The company Wednesday announced a plan to cover 96% of the U-S population with 4G-LTE service by the end of 2014.
Essentially meaning AT&T told regulators a big whopper last year while fighting for its doomed T-Mobile merger.
The company said without T-Mobile, it was "very unlikely" it would expand 4G-LTE service beyond 80% of the country.
The FCC called AT&T out, saying it believed the company was going to expand with or without T-Mobile.
AT&T says it never lied and circumstances had changed.
