Best eSIM for Colombia? How to Choose One for Your Trip
Last checked: September 2026
To choose an eSIM for Colombia, check your phone is eSIM compatible and unlocked, pick a data size and duration that match your trip, and confirm the networks covered. Slashtel Colombia plans run on Claro, movistar and Tigo with 5G, and you install the eSIM on Wi-Fi before you fly.
What to check before you buy
Before buying an eSIM for Colombia, confirm three things: your phone is eSIM compatible and not locked to a carrier, the plan covers the networks you will use, and the data size and duration match your trip. Slashtel eSIMs are data-only, so there is no phone number, no calls and no SMS, but WhatsApp, FaceTime and other internet calls work over the data.
Start with your handset. Not every phone supports eSIM, and some phones sold in certain markets have it disabled. Use the guide to check your phone is eSIM compatible before you pay for anything. If your phone is locked to a carrier, an eSIM from another provider will not work until the lock is removed.
Next, look at what the plan includes. Slashtel Colombia plans are data-only. That means you keep your home SIM in the phone for calls and bank texts, and use the eSIM purely for mobile data. This is a common setup for travellers because it avoids swapping physical SIM cards and keeps your usual number active for one-time passcodes.
Finally, check the practical details: how the eSIM is delivered, when it activates and how you pay. The eSIM QR code arrives by email within minutes of payment. You install it on Wi-Fi before you travel, and data starts on first connection at your destination. Payment is by Visa, Mastercard, Amex, Apple Pay or Google Pay from any country.
How much data you need
How much data you need depends on trip length and how you use your phone. As a guide, a one week trip can work with 1 GB, two weeks with 3 GB, and one month with 3 GB, but heavier use of maps, video and hotspot needs more. Slashtel Colombia plans come in 1 GB, 3 GB, 5 GB and 10 GB sizes over 7, 15 or 30 days.
Those figures assume light to moderate use: messaging, maps, checking bookings and the occasional photo upload. If you plan to stream video, take video calls without Wi-Fi, or share your connection with a laptop, you will burn through data much faster. A data calculator can help you estimate based on your own habits.
Think about where you will be. In cities and tourist areas, Wi-Fi is widely available in hotels, cafes and restaurants, so you can lean on it for big downloads and video. On long bus journeys, in remote areas or on multi-day treks, you will rely on mobile data alone, so allow extra.
Duration matters as much as size. A 30-day plan with 3 GB suits a month-long trip with regular Wi-Fi access. A 7-day plan with 5 GB or 10 GB suits a shorter trip with heavier use. If you are unsure, start smaller and add more later rather than paying for data you never use.
Networks and coverage
Slashtel Colombia plans connect to Claro, movistar and Tigo, with 5G where available. Coverage is strongest in cities and along main transport routes, and thinner in remote jungle, mountain and coastal areas. Your phone will connect to the available network automatically.
Colombia's mobile coverage is good in Bogota, Medellin, Cali, Cartagena and other major cities, and along most popular tourist routes. Outside those areas, expect gaps. If your itinerary includes the Amazon, the Pacific coast or high mountain regions, download offline maps before you set off and treat mobile data as a bonus rather than a guarantee.
Network availability can vary by location, and your phone chooses the network automatically. You do not normally need to select one manually. If you lose signal, toggling airplane mode on and off, or restarting the phone, often reconnects you to the strongest available network.
5G is available on these networks, but only where it has been rolled out and only if your phone supports the local 5G bands. If you see 4G or LTE instead, that is normal and still fast enough for maps, messaging and most browsing.
Setting it up before you fly
Install your Colombia eSIM on Wi-Fi before you travel. The QR code arrives by email within minutes of payment. Data starts on first connection at your destination, so you can set everything up at home and land ready to connect.
- Buy your plan and wait for the email with the eSIM QR code, which usually arrives within minutes.
- While still on Wi-Fi at home, follow the steps to install an eSIM on iPhone or Android using the QR code.
- Label the new line clearly, for example Colombia, so you can tell it apart from your home SIM.
- Keep your home SIM switched on for calls and bank texts, and set the eSIM as the line for mobile data.
- Turn off data roaming on your home SIM to avoid unexpected charges.
- When you land, switch the eSIM line on if it is not already active. Data starts on first connection.
Menu names for these settings differ by phone model and by country, so the exact wording on your device may not match another phone. Look for the mobile or cellular settings area and follow the labels on your own screen.
Topping up and staying connected
If you run low on data, you can add more to the same eSIM with a top-up. Nothing new needs to be installed. On 30-day plans you can tick Keep me connected, and while you are still using the eSIM the same plan is added when data runs low or the plan is about to end, with an email first and one-click turn-off.
Top-ups are the simplest option when you need a little more data mid-trip. Because the top-up goes onto the eSIM you already have, there is no new QR code and no reinstallation. You buy it, and the extra data is added to your existing plan.
Keep me connected is designed for longer trips where you would rather not think about running out. It only applies to 30-day plans, and only while you are still using the eSIM. You get an email before it happens, and you can turn it off with one click if you no longer need it.
If something goes wrong, support is on WhatsApp, so you can get help without needing a working phone line. Before you travel, it is worth saving your plan details and checking the Colombia eSIM plans page so you know exactly what you bought. Prices are shown live on the plan page.
