Connectivity That Matters!

Celerity Networks has completed the expansion of Internet Service to Belle Fouche and St. Onge South Dakota. Our new tower in downtown Bell Fourche gives us great coverage in and around town. In addition to this site we have added two additional sites close to St. Onge, SD giving us coverage in this area as well. With the addition of these sites Celerity Networks can now deliver high speed internet service to Spearfish, SD, Saint Onge, SD, Belle Fourche, SD and Beulah, WY.

Celerity continues to expand our services to locations not currently served by existing broadband service providers.

​​“Before Celerity provided Internet services to Ranch A, all we could get was dial up and satellite internet. Neither was adequate for 30 college students and our guests.
Celerity provided the expertise to solve our extraordinary needs, obtained and installed the equipment to do so. They were honest, responsive and worked with us to find an economical solution to get high speed Internet to Ranch A. The staff, students and guests have been extremely satisfied with Celerity. They deliver the high speed internet they promised.
We recommend Celerity to anyone that wants service that goes above and beyond.”
