to work remotely. Remember that what you buy is the Colombia eSIM, valid in Medellín and any other stop in the country that crosses your path. Install it before you fly, activate it upon landing in Rionegro, and forget about roaming for the rest of your trip. Arrive in Medellín connected and move around the city without last-minute hassles.
