Using mobile data in Colombia: what to expect
Colombia's networks have come a long way, and for travellers the day-to-day experience in the cities is genuinely good. Claro, Movistar and Tigo (with WOM and others competing on price) carry the bulk of the traffic, and between them they deliver dependable 4G across Bogotá, Medellín, Cali, Barranquilla and Cartagena, with 5G now switched on in the larger metros. For everything most visitors do — Google Maps to navigate the steep hills of Medellín and Bogotá's grid, WhatsApp for absolutely everything (Colombians genuinely run their lives, their businesses and their family chats on it), Uber and the local Didi, inDrive and Cabify for getting around, and Google Translate when your Spanish runs out — you'll have fast, steady data in town. A travel eSIM means you skip the SIM-shop queue and the passport-photocopy registration that buying a local prepaid SIM can involve, and you avoid the eye-watering pay-per-megabyte roaming bills your home carrier would charge in South America. You also keep your usual number live the whole time, which matters when your bank wants to text you a code.
Coverage across Colombia
The strong signal follows the population and the main road corridors: the Bogotá savanna and the capital itself, the Aburrá Valley around Medellín, the Cali area in the southwest, the Caribbean coast through Cartagena, Barranquilla and Santa Marta, and the Coffee Region (Eje Cafetero) towns of Salento, Armenia, Pereira and Manizales. The colonial streets and walled city of Cartagena are well covered, as are the cable-car lines up Medellín's hillside comunas. Where coverage genuinely drops off is the country's wilder, more mountainous and forested geography — the dense Amazon south around Leticia, much of the Pacific coast around Chocó, Bahía Solano and Nuquí where infrastructure is sparse, the high páramo passes above the tree line, and remote stretches of the eastern Llanos plains. On the winding intercity bus routes through the three Andean cordilleras you'll move in and out of signal as the road climbs and tunnels, so a downloaded map is wise. If you're trekking to the Lost City (Ciudad Perdida) over several days, or off in Tayrona National Park's backcountry beaches, treat yourself as offline and save your routes and key addresses in advance.
How much data you'll need
City-based Colombia travel is moderate on data. WhatsApp messaging and voice calls, Maps, ride-hailing, Instagram and Reels, and the odd camera-Translate session in a market add up gently rather than spiking — though because so much communication happens over WhatsApp voice and video here, that can nudge your usage up. As a rough guide: a long weekend in Bogotá or Cartagena runs around 3-5 GB; one to two weeks looping Bogotá, Medellín, the Coffee Region and the coast typically lands in the 10-20 GB range; and if you stream music on long overnight bus rides or video-call home every day, step up to a larger or unlimited-style allowance. The plans above are organised by those bands — match the allowance to how connected you actually need to be, rather than defaulting to the maximum.
Keep your number and WhatsApp
Your phone can run the travel eSIM and your normal SIM side by side. Set the eSIM to handle data and leave your home number live for calls, SMS and the security codes your bank texts you. Because WhatsApp is tied to your home number, not to whichever SIM has data, your contacts keep reaching you exactly as before — which matters a lot in a country where WhatsApp is the default way to talk to hotels, drivers and tour operators. Just turn your home SIM's data roaming off so it can't generate charges while the eSIM carries the load.
Before you fly
Check that your phone is eSIM-capable first — most iPhones from the XR up, plus recent Samsung Galaxy, Google Pixel and various Motorola and Honor handsets. Our compatibility checker confirms it in seconds. Install the eSIM on home Wi-Fi before you leave; it activates on arrival, so you land at Bogotá El Dorado (BOG), Medellín Rionegro (MDE) or Cartagena (CTG) already online — handy for booking that first Uber out of the terminal without scrambling for airport Wi-Fi.
Heading deeper into the region?
If Colombia is one leg of a wider South or Central American trip, a single-country plan keeps things simple here while you decide on coverage for neighbours like a Ecuador eSIM or onward stops — one less thing to sort at each border.
