[Home](https://allaboutbuenosaires.com) | [Docs](https://allaboutbuenosaires.com/docs/) | [Practical Tips](https://allaboutbuenosaires.com/docs-category/practical-tips/)

In **Buenos Aires**, buying a SIM card ([called a *chip* in Argentina](https://www.argentina.travel/en/news/how-to-get-internet-in-argentina-a-guide-for-foreign-tourists-and-digital-nomads#:~:text=Argentina%20has%20three%20main%20mobile,digital%20eSIMs%20for%20compatible%20devices.)) 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](https://allaboutbuenosaires.com/docs/do-i-need-cash-or-can-i-pay-by-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](https://allaboutbuenosaires.com/best-places-to-stay-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.
