About connectivity in Cartagena
Arriving and Getting Online
Your journey to Cartagena will likely begin at Rafael Núñez International Airport (CTG), the Cartagena de Indias Cruise Terminal, or the Terminal de Transportes de Cartagena. With an eSIM installed before your trip, your phone connects to a local network the moment you arrive. This means you can book a ride-share, check your hotel reservation, or message family without having to hunt for a SIM card vendor or rely on spotty airport Wi-Fi.
Navigating Cartagena's Neighborhoods
From the cobblestone streets of the Walled City (Centro Histórico) to the vibrant murals of Getsemaní, reliable data is your best guide. You'll want seamless connectivity whether you're relaxing on the beaches of Bocagrande, dining in the charming plazas of San Diego, or exploring the residential feel of El Laguito. Major Colombian carriers provide strong coverage across these key tourist areas, so your eSIM will keep you connected for maps, translations, and sharing photos.
The Reality of Local Wi-Fi
While public Wi-Fi is available, it's not always dependable. You can find decent connections in cafes in tourist-heavy areas and most hotels offer it to guests, but quality varies. Free public Wi-Fi in parks or shopping malls can be slow and less secure. For consistent, secure internet access—especially for booking transport or accessing banking apps—your own mobile data connection via an eSIM is far more reliable.
Language and Transactions
Spanish is the official language. While English is common in hotels and restaurants within the Walled City, you'll find it less spoken by taxi drivers and local vendors. An eSIM gives you instant access to translation apps, which is invaluable for everything from ordering food to asking for directions. It also ensures you can manage online banking and digital payments in the local currency, the Colombian Peso (COP), without needing to find a secure Wi-Fi network.
Estimating Your Data Needs
A typical tourist using maps, social media, and light browsing will use around 700 MB/day. If you're a business traveler attending meetings and using cloud services, plan for closer to 1.5 GB/day. For digital nomads relying on a mobile hotspot, usage could be 4 GB/day or more. Choosing a plan from a provider like Cellesim that matches this usage prevents you from running out of data mid-trip.
Mobile carrier coverage
In Cartagena, your eSIM will connect to one of Colombia's primary mobile operators. The experience is generally reliable, especially in the main tourist districts. Marketplaces like Cellesim typically partner with the top-tier carriers to ensure you get the best possible service.
The dominant operator is Claro, known for having the most extensive geographical coverage across Colombia, making it a very safe bet. Tigo and WOM are strong competitors within Cartagena, with WOM often cited for having the fastest average download speeds in the city. Movistar is another major player, though its coverage can be less consistent once you venture outside the main urban areas.
| Carrier | Coverage | Notes |
|---|---|---|
| Claro | excellent | The widest geographical coverage; a safe all-around choice. |
| Tigo | good | Strong performance in major cities like Cartagena. |
| WOM | good | Users experienced the fastest average download speeds in a 2022 study. |
| Movistar | fair | Coverage can be less reliable outside of urban centers. |

Pitfalls to avoid
One of the most common mistakes travelers make is buying a physical SIM card at the airport. These are often sold at a significant markup, sometimes 20% to 50% more than what you'd pay in the city. Furthermore, Colombian regulations require anyone using a physical local SIM to register it with their passport and may even require registering your phone's IMEI number to prevent it from being blocked after 30 days. An eSIM completely bypasses this bureaucratic process, saving you time and potential headaches.
Beyond connectivity, having reliable data from an eSIM can help you avoid other common tourist traps. In areas like the Bocagrande beaches, overcharging for services is a known issue. With data, you can quickly check reviews or standard prices. Similarly, instead of hailing unlicensed taxis that may quote inflated fares, you can use a reputable ride-hailing app. Your eSIM ensures you have the tools to navigate Cartagena safely and confidently, avoiding scams that prey on disconnected tourists.
Frequently asked questions

Can I use my eSIM to get a taxi from the airport?
Absolutely. Your eSIM can be activated as soon as you land, giving you immediate data to use ride-hailing apps. This helps you avoid negotiating with unlicensed taxis and secures a fair price.
What happens if I travel outside Cartagena to other parts of Colombia?

Yes, in major areas of Cartagena, networks like **Tigo** and **WOM** provide 4G/LTE speeds that are more than sufficient for video calls, streaming, and other high-bandwidth activities.
