How to dial the number

In international format, a Brazilian number is +55 (Brazil’s country code), followed by the 2-digit area code (called DDD in Brazil) and the full number:

On the OiCall keypad, Brazil (+55) is already selected: just enter the area code and the number. On a computer, if you copied a number that already starts with +55, you can also paste it straight into the keypad. Don’t add a 0 or the carrier code that people use for long-distance calls inside Brazil. Check the digits before you call.

Who needs internet?

You need internet to call with OiCall (Wi-Fi or mobile data), and you need to allow the microphone in your browser or the app.

The person you call doesn’t need internet or an app. The call arrives as a regular phone call on their mobile or landline.
