Where to buy a SIM card?

In Buenos Aires, buying a SIM card (called a chip in Argentina) is pretty straightforward, but it helps to know the best places and what to bring.

📍 Where to Buy a SIM Card in Buenos Aires #

1. At the Airport (Ezeiza – EZE & Aeroparque – AEP) #

• Personal usually has kiosks at Ezeiza (international airport).

• Convenient if you want data right away, but prices can be slightly higher.

• Limited to fewer options than in the city.

2. Official Carrier Stores #

• Claro, Personal, and Movistar all have official stores across BA.

• Buying here ensures your SIM is properly registered with your passport.

• Staff can help with setup, plans, and activation.

• Best option if you want reliability and clear pricing.

3. Kiosks & Convenience Stores #

• Many street kiosks (kioscos) and tech shops sell prepaid SIMs.

• Often cheaper and faster to buy, but:

  • They may not help with activation.

  • Registration might still require a visit to the carrier.

4. Online / eSIM #

• If your phone supports eSIM, you can buy digital packages from providers like Airalo, Holafly, or Claro Argentina eSIM.

• Avoids paperwork, but tends to be pricier.

🪪 What You Need #

• Passport (mandatory for registration).

• An unlocked phone.

• Cash or card (plans are cheap: ~USD $5–15 for a few GB of data).

✅ Quick Tips #

• Claro = best for nationwide coverage.

• Personal = best in Buenos Aires city, often easiest for tourists.

• Movistar = widely available but weaker network.

• Registration can take a few minutes — don’t leave the store until your SIM is working.
