AT&T Shuts Down 
Its 3G Network.
CNN reports AT&T will shut down 
its 3G network on Feb. 22.
The technology, which was 
implemented 20 years ago in the 
U.S., will come to an end in order 
to repurpose the spectrum 
for 4G and 5G.
AT&T says it has advised 
customers for two years to 
make the switch from 3G.
For nearly two years, we’ve proactively sent numerous communications via direct mail, bill messaging, emails and text messages to help customers transition to next generation networks before 3G services end on February 22, AT&T, to CNN Business.
Other major carriers will 
follow suit later this year.
CNN reports T-Mobile will ends its 3G network in the third quarter, and Verizon will do the same by the end of the year.
