Medellin Phone and SIM Card Guide — What to Buy When You Land

The moment you land at José María Córdova airport, one task should move to the top of your list: getting a working Colombian SIM card. Without it, Uber doesn’t work, WhatsApp doesn’t work (which is how everyone in Colombia communicates), and you’re entirely dependent on your accommodation’s WiFi for any navigation or communication. This guide tells you exactly what to buy, where to buy it, and what it costs.

Why You Need a Local SIM Immediately

Unlike some destinations where you can muddle through on WiFi for a day or two, Medellin’s essential services run on WhatsApp and data-dependent apps:

• Uber and InDriver: Both require a working phone number and data connection. Without a Colombian number, you can’t receive the SMS verification for new account setup or request rides reliably.
• WhatsApp: Your host, tour operators, restaurants (for reservations), and virtually every Colombian business communicates via WhatsApp rather than phone calls or email.
• Google Maps (real-time): While you can download offline maps for navigation, live data (traffic, updated routes) requires a connection.
• Translation apps: Real-time translation in markets, cafés, and conversations.

Getting a SIM at the airport — even at slightly elevated prices — is unambiguously worth it.

The Main Carriers in Colombia

Claro — The Recommended Choice

Claro is Colombia’s dominant carrier and the clear recommendation for most visitors. It has:
– The widest 4G/LTE coverage in Medellin and throughout Colombia
– Consistent data performance in both urban areas and day trip destinations
– Clear, well-staffed airport kiosks with English-speaking staff

Claro operates on the 1900 MHz and 850 MHz bands — compatible with virtually all modern unlocked smartphones from the US, Europe, and Australia.

Tigo — The Close Second

Tigo (owned by Millicom) is a solid alternative with competitive pricing. Coverage in Medellin’s main tourist areas is equivalent to Claro. Where Tigo lags is in rural coverage during day trips — the Guatapé reservoir area, parts of the Coffee Region, and some hillside neighborhoods above the city see weaker Tigo signal.

Movistar — Third Choice

Movistar (Telefónica) works but is generally considered the weakest of the three majors for coverage in and around Medellin. Not recommended as a primary choice unless there’s a specific price incentive.

WOM — Budget Option

WOM entered the Colombian market aggressively in recent years with very low prices and reasonable urban coverage. If you’re staying exclusively in El Poblado and Laureles, WOM works fine. For day trips or rural coverage, it lags behind Claro significantly.

Where to Buy Your SIM Card

At the Airport (Recommended for Immediate Activation)

Claro, Tigo, and Movistar all have kiosks inside the arrivals area of José María Córdova International Airport. They’re staffed, visible, and can activate your SIM immediately.

Prices are 15–30% higher at the airport than in the city. A plan that costs 50,000 COP in El Poblado might cost 65,000 COP at the airport. The premium is real, but so is the convenience of arriving with a working SIM rather than spending your first afternoon hunting for a carrier store.

What to bring: Your passport (required for registration). Your unlocked phone. Credit card or COP cash.

In El Poblado (Cheapest Prices)

If you’re arriving in the daytime and heading straight to El Poblado, carrier stores and authorized resellers are easy to find around Parque Lleras and the main commercial streets. Prices here are the standard (non-airport) rates.

The catch: you need to get from the airport to your accommodation using some form of transport before you have a working SIM. Options:
– Pre-booked private transfer (the host arranges, no SIM needed)
– Someone from your group already has a working SIM
– The airport WiFi is usually sufficient to request an Uber at the airport (a brief window of WiFi access is available)

In Malls and Supermarkets

Éxito and other major supermarkets throughout Medellin have carrier counters. Same prices as city stores, added convenience of combining with grocery shopping.

Tourist Data Plans — What to Buy

As of 2025, here are representative plan options (exact plans change — confirm current offerings at the carrier):

Claro Tourist Plans:
– 7 days / 5 GB data: ~25,000 COP (~$6 USD)
– 30 days / 15 GB data: ~55,000 COP (~$13 USD)
– 30 days / 30 GB data: ~80,000 COP (~$19 USD)

Tigo Tourist Plans:
– 30 days / 12 GB data: ~45,000 COP (~$11 USD)
– 30 days / 25 GB data: ~70,000 COP (~$17 USD)

For most visitors (1–2 week trip): The 7-day or 30-day 15 GB Claro plan covers typical usage — maps, WhatsApp, some streaming.

For digital nomads working remotely: The 30 GB plan is more appropriate. Video calls consume 500 MB–1 GB per hour depending on quality settings.

Is Your Phone Compatible?

Most modern smartphones from the past 4–5 years are compatible with Colombian networks. Key requirements:

• Unlocked phone: Your phone must be factory unlocked (or unlocked by your carrier). If you’re on a US carrier contract, check if your phone is internationally unlocked.
• SIM card size: Most phones now use nano-SIM. Bring an adapter if you have an older phone — airport kiosks typically have all sizes.
• eSIM: Some travelers prefer eSIM for convenience. Airalo offers Colombia eSIM plans from approximately $4–$12 USD for 7–30 day plans. The Airalo Claro or Tigo eSIM can be purchased before you land and activated on arrival. A good option if your phone supports eSIM and you want zero airport SIM-buying friction.

eSIM — The Modern Alternative

Airalo, Holafly, and Nomad all offer eSIM plans for Colombia. You purchase online, download a QR code, and scan it to activate — the physical SIM slot is freed for another purpose (useful if you want to keep your home number active on the physical SIM).

eSIM prices are roughly comparable to airport prices (more than city store rates, less than the very highest airport prices). The convenience of pre-configuration is worth it for many travelers.

eSIM plans for Colombia (typical ranges):
– 7 days / 5 GB: $8–$12 USD
– 30 days / 15 GB: $18–$25 USD

WhatsApp Setup — Do This First

Once your SIM is active:
1. Open WhatsApp on your phone
2. Register or switch to your Colombian number (+57 followed by 10-digit number)
3. Save your accommodation host’s WhatsApp number immediately
4. Save your Uber and transport contacts

Add the WhatsApp number for your accommodation within the first 15 minutes of having a working SIM. If anything goes wrong during your first night — lockouts, questions, recommendations — WhatsApp is how you reach your host at any hour.

Keeping Your Home Number Active

If you need your home number to remain active (for banking, 2FA, home-country contacts), there are a few approaches:

• Dual SIM phone: Keep your home SIM in slot 1, Colombian SIM in slot 2. Your home number stays active for calls and SMS; data routes through the Colombian SIM.
• WiFi calling: If your home carrier supports WiFi calling, you can receive calls on your home number over WiFi while using Colombian data.
• Google Voice or similar: Forward your home number to a VoIP service that works over data.

Most travelers find that putting their home number on airplane mode and using WhatsApp for all communication is sufficient — most home contacts can be reached that way, and banking 2FA apps typically have authenticator app options that don’t require SMS.
