I can't find the contacts button on my iPhone
If you can't locate the contacts button (seen left), there's a chance that the Contacts app may have been deleted from your iPhone.
Every iPhone comes with a Contacts app, but it is deletable. In order to download a pre-filled contact card, such as any Aerogami Contact Point contact card, you'll need to have the Contacts app on your iPhone.
To re-download the Contacts app: you can go to the App Store and search "Contacts." It should be the first app that appears; it will be labeled as a utility. After you download it, you should be able to go through the whole contact card download process successfully.
