See who is calling you before you answer.
Call Display shows the phone numbers of your incoming calls so you can choose whether to answer the call. When used with Call Waiting, you see incoming phone numbers even if you are on another call.
Using outbound Call Display, also called caller ID, you determine whether your number displays to the people you call. When you block your number, it displays as "Restricted."
Call Display is available as part of a phone package or on its own for $7/month. It is included with prepaid service and Mike plans.
