Qwest Communications International Inc. (NYSE: Q) and Verizon Wireless announced today they have signed a 5-year agreement for Qwest to market and sell Verizon Wireless service beginning this summer. Financial terms of the agreement are not being disclosed.

Under the agreement, Qwest customers will have access to the full line of Verizon Wireless handsets, smartphones and BlackBerry devices. Residential customers will be able to choose “wireless only” and be billed directly by Verizon Wireless, or include Verizon Wireless service as part of a Qwest bundle with their home phone, Internet and video services, and receive one bill from Qwest for all services.

In addition, the companies will work together on bidding for enterprise and government wireless contracts, and collaborate in the development of converged services, such as a unified voicemail box for mobile and landline as well as integration of Qwest’s IP networking solutions with Verizon Wireless’ mobile data network for business and government customers.
