Verizon decommissioned its 3G network on December 31, the last major US carrier to do so after AT&T and T-Mobile turned off services earlier in 2022
It's well and truly curtains for 3G, one of the key technologies that helped usher in the age of the smartphone.
Context & Ripple Effects
Verizon had repeatedly postponed its 3G retirement, including an indefinite delay announced after earlier shutdown targets slipped. AT&T and T-Mobile then ended their own 3G services earlier in 2022, leaving Verizon as the final major US carrier still operating the older network.
Verizon's cutoff removes that last exception, completing a transition that had been staggered across the three national carriers.
First-order effects
- Verizon customers and devices still dependent on its 3G service lose that network option as the carrier completes its shutdown.
- AT&T, T-Mobile, and Verizon now share the same baseline: none of the major US carriers continues to operate 3G service.
Second-order effects
- The end of Verizon's remaining 3G service removes a source of network-technology divergence among the major carriers, so customers with legacy 3G-dependent devices no longer have a national-carrier alternative.
- Verizon's years of delays had prolonged the transition relative to AT&T and T-Mobile; the completed cutoff closes that gap.
Third-order effects
- The completed shutdowns mark the retirement of a smartphone-era network layer across the major US carrier market, concentrating compatibility around newer cellular generations.
- If carriers continue to retire older network layers in coordinated succession, device and service support will be shaped less by any single carrier's timetable and more by an industry-wide transition cycle.
The trend: Major US carriers are converging on newer network generations as the final holdouts retire legacy cellular service.
