Custer Telephone Cooperative, Inc. (CTCI), operating in the United States, provides mobile network services across segments of North America & the Caribbean. Utilizing Mobile Country Code (MCC) 312 and Mobile Network Code (MNC) 950, CTCI plays a role in connecting communities. While not as nationally ubiquitous as larger carriers like Verizon or AT&T, CTCI focuses on delivering cellular connectivity to specific areas. CTCI’s services are particularly relevant in regions where larger national carriers may face challenges in infrastructure deployment, or where a cooperative model better serves local connectivity needs. By broadcasting on 312 950, CTCI maintains its ability to offer key cellular features in compliance with national and international comms standards; these being SMS for communications, and data plans for those users who want to connect to the internet over their mobile devices. Understanding CTCI's MCC and MNC codes is essential for device compatibility and network selection when travelling or residing within their coverage footprint.
