Nobody knows phone service quite like ITC. We've been providing phone service to South Dakota and Minnesota for almost 60 years. We've learned a few lessons from our customers along the way — about providing the best quality service with a personal touch and helping customers get the services they need at an affordable price.

In addition to providing the highest quality digital phone, unlimited local calling, and long distance service, ITC offers a wide range of affordable calling features from Caller ID and Voice Mail, to features that screen telemarketers or allow you to forward your home phone calls to your wireless phone.


Lifeline is a federal program that provides a monthly discount on telephone service to qualified low-income residents. Lifeline is designed to ensure that telephone service remains affordable to all residents.
