Does the person Im calling need to have Clearwire Digital Voice service too?
No. You’ll be able to use Clearwire Digital Voice Service to make and receive calls just as you would with your regular phone service* regardless of what type of phone service the person you are calling has. *Note: At this time Clearwire Digital Voice Service does not support incoming collect calls, and outgoing 976, 900, 10-10 dial around, or N11 calls.
