Why Castleford Chooses Anthem
The Internet Provider That Earns Your Business Every Month
Castleford's setting is shaped by one of the most powerful geological events in North American history. The lower canyon of Salmon Falls Creek just outside town — cut 300 to 600 feet deep into the Snake River Plain — was carved by the catastrophic Lake Bonneville Flood roughly 15,000 years ago, the same cataclysmic release of water that scoured the Snake River Canyon and sculpted the dramatic terrain that defines Magic Valley's landscape. Long before Twin Falls County existed, Castleford was already a recognized crossing point on the Kelton Road — the 232-mile freight route between Boise and Kelton, Utah that carried wagon teams and supplies through south-central Idaho in the decades before the railroad. The community was revitalized and reshaped during the early 1900s irrigation development period that transformed this part of Twin Falls County, and it sits today on the west bank of Salmon Falls Creek as one of the smaller but enduring agricultural communities in the Twin Falls Micropolitan Statistical Area. With a population of just over 200 in the city and primary employment in farming, fishing, and forestry occupations, Castleford is quintessential Magic Valley farming country — small, self-reliant, and deeply rooted in the land.
That agricultural character means connectivity matters in practical ways — farm operations, remote work, household needs — and the alternatives in Castleford have historically been limited to Sparklight, CenturyLink, and Rise Broadband without a locally invested provider stepping up. Anthem's Castleford tower delivers basic wireless service at speeds up to 100 Mbps, bringing a reliable, locally accountable option to a community that has been part of Anthem's Magic Valley home territory for years.

The Anthem managed router is included at no extra charge and works well for residential and small business use, but farm operations that need specific network configurations for ag technology equipment are fully supported in using their own equipment. Call 208-677-8000 before your install to discuss your setup.
Anthem's fixed wireless installation is straightforward and typically completed in one visit. A certified Anthem technician installs a small radio on the exterior of your home or building, pointed toward the nearest Anthem tower. The technician then routes a cable from the radio inside your home to either an Anthem managed router, which is included with your plan, or your own router if you prefer to use your existing equipment. The managed router provides built-in Wi-Fi and gives you access to Anthem's parental controls and network management tools from your phone. Most installations are completed in under two hours.
