To avoid service discontinuation, it's time to migrate your 2G IoT devices as soon as possible.

Countdown to planned 2G shutdown date:  Only

In order to keep up with exploding demand for mobile broadband data, AT&T announced plans in August of 2012 to sunset its 2G network by approximately January 1, 2017. This will allow AT&T to free up spectrum for added capacity to our advanced wireless networks, enabling more AT&T customers to have a better experience. For our IoT customers specifically, our advanced networks enable the delivery of more enhanced applications and solutions that benefit your customers and employees.


This page will help answer your questions about transitioning to a faster, higher capacity network. It also provides information, tools and resources to help you design and implement a transition plan for your business.

Why network migration is necessary

Migrating to faster, higher-capacity networks will help us ensure that we're using our available bandwidth as efficiently as possible to serve all our customers. Our data traffic has grown at a staggering rate since 2007, and will continue to increase dramatically in the foreseeable future.

The higher speeds of the upgraded network will enable our IoT customers to deliver enhanced applications and solutions, which will benefit their customers and employees. For example, our advanced networks will support video cameras for real-time streaming and driver dash cameras for fleet trucks. These enhancements would not be possible on the 2G network.

Transition Timing

AT&T has announced plans to sunset its 2G network by approximately January 1, 2017. As AT&T progressively frees up valuable spectrum for its mobile broadband networks, we may conclude that some markets or territories may need to sunset 2G even sooner. Should this be the case, AT&T intends to provide advance notice.
