AT&T will be the exclusive mobile carrier for Amazon's smartphone, the Wall Street Journal is reporting.

The publication's sources said that the phone, anticipated to be announced at an event on Wednesday in the online retailer's home base of Seattle, would distinguish itself from competitors with retina-tracking technology that would employ cameras to make images on the screen appear three-dimensional. AT&T already provides service to Amazon's Kindle tablet e-reader.

With such a technologically advanced smartphone, Amazon appears to be searching for an edge over competitors Samsung and Apple, which have cornered the smartphone market (one of every three devices sold last year was a Samsung, and Apple holds about 15% of the global market).

From 2007 to 2010, AT&T was the primary carrier for the Apple iPhone when it was first released. Though the two initially signed a five-year deal, in 2011 Apple also made the phone available Verizon

Earlier this year, AT&T signed a bundling deal with Beats Music, which arranged an exclusive offer with AT&T to give new customers a lengthier trial of the music service than for all other users; customers of the family plan could also pay a flat fee for up to five people on the same plan.

Representatives from AT&T and Amazon did not immediately respond to Billboard's requests for comment.
