Yes, whether you're in Italy, Brazil, or the U.S. - with our Voice Option, you're always connected, even when you're abroad.
You can also make calls/SMS from Switzerland to another country with the Voice Roaming Option.
First, you have to open the detail view in the cockpit for the right SIM card.
This is how it works: Where can I view/change the SIM details?
Then activate the field "International calls / Roaming" in the detail information of your SIM card to be able to make incoming and outgoing calls and SMS to and from abroad.
Note that no separate roaming data package is required for using the voice option abroad. Charges are only incurred for services actually used abroad.
You can find more information about the costs here: How much does voice roaming and value added services cost?
