Do you make regular calls abroad from Switzerland? The International Calls option lets you make unlimited calls.

Roaming costs near the border

If you stay near the Swiss border you mobile phone may automatically switch to a foreign mobile phone network. This can also happen some distance from the border, in the Lake Geneva area or in mountain regions (such as Jura, Alpstein, Grisons or Valais Alps). Since much lower radiation limits apply in Switzerland than in the EU, EU networks extend much further into Switzerland than vice versa. To avoid roaming costs, we recommend that you switch off the automatic network selection on your mobile phone.
