If you’re using Android devices, there’s a good chance that you have the AT&T Address Book installed. This is a great tool for keeping track of your contacts and calendar events, and it can be very helpful when trying to connect with people who are in other countries. However, if you want to disable the Address Book on your Android device, there are a few steps you can take. First, open the Settings app and select “Address Book.” Then, under “Usage,” select “Disable.” Finally, make sure that “AT&T Address Book” is checked in the “Addresses” section of the app’s preferences. This will disable the Address Book on your device completely.
