Brazilian bank app abroad: why it stops working and what to do
FortiSafe team ·
In most cases, a Brazilian bank app works outside Brazil. When it fails, it's usually for one of three reasons: the bank blocks access from other countries, confirmation depends on an SMS to a Brazilian number, or the phone isn't registered with the bank. A VPN with a Brazilian IP only fixes the first one.
The three reasons, and what fixes each one
| Reason | What the official source says | What fixes it |
|---|---|---|
| The bank blocks access from another country | Caixa says some of its apps may not work outside Brazil, to protect customers from attacks. | A connection with a Brazilian IP, such as a VPN with a server in Brazil. |
| SMS confirmation to a Brazilian number | Inter doesn't accept foreign phone numbers and tells customers abroad to turn on roaming on their Brazilian SIM. | Keep your Brazilian SIM with roaming on. A VPN doesn't fix this. |
| Phone not registered with the bank | Under Brazil's Central Bank rules, Pix from an unregistered device is capped at R$ 200 per transaction and R$ 1,000 per day. | Register the phone you'll use with your bank before you travel. A VPN doesn't fix this. |
What a VPN doesn't fix
- SMS and SIM: the confirmation code goes to your Brazilian number, wherever you are.
- A new or unregistered phone: the Pix rule looks at the device, not the country the connection comes from.
- If you've moved abroad: for that case, Caixa suggests a power of attorney at the consulate so someone can operate the account in Brazil.
Our test
Test run by the FortiSafe team on 13 September 2026, in Paraguay, on an iPhone 17 Pro Max, using the WireGuard app connected to the br1.vpn.fortisafe.net server in São Paulo. The FortiSafe app is still in development.

The apps opened, the team signed in to the accounts and made transactions in some of them, with no failures or extra verification.
This is the result of one device, in one country, on one date. Any service can change how it behaves at any time.
Before you travel
- Register with your bank the phone you'll use outside Brazil.
- Turn on roaming on your Brazilian SIM, or confirm with the bank another way to receive the confirmation code.
- Update the app before you leave: Inter asks customers not to update or reinstall the app while travelling.
- If you'll use your card abroad, tell your bank: Bradesco asks for your destination and travel dates.
- Check whether your bank restricts access from your destination: Inter lists six countries where access is blocked.
