Conference Calling allows you to establish calls with three to five other people at the same time, depending on your wireless phone's technology. Note: This feature is not available on all wireless devices. Refer to your wireless phone's User Manual to determine if your device supports this feature.
Call Forwarding lets you forward your incoming wireless calls to another phone number. With Call Forwarding activated, you can continue to make outgoing calls from your wireless device. Forwarded calls are billed airtime from the time the call is answered until it is ended. Each call forwarded may receive, depending on your location, per-minute/per-call charges based on where the call is forwarded. Long distance charges apply if the call is forwarded to a long distance number.
Caller ID (or Caller Identification) lets you know who's calling before you answer by displaying the caller's phone number on your phone's display. Caller ID is included automatically with all AT&T wireless rate plans.
Call Waiting lets you receive an incoming call when you're already engaged in a conversation on your wireless phone. After a notification, you can put the first call on hold and answer the second call. You can also decide not to accept the second call and route it to voicemail. You will incur airtime and any applicable long distance and roaming charges for both calls simultaneously.
Unlimited Mobile to Mobile Calling allows you to make unlimited calls to and from any other AT&T wireless customer when making calls within your rate plan's calling area. Mobile to Mobile only applies to calls made and received while in the U.S., Puerto Rico, and the U.S. Virgin Islands.
