# T-Mobile 2G network shutdown in the United States > Live situation record from CLSTR: https://clstr.news/situations/t-mobile-2g-network-shutdown-in-the-united-states > Updated: 2026-08-11T02:21:27.000Z. Sources: 18. Developments: 2. T-Mobile has decommissioned its 2G GSM network, marking the end of 2G service across all three major U.S. carriers. Following the earlier retirements of 2G services by AT&T in 2017 and Verizon in 2020, this shutdown removes the final cellular connection option for the original 2007 iPhone in the United States. The transition is driven by the need to reallocate spectrum to more efficient technologies like 4G LTE and 5G, alongside security concerns regarding older GSM encryption standards. Beyond mobile phones, the shutdown affects legacy equipment such as payment terminals, alarm panels, and other IoT devices. For collectors, the original iPhone now functions primarily as an “offline historical artifact.” This technological transition continues to impact device longevity and market dynamics. As the industry-wide shift toward 4G and 5G technologies solidifies, the obsolescence of original iPhone models for communication is finalized, reinforcing their status as collector's items. ## Timeline ### 2026-08-11: Smartphone market sees iPhone price drops and 2G network shifts Smartphone trends show significant price drops for older iPhone models in Vietnam, while the US 2G network shutdown renders original iPhones obsolete.
