What is an eSIM, and how does it work in Brazil?
An eSIM (embedded SIM) is a small chip built directly into your smartphone, tablet, or laptop. Unlike a traditional SIM card, it isn't removable. Instead, it can be digitally programmed to connect to different mobile networks using downloadable profiles.
When you purchase an eSIM plan, the provider sends you a QR code or an in-app installation link. Scanning it securely loads the network profile onto your device. Once installed, the eSIM behaves exactly like a physical SIM. It connects your phone to local mobile networks for calls, messages, and data.
Most eSIMs for Brazil connect to local carriers such as Claro, TIM, and Vivo, providing 4G coverage across major cities like Rio de Janeiro, São Paulo, Brasília, and Salvador. The connection works through the same cellular infrastructure as local SIM cards, but setup is fully digital and can be completed in just a few minutes.
You can store multiple eSIM profiles on your device, though only one can be active at a time. This makes it easy to switch between providers or countries without changing cards or losing your number.
What's better for Brazil: an eSIM or a Brazilian SIM card?
For most travellers, an eSIM is the easier and more flexible option when visiting Brazil. It can be installed before departure, activated instantly on arrival, and used across major cities without switching physical cards or registering in person.
A Brazilian SIM card from operators like Claro, TIM, or Vivo requires an in-person purchase and passport registration with a CPF (Brazilian tax ID). While local SIMs may sometimes offer lower rates for very long-term residents, the setup process can be time-consuming for short-term visitors.
Choose an eSIM if you want:
✅ Instant setup before you fly
✅ Coverage across Brazil's major cities and regions
✅ No paperwork or in-store registration
✅ Easy plan management directly on your phone
Choose a local SIM card if you need:
✅ A physical number for local calls or SMS
✅ A long-term plan for several months or more
✅ Access to in-person store support for troubleshooting
For digital nomads, remote workers, and short-term visitors, eSIMs like Ubigi and Nomad provide the best mix of flexibility, reliability, and cost-efficiency in Brazil.

How to choose the right eSIM for Brazil
Choosing the best eSIM for Brazil depends on your travel plans, data usage, and how long you'll stay. Here are a few key points to consider before buying:
Check your data needs: If you mostly use maps, messaging apps, and browsing, a smaller data plan is usually enough. For video calls, remote work, or streaming, look for larger or unlimited plans.
Consider your trip length: Short trips or weekend getaways work well with smaller one-off data packages. For longer stays, monthly or flexible plans often offer better value.
Verify device compatibility: Most newer iPhones, Google Pixels, and Samsung Galaxy models support eSIM. You can check in your settings under Mobile Network → Add eSIM.
Review coverage by region: Brazil has good 4G coverage in major cities and popular tourist areas, but signal strength can vary in rural areas, the Amazon region, or remote parts of the Pantanal. Make sure your eSIM connects to major Brazilian networks like Claro, TIM, or Vivo for the best performance.
Look for support and setup help: Choose an eSIM provider with a clear installation guide, live chat, or refund option. This can be especially useful if you're switching phones or travelling between multiple cities.
Spending a few minutes comparing plans before your trip can help you avoid roaming fees, save on data, and stay connected wherever you go in Brazil.
How to set up your eSIM in Brazil
Setting up your eSIM for Brazil only takes a few minutes. Here's how to make sure everything works smoothly before and after you arrive:
1. Check device compatibility:
Make sure your phone supports eSIM. Most recent iPhones (XR and newer), Google Pixels, and Samsung Galaxy models do. You can confirm this in your settings under Mobile Network → Add eSIM.
2. Choose your data plan:
Pick a plan that matches your trip length and data needs. Short trips work well with small data bundles, while long stays are better suited to monthly or unlimited options.
3. Install the eSIM:
After purchase, you'll receive a QR code or an in-app installation option. Scan or follow the link to download the eSIM profile onto your device.
4. Activate on arrival:
Turn on your eSIM line and enable data roaming once you land in Brazil. Activation usually starts automatically when you connect to a local network.
5. Test your connection:
Open a map or browser to check that mobile data is working properly. If it doesn't connect right away, restart your phone or toggle airplane mode.
💡 Tip: Before installing a new eSIM, delete any old or expired eSIM profiles from your phone. This helps prevent setup errors and ensures a smoother activation process.
