"IMPORTANT NOTICE REGARDING SUNROCKET

After significant effort by the Company to avoid this result, SunRocket is in the process of discontinuing its operations as you know it. Therefore SunRocket will no longer be able to provide its customers with the phone service that its customers have been accustomed to.

However, two service providers are assisting and offering to provide SunRocket customers the opportunity to sign up for their services. Both providers have agreed to become preferred providers with special pricing for the SunRocket customers to enable them to migrate their telephone service. Of course, there are other providers and each individual customer can make their own decision as to which carrier they wish to transition to.

Emails to the SunRocket customers are currently being sent with more detailed information on how to sign up with the two service providers. The email address of the SunRocket customers that is on record is the address being used to send emails to the customers.
