Colombia SIM Card Guide | Claro vs Tigo Speed & Coverage Challenge

Last personally verified: July 2026

Ditch the $10-a-day US carrier ripoff and embrace the ultimate frugal travel hack for your next Latin American adventure: the local SIM card.

Quick Answer: Which SIM is Best?

During my three months traveling overland from the dusty roads of Bucaramanga up to the Caribbean heat of Santa Marta, I tested these mobile networks daily. If you are paying $300 a month for Verizon or AT&T's international roaming, you are bleeding travel funds. As a frugal traveler stretching every dollar, I netted 80 gigabytes of data for a full month in Colombia for just $7.50 USD.

Digital nomad hubs like Medellín are flooded with ads for travel eSIMs like Airalo and Holafly. While an eSIM offers undeniable convenience—you install it before you even land at the airport—it comes at a steep premium. A typical 5GB Colombia data plan on an international eSIM will run you around $16 USD. Holafly offers unlimited data for about $53 USD for 15 days.

Compare that to a local physical SIM card: roughly $7.50 USD (about 30,000 COP) gets you a staggering 80GB of data on Claro's prepaid network for 30 days. If you are serious about traveling Colombia on a budget, the physical SIM card is the undisputed winner. eSIMs are a backup plan; local chips are the standard.

To get definitive data, I ran a direct experiment on a long-haul bus ride. After dropping 92 mil COP for a ticket, I hit the road. Armed with a burner phone and my main device, I pitted Claro against Tigo across the Andes and the Caribbean coast.

Geographic Coverage Breakdown

Major Cities (Bogotá, Medellín, Cali): Tigo offers blazing speeds (you can review their official coverage map at Tigo Colombia). If you are staying put in urban environments, Tigo handles heavy video streaming and remote work flawlessly.

The Andes & Rural Routes: As the bus rolled through the humid, rural mountains toward the coast, Claro proved superior. In remote spots where Tigo dropped the signal entirely, Claro kept me firmly connected to the grid. If you plan to head south toward the Rumichaca border via Pasto, cross-reference this with my Ecuador SIM Guide.

Step 1: The Initial Purchase (Bring Your Passport)

Foreign tourists cannot buy a functional SIM card off a random street cart. Under regulations by the Colombian CRC, you must visit an official Tigo or Claro storefront and present your physical passport to register your device's IMEI and activate the chip. For about $1.50 USD (6,000 COP), you get a new SIM with a starter pack of 2GB of data and 3 days of service to get rolling.

Step 2: The Tienda Recharge

To extend your service for the month, skip the official stores and head to an Oxxo, SuperGIROS, or a local mom-and-pop tienda. Use my cheat sheet below to verbally recharge your phone (a "recarga").

Can foreigners buy a SIM card in Colombia?

Yes. Foreigners can purchase a local SIM card, but you must bring your original physical passport to an official provider store (like a Claro or Tigo office) to register the IMEI of your phone and activate the chip.

Does Colombia require IMEI registration?

Yes. To combat phone theft, the government requires all mobile devices using a local network to be registered. When you buy your SIM at an official store, the agent will link your phone's unique IMEI number to your passport.

Can I buy a SIM at Bogotá airport?

You can, but it is typically more expensive. Look for official provider kiosks if possible, but avoid third-party electronics stores in the terminal that charge a massive premium to tourists. If you can wait until you get to the city center, you will save money.

Can I use an unlocked phone?

Yes, your phone must be physically and digitally unlocked by your home carrier to accept and operate with a foreign SIM card.

Does Claro have 5G in Colombia?

Yes, Claro rolled out 5G networks in major Colombian cities including Bogotá, Medellín, Cali, and Barranquilla. However, in rural mountain towns, expect standard 4G/LTE.

Can I keep my WhatsApp number?

Absolutely. When you insert a new Colombian SIM card, WhatsApp will ask if you want to update your phone number. Select "Keep current number" to retain all your chats and contacts tied to your home country's number.

Can I recharge online?

Yes, through the Claro or Tigo mobile apps. However, these apps sometimes struggle processing foreign credit cards. Recharging with cash at a local tienda is often the easiest and most reliable method for tourists.

Can I use my Colombian data as a mobile hotspot?

Yes. Both Claro and Tigo prepaid plans allow you to tether and use your phone as a mobile hotspot, which is crucial for remote workers needing reliable internet on their laptops.

Which SIM works near the Ecuador border?

Claro is the definitive winner in the deep southern regions. If you are traveling through Pasto or crossing the border at Ipiales, Tigo signals will heavily degrade while Claro maintains a stable 4G connection.

If you are backpacking across Colombia, riding long buses between remote towns, or climbing El Peñol in Guatapé, choose Claro for its unmatched rural reliability.

If your itinerary consists strictly of staying in digital nomad hubs like El Poblado in Medellín or Chapinero in Bogotá, Tigo's urban speed may make it the better option. Either way, bypass the expensive tourist eSIMs and stick to the local physical chips to keep your budget intact.
