How do I transfer my Android contacts to my iPhone?

First, verify that your Android contacts are stored in your Google account. To do so, visit https://contacts.google.com.

If your contacts are in fact in Google, you add them to your iPhone by going to your iPhone Settings > Apps > Contacts > Contacts Accounts > Add Account.

If you wish to sync Google with iCloud, you can do so as follows:

1. Open the Contacts Sync app, and go to Accounts. Sign into your Google account.
2. Go to Contacts Sync > Accounts > iPhone Account to Sync, and choose iCloud
3. Go to Contacts Sync > Sync > 2-Way Sync
