Calls that are not answered will be forwarded to your mailbox.
You will be informed by SMS when a caller has left a message. In Switzerland, you can check your voicemail at any time free of charge.
Abroad, the forwarding of calls to your mailbox will be charged like a call to Switzerland.
To avoid these charges, you have the options to deactivate your mailbox before traveling abroad:
Activate mailbox: *145# call key
Switch off mailbox: #145# Call key
