What is AT&T shutting down?

AT&T is shutting down its 3G networks as part of a greater effort to re-use the spectrum for 4G and 5G — newer standards that are more efficient than 3G. T-Mobile (TMUS) will do the same in the third quarter and Verizon (VZ) will do so by the end of the year.22 Şub 2022
