eSIM for Colombia: Bogota, Medellin, Cartagena — three cities, three needs
A typical Colombia trip covers three very different cities in one visit: high-altitude Bogota, Medellin's mild climate, and hot colonial Cartagena on the coast. Each has its own pace and its own demands on your phone, and part of the trip might also involve remote work from a laptop in a cafe. Here's connectivity, city by city.
Bogota: altitude, traffic and a city of districts, not one center
Bogota spans several million people and sits above two thousand meters, so mild shortness of breath during brisk walking or a hill climb is common in the first few days — worth factoring in when planning walks around the historic La Candelaria district. The city has no single tourist center: Chapinero, Usaquen and La Candelaria each run at their own pace, and you'll need your phone constantly for navigating between them, finding a restaurant, and booking a ride.
Riding the Monserrate cable car or hiking up gives a great view over the whole city, but the route up the mountain can have patchy signal — save the cable car's operating hours and the entrance address beforehand.
Medellin: a city for more than a week-long visit
With its mild climate and the Poblado district, Medellin has long been a place people go to work remotely for a month or longer, not just sightsee. For that kind of trip, what matters isn't a couple of days of tourist connectivity but a steady plan with enough data for the whole stay — video calls, cloud services and messaging a team use noticeably more data than a typical sightseeing day.
The Metrocable, which links the center to hillside neighborhoods, isn't a tourist ride but part of the city's transit system, and the trip often takes a while with good views over the city below.
- Bogota — active navigation between districts, frequent rides
- Medellin — steady connectivity for the whole remote-work stay
- Cartagena — mostly used in the old town and nearby beaches
- Coffee region (Salento, Filandia) — signal can be weaker among the hills
Cartagena and the Rosario islands: a colonial city and a beach day
Cartagena is a colorful walled old town where your phone's main job is navigating narrow streets, translating a menu, and booking a ride to the airport in the heat. Coverage in the historic center itself is usually solid, but a day trip to the Rosario islands by boat runs with patchy signal on open water, much like similar boat excursions elsewhere in the Caribbean.
The contrast between the humid coast and cool, high-altitude Bogota shows up not just in what you pack, but in how much time your phone spends in direct sun — on a beach day, it's worth saving battery, not just data.
Booking rides and translating Spanish in Colombia
In the major cities — Bogota, Medellin, Cartagena — ride-hailing apps work as expected and are generally seen as more convenient than hailing a car off the street, especially at night. English isn't spoken everywhere outside tourist areas, so a phone translator gets frequent use in cafes, markets and with drivers — one of the most common reasons data gets used on a trip like this.
In some situations it's sensible to be discreet about using your phone in public — keeping it in a pocket rather than out in the open, especially on intercity buses or in crowded places.
Download offline maps for each city beforehand — Bogota, Medellin and Cartagena are all large enough that memory alone won't cut it.
One plan for a multi-city trip
Since the route usually involves domestic flights between cities, it's simpler to take one data package for the whole trip rather than buying connectivity again in every city. Usage in Medellin during remote work will be higher than on a beach day in Cartagena, so a combined itinerary is worth planning for with some extra headroom.
