I still remember the days when traveling meant struggling to stay connected. Back in 2003, while studying English in London, I would spend hours in internet cafes just to call my family in Colombia—international calls were expensive, and tools like WhatsApp hadn’t yet arrived. Even as late as 2023, during trips to the US and Europe, my limited tech skills made communication a real challenge. Fast forward to today, and the internet has transformed our lives. Affordable SIM cards and unlimited plans now ensure that staying in touch is effortless. Let’s dive into my opinion as a local Colombian on the best and cheapest options to buy a SIM card—whether it’s Claro, Tigo, or Movistar.
Best SIM Card Providers in Medellín: Tigo vs. Claro vs. Movistar
When it comes to mobile connectivity, Medellín offers a variety of options. Here’s how the top providers compare in 2025:
- Tigo: In my experience, Tigo can be somewhat limited when traveling to areas such as Oriente, Guatapé, and Guarne, the airport etc. I often encountered signal drops and difficulties receiving calls or using data in these regions.
- Claro: For me, Claro is the best option. After switching to Claro, my connectivity issues were resolved—even when traveling frequently to Oriente. The signal remains strong, and the internet data is consistently reliable. Continue reading to discover a hack that reveals the best way to buy your SIM card.
- Movistar: Movistar’s performance is quite similar to Tigo’s, with comparable limitations in signal and data reliability, especially in the same regional areas.
5G: The Next Generation of Connectivity
Understanding local network performance is crucial. Here’s a quick guide to which provider works best where:
- Medellín and main cities in Colombia are beginning to roll out 5G networks that enhance streaming, video calls, and overall digital experiences. While still expanding to other local regions, 5G promises a more robust and reliable connection—perfect for digital nomads and travelers who rely on high-speed internet for work and leisure.
Where to Buy a SIM Card: Airport vs. City Center and “Barrios” (2025 Tips)
Deciding where to purchase your SIM card can impact your initial connectivity and convenience. Here are your two main options:
José María Córdova Airport SIM Card Kiosks: Updated Locations & Pricing
At José María Córdova Airport, several kiosks offer SIM cards with immediate activation, ensuring you’re connected as soon as you land. However, before committing keep in mind that some kiosks may ask for your passport or ID, or try to enroll you in a postpaid plan—which, in my opinion, isn’t ideal if you’re staying in the country short term.
City Center Options
Purchasing a SIM card in the city center works similarly to the airport option. Agents here may ask for your passport or ID and could try to enroll you in a postpaid plan. They might also offer you a “plan prepago,” which is a good option, though it usually requires providing all your personal details.
Comparison of SIM Card Purchasing Options
| Option | Location | Documentation | Notes | Rating |
|---|---|---|---|---|
| Barrio Options | Belén, La 70, Buenos Aires, etc. | None | Prepaid SIM, < $1 USD, quick & simple | 🟢 Best |
| City Center | Various spots in Medellín | May require passport/ID | Offers postpaid & prepago; needs personal details | 🟠 Average |
| Airport Kiosks | José María Córdova Airport | May require passport/ID | Immediate activation; pricier, often pushes postpaid | 🔴 Poor |
eSIM Option
To be honest, I have not explored the eSIMs as an alternative to physical SIM cards in Colombia, But If you need connectivity upon arrival. Essentially, an eSIM might work, it is like a virtual SIM card that’s activated through an app. The good thing is you end up having like two SIM cards running simultaneously on your phone.
Why I Switched to Prepaid Plans in Colombia
I used to buy postpaid plans, but before one of my trips to Florida, I had to cancel mine. It was a real headache—operators put up endless obstacles to prevent you from canceling. After finally managing to cancel it, I decided to switch to prepaid. Now, I use Claro on a prepaid plan, paying only $31,000 COP for 90GB of data and unlimited national calls, and it works perfectly for me.
Language Barrier Solutions
For many non-Spanish speakers, purchasing a SIM card in Medellín may present a language challenge. Here are two practical solutions:
Google Translate Offline:
Use Google Translate with the phrase:
“Necesito una SIM prepago, por favor”
which translates to “I need a prepaid SIM.”Bilingual Stores:
Look for providers that offer English support. For instance, the Claro store in Santafé Mall (El Poblado) has bilingual staff ready to assist international travelers.

Q: Can I buy a SIM card at José María Córdova Airport?

A: all major providers offer 5G. However, for me Claro is known for its strong signal.
