i restored my data to a new phone. why am i missing some of my contacts?

Check that all of your contacts have a name and one of the following numbers - work, home, or mobile phone. Often a phone will not allow a contact to be entered if it does not have a name and one of those common phone number fields. To view your saved information, log into My Account, select Data Backup, and select the contact's name to view full contact details. To ensure proper functionality, copy/paste the phone numbers into a more common field (home, work, mobile). When you have completed the changes, click "Update Phone" or perform a manual backup from the application to send the changes to your phone.
