Sync SwissCenter contacts and calendar on iPhone (CardDAV, CalDAV)

Q: How do I sync the contacts (CardDAV)?

On your iPhone, open Settings > Apps > Contacts > Accounts. On an older version of iOS, the path is Settings > Contacts > Accounts. Select Add Account > Other > Add CardDAV Account. In the Server field, enter: mail01.swisscenter.com Enter your full email address as the username. Enter the mailbox password. Tap Next to validate. Your SwissCenter contacts then appear in the Contacts app on the iPhone.

Q: How do I sync the calendar (CalDAV)?

Open Settings > Apps > Calendar > Accounts. On an older version of iOS, the path is Settings > Calendar > Accounts. Select Add Account > Other > Add CalDAV Account. In the Server field, enter: mail01.swisscenter.com Enter your full email address as the username. Enter the mailbox password. Tap Next to validate. Your SwissCenter calendar then appears in the Calendar app on the iPhone.

To get the contacts and calendars of your SwissCenter email address on your iPhone, add the contacts with the CardDAV protocol and the calendar with the CalDAV protocol. These settings sync directly with the native Contacts and Calendar apps on the iPhone.

In short: in the iPhone Settings, add a CardDAV account (Contacts) and a CalDAV account (Calendar) with the server mail01.swisscenter.com, your full email address and the mailbox password; the WebDAV (calendars and contacts) service must be enabled.

Prerequisites

The WebDAV (calendars and contacts) service enabled for this address, in the address's Services tab (see Manage the services of an e-mail address (webmail, POP, IMAP, SMTP, WebDAV)).
A working Internet connection on the iPhone.
