Clearwire and Simplexity MVNO Services Announce New Wholesale and MVNE Agreement

Reston, VA and Bellevue, WA – January 23, 2012 – Clearwire Corporation (NASDAQ: CLWR), a leading provider of 4G wireless broadband services in the U.S. and Simplexity MVNO Services, a fully integrated Mobile Virtual Network Enabler (MVNE), today announced the formation of a strategic wholesale relationship whereby Simplexity will become an authorized reseller of Clearwire’s 4G mobile broadband service, Clearwire’s preferred MVNE and Clearwire’s preferred provider for Third-party Branded Services. Commercial service is slated to be available later this year.

As Clearwire’s preferred provider of Third-party Branded Services, Simplexity will become a wholesale customer on Clearwire’s 4G network for the purpose of offering private-branded mobile broadband services. Simplexity’s MVNO support services will allow organizations to offer their customers private branded and customized wireless plans with a turnkey approach that reduces time to market, effort and cost needed to reach the more than 130 million potential customers covered by the Clearwire 4G network. By leveraging Simplexity’s customizable MVNO platform, its partners can realize the benefits of having unique wireless offers and rate plans without the need to become an MVNO.

Furthermore, Simplexity will become Clearwire’s preferred MVNE and an authorized reseller in support of Clearwire’s growing 4G wholesale business. Under the agreement,Simplexity will deliver its comprehensive services platform to the wide range of existing Clearwire MVNOs to enable rapid deployment and ongoing management of their wireless programs. A Clearwire MVNO has the flexibility of choosing between Simplexity’s end-to-end turnkey solution and a customized solution tailored to their specific needs. In either case, Simplexity’s extensive industry experience provides the expertise, while its scale and proven systems provide the cost savings, both of which are critical for an MVNO to succeed.

Simplexity’s services include sales and order acquisition, activation and provisioning, distribution and logistics, billing and subscriber lifecycle management, customer care and management analytics. Simplexity currently provides services for national retailers, online retailers, telecommunications providers, OEMs, direct marketing organizations and affinity groups.

“We are very excited about our agreement with Clearwire. Their proven 4G track record, deep spectrum portfolio and broad portfolio of existing and potential MVNO partners creates a tremendous opportunity to expand our offerings to a wide range of current and potential 4G wholesale customers,” said Terry Hsu, president of Simplexity MVNO Services. “By allowing our partners the choice to become a direct wholesale customer of Clearwire or to leverage our customizable private branded platform, Simplexity will make it easy for any organization to offer Clearwire’s 4G service to its customers. With the rapidly growing demand for mobile broadband service, now is the perfect time for companies to create incremental revenue opportunities and cultivate customer loyalty with branded wireless service offerings.”

“The reach and unparalleled scalability of Clearwire’s 4G mobile broadband network offers a very competitive platform to carriers and businesses across a wide range of industries seeking to grow rapidly in an increasingly mobile-centric world,” said Don Stroberg, president of strategic partnerships and wholesale at Clearwire. “Simplexity’s ability to offer MVNE services adds a new level of choice and flexibility that will make it even easier for potential wholesale partners seeking a simple back office solution to support their 4G product offerings.”

Simplexity 4G Experience

The 4G customer experience using Clearwire's mobile broadband network will be similar to Wi-Fi but without the short-range limitations. Clearwire's network uses a wireless 4G technology that differs from Wi-Fi because it provides service areas measured in miles, not feet. Simplexity’s 4G service will offer average mobile download speeds of 3 to 6 mbps, with bursts over 10 mbps*, using the Clearwire network. Clearwire's 4G network is currently available in more than 70 cities across the U.S. where approximately 133 million people live.
