Adding a Contactzilla address book on your iPhone: Using the provisioning Profile

When you create a CardDAV connection in Contactzilla, you have the option to download a provisioning profile (a .mobileconfig file) that contains all the necessary connection settings for your device. This profile makes it easy to set up your iPhone to sync with Contactzilla by simply installing the profile on the device instead of manually entering server details, usernames, and passwords. It takes a matter of seconds!

Downloading the provisioning profile

1) From your CardDAV connections list in Contactzilla, find the connection you want to use and click ‘Download profile’. This will download a .mobileconfig file which we will open on your iphone.

The CardDAV provisioning profile is shown in the CardDAV connections area of your Contactzilla dashboard.

Installing the Profile on Your iPhone

1) After downloading the profile, send it to your iPhone via email, AirDrop, or your preferred method.

2) Go to Settings on your iPhone (you’ll need to navigate to the main Settings screen) and look for ‘Profile Downloaded’ near the top of the Settings menu > Ignore the ‘The profile is not signed’ message and press Install

What Happens After Installation

Once installed, the profile:

  • Sets up the CardDAV connection with your Contactzilla address book
  • Configures all necessary server details
  • Adds your contacts to the native iPhone Contacts app
  • Creates lists/groups based on your Contactzilla labels
After installation all the contacts from your Contactzilla address book show up in the native contacts app.

Note: For MDM deployments, IT administrators can push these profiles directly to devices without manual installation.
