|If you want to keep your contacts separate, then use the Google Voice website, which only sees your Google Contacts. An option in your phone contacts is to choose which account to show numbers from. You would need to switch back and forth between Phone contacts, and Google contacts when viewing each set of contacts. |
Google’s Contact Manager allows you to remove only 250 contacts at a time, which is the maximum number of contacts that you can select simultaneously. If your business contacts number in the thousands, you will need to take some time out of your day to delete the entire list. However, you can avoid deleting your contacts 250 at a time by using an older version of the Google Contact Manager. The older version enables you to select all of your contacts simultaneously for deletion. You can access the older version with your Google Account credentials.
