Wi-Fi Calling offers you the following advantages:

• If you are calling in Switzerland, you benefit from excellent indoor coverage wherever you have Wi-Fi access.
• If you are calling or texting from abroad, you can avoid roaming costs: calls and SMS via Wi-Fi Calling are charged at the same tariff as within Switzerland.

More details here.

You can temporarily disable your voicemail – for example, if you travel and want to avoid roaming costs – by tapping ##002# or ##004# on your smartphone, then pressing the call button.

Note that callers will not be able to leave messages during this time, but you will get notifications by SMS to show who or which number has called you.

To reactivate it, tap **004*086xxxxxxxxxx# on your smartphone, then press the call button (xxxxxxxxxx is your mobile number. For example, if your number is 078 123 45 67, tap: **004*0860781234567#).

Your voicemail will work normally. When abroad, you may be charged for data usage when using your voicemail. To deactivate it, see FAQ "How do I deactivate my voicemail and reactivate it again?"

Visual Voicemail is only available to iPhone owners. It notifies you by SMS when a new voicemail message is received allowing you to manage it even more efficiently.

This service is free of charge in Switzerland. When abroad, roaming data charges apply, i.e.: 1 minute corresponds to approximately 100 KB (10 minutes correspond to approximately 1 MB). We therefore recommend that you temporarily deactivate your voicemail when travelling abroad.
