Using iTunes:

With the help of iTunes you can sync the contacts stored on your iPhone with a Google account. Once this step is complete, you can then re-sync the contacts stored on the account, with your ZTE Concord II. For this method you need access to a computer with Internet and iTunes installed.

  1. Open iTunes on your computer
  2. Establish a USB connection between your iPhone and computer
  3. From iTunes, click the iPhone to reveal its summary page
  4. Go to the "Info" tab and mark the check box next to "Sync Contacts With"
  5. Select "Google Contacts" from the drop-down menu
  6. Register your Google account, or otherwise, if you've already done so before, you can click "Configure" and select an existing account from the list
  7. To commence the syncing process, click "Apply"
  8. On the ZTE Concord II, sign in with the same Google account (NOTE: to add an account, go to "Settings" > "Accounts")
  9. Allow the Google account to sync contacts with your Android phone

Using iCloud:

In case you've used the iCloud backup service before, then your iPhone contacts are most likely already stored on your iCloud account. By accessing it using a computer hooked up to the Internet, you can export these contacts as a VCF file for use on the Android smartphone.

  1. Launch the Internet browser on your computer
  2. Visit and sign in to iCloud
  3. Click "Contacts" and choose the contacts you wish to transfer
  4. Click the cog-wheel icon located in the lower left area
  5. Select to "Export vCard" and wait for the VCF file to be downloaded on the PC
  6. Import the vCard file to "Google Contacts". Alternatively, connect the ZTE Concord II to your computer via USB, and copy the VCF file to the phone's storage. Then, open the "Contacts" app and from the "All Contacts" tab, press "Menu" > "Import / Export" > "Import from storage". Choose an account and select the vCard file to load it

Using "My Contacts Backup":

Another way to transfer contacts from an iPhone is with the help of third party applications. My Contacts Backup is an iOS app that can be used to back up all of your iPhone contacts in the form of a VCF file, which can then be transferred to the Android device via email.

  1. Go to the App Store and install "My Contacts Backup" on your iPhone
  2. Open the application and then tap "Backup". All of the contacts will be compiled in a vCard file
  3. Tap "Email" and compose a new email with the VCF file attached to it
  4. Send the email to your Gmail address
  5. On the ZTE Concord II, open the email and download the attached file
  6. Once downloaded, import the file via the "Contacts" application, using the "Import" option from the app's "Menu" (as detailed at the end of the iCloud guide)

Using "Send Anywhere":

Last but not least, you can use "Send Anywhere" to transfer your contacts without needing a computer. Send Anywhere is a third party iOS and Android app that can transfer contacts and other types of files cross platform, for one smartphone to another via a P2P connection. To do so:

  1. Go to the Google Play Store and install "Send Anywhere" on the ZTE Concord II
  2. From the App Store, install the app on the iPhone as well
  3. Open the application on both smartphones
  4. From the iPhone, tap "Send" > "Contacts"
  5. Select the contacts you wish to transfer and tap "Send"
  6. Finally, choose the desired sharing method. You can tap "Receive" on the ZTE Concord II and enter the randomly generated transfer code from the iPhone. Otherwise, you can tap "Generate QR Code" on the iPhone and scan the code with the Concord II's camera to begin the transfer
