You can also send personal, person-to-person texts to numbers outside the US — though delivery depends on the receiving carrier accepting texts from US numbers. Texting US numbers is coming soon and will run as A2P, the registered route US carriers require (that's also the path business texting will use).

Some background on South Dakota and its area codes

South Dakota is served primarily by area code 605, which was established in 1947 as one of the original North American area codes. It covers the entire state, which reflects South Dakota's relatively low population density and demand for telephone numbers. The area code has remained unchanged since its inception.

The 605 area code provides service to major cities such as Sioux Falls, Rapid City, and Pierre, the state capital. Despite the increasing use of cell phones and other telecommunications services, 605 has sufficed due to South Dakota's stable population growth and efficient number allocation practices, avoiding the need for additional area codes.

In 2021, the Federal Communications Commission mandated the transition to ten-digit dialing in the 605 area due to the nationwide implementation of the 988 National Suicide Prevention Lifeline. This change increased the complexity of dialing within the area, but it ensured the continuity of the existing numbering plan without requiring a new area code.
