HiHello uses a CardDAV server to provide contacts to your address book. When you add HiHello contacts to your address book this way, you won’t need to give up any privacy to your current non-HiHello contacts. Sweet!
To receive HiHello contacts in this device’s address book, you’ll need to install HiHello as a profile by tapping “Set up address book” in-app. This allows us to set up your account more easily, without needing you to manually enter your account information.
Depending on your device’s operating system, your phone will either automatically download and install the profile, or it will download but require you to navigate to your Settings app to install.
You may be asked for permission to open settings and then install the profile.
After confirming installation, you’ll navigate back to the app. It may take a few minutes for your contacts to appear in your address book.
After downloading the profile, you may need to navigate to your Settings app to complete installation and receive contacts.
Head to your Settings app and tap General. Next, scroll down and open your Profiles. You’ll see “HiHello CardDAV Profile” as a downloaded but not installed profile. Tap the profile and complete installation.
After installation, it may take a few minutes for your contacts to appear in your address book.
