Is public Wi-Fi safe in South America?

Public Wi-Fi in cafes and hotels is common but often insecure. Always use a VPN (like Mullvad or ExpressVPN) when connecting to public networks to protect your data.

Will one SIM card work for the whole continent?

No. While some 'regional' eSIMs exist, they are often more expensive and less reliable than individual country SIMs. Buy a fresh SIM or data plan for each country you visit.

Can I keep my WhatsApp number?

Yes. WhatsApp is tied to your account, not your SIM. When you swap SIMs, keep your original number in WhatsApp when prompted. Your messages and chats will remain synced.

Stay connected to the internet while traveling in South America

The most reliable and cost-effective way to stay connected is to buy a local prepaid SIM card upon arrival or use an eSIM app like Airalo for instant data coverage. Avoid relying on public Wi-Fi or international roaming plans from your home carrier, as they are often prohibitively expensive and throttled.

Check your phone's compatibility. Ensure your smartphone is carrier-unlocked. If it is locked to a provider in your home country, you will not be able to use a local SIM card.
Download an eSIM app. Download apps like Airalo or Nomad before you leave. These allow you to purchase data packages for specific countries (e.g., Brazil, Argentina, Chile) that activate the moment you land, avoiding the hassle of finding a physical store.
Buy a local physical SIM card. If you prefer physical SIMs, visit an official carrier store (like Claro, Movistar, or Tigo) in the airport or city center. Bring your passport, as most South American countries require it to register a prepaid SIM card.
Top up your data. Most carriers have apps or allow you to top up at local 'kioscos' or convenience stores. Use the carrier's USSD code (usually a sequence like *123#) to check your balance and remaining data.
