eSIM for Colombia

Most trips start at El Dorado airport in Bogotá. Set up the eSIM before you fly, then turn on data when you land and you will have signal while you are still waiting for your bags. No queue at a phone counter, no cash needed.

Bogotá is high in the Andes and packed with people, so Claro coverage here is strong across the city. In La Candelaria, the Gold Museum area, Usaquén and the business zones near Calle 100, you get fast 4G almost everywhere. For a few days of maps, ride apps and messaging in the capital, the 1 GB for 7 days plan at $2.63 is plenty.

Medellín sits in a valley, and the city climbs up the hillsides on both sides. Signal is good in El Poblado, Laureles and the city center, and it even holds up on the Metrocable cars that float over the comunas. The metro and cable lines are a great way to see the city, and you can stay online for the whole ride.

If you are working remotely from Medellín, which a lot of visitors now do, light browsing burns through 1 GB fast. The 3 GB for 30 days plan at $7.35 fits a week or two of normal use with some video calls mixed in.

Cartagena's walled old town is dense and touristy, so Claro data runs well there and around the Bocagrande high rises. You will get steady signal for posting photos, booking tours and finding restaurants in Getsemaní.

It gets patchier once you leave the city. On a boat out to the Rosario Islands, or up the coast toward Santa Marta, the signal drops near the water and comes back near towns. Plan to do your uploads while you still have a bar or two.

The Zona Cafetera spreads across the towns of Pereira, Armenia and Manizales, with Salento and the Cocora Valley as the big draws. In the towns themselves the signal is fine. Up among the coffee farms and the tall wax palms of Cocora, expect it to fade in and out as you wind through the hills.

Download your offline maps and your hike route before you head into the valley. A short stay here pairs well with a small plan, but if you are touring several towns over two weeks, the 3 GB for 15 days plan at $7.14 covers the moving around.

Cali is flat, hot and easy to get around, and Claro coverage across the city is solid for salsa club hunting and getting from one barrio to the next. The airport and the main avenues all have good data.

Head west toward the Pacific coast and places like Buenaventura or the whale watching spots near Nuquí, and you move into much thinner coverage. The Pacific is remote and wet, so treat any signal there as a bonus and sort out your plans before you go.

Tayrona National Park near Santa Marta is one of the prettiest spots in the country, and it is also where your phone goes quiet. Inside the park and on the trails to beaches like Cabo San Juan, signal is weak to none.

The same goes for the multi day trek to Ciudad Perdida, the Lost City. You will be off grid for most of it. Use the data you have in Santa Marta to message family, then enjoy being unreachable. This is exactly why a prepaid plan that does not bill you by the minute makes sense here.

Leticia, the gateway to the Colombian Amazon, has basic data in town, but it thins out fast once you are on the river or in the jungle lodges. Coverage there is not something to count on.

San Andrés and Providencia, the islands in the Caribbean, have signal in the main town and tourist strips, though it can be slow when the island is busy. For a beach trip where you mostly want maps and a few uploads, a small plan is enough, and you can top up later if you run low.

For a short city break with maps, chat and ride apps, start with 1 GB for 7 days at $2.63. For a one or two week trip touring several regions, the 3 GB for 30 days at $7.35 is the sweet spot. If you stream music on long bus rides or work online, jump to the 5 GB for 30 days at $14.00 or the 10 GB for 30 days at $25.55.

Setup is quick. Buy the plan, get the QR code by email, then open your phone settings and add the eSIM by scanning that code. Do this on home Wi Fi before your flight. When you reach Colombia, switch the MegaEsim line on for data and turn data roaming on for that line. Your home number stays in place for calls and texts.

Compared with airport roaming from your home carrier, which can run several dollars a day, or buying a local Claro SIM in person, the eSIM saves you time and you set it up before you ever leave home.
