Nokia launched two Windows Phone 8 (WP8) smartphones back to back in the U.S; the Lumia 928 launched on May 10 (which is heading to Verizon) and the Lumia 925 launched on May 14, which was meant exclusively for T-Mobile. However, new reports suggest that the Lumia 925 is also being tested on AT&T.
A recent Nokia Power User report indicates stats captured off Occasional gamer shows the Lumia 925 on AT&T's network. Moreover, Nokia Developer website confirms that the U.S. variant of the Nokia Lumia 925, model RM-893, does support LTE band 17 (700MHz) which is used by AT&T.
The Lumia 920 is currently exclusive to AT&T and speculations indicate that Nokia is planning to launch the Nokia EOS on the carrier. With T-Mobile and Verizon both getting an exclusive WP8-powered Nokia smartphone, it should not come as a surprise if the EOS is announced as an AT&T exclusive.
A Phone Arena reports points "If a customer bought one from T-Mobile outright and was not bound by an equipment purchase plan, it would allow them to use the device on AT&T's LTE network. It is also possible that AT&T will offer the Lumia 925 to replace the 920 after the T-Mobile exclusivity period ends."
It seems that AT&T customers may soon be able to use both the Nokia Lumia 925 and the Nokia EOS on the carrier's LTE network. However, no official announcement has been issues by AT&T.
Currently, AT&T has only a handful of WP8-powered smartphones on offer which include the Nokia Lumia 920, Lumia 820 (web only) and the HTC 8X. The top-end Lumia 920 has a price tag of $99.99 on a two-year contract and is also available outright at a price of $449.99. AT&T customers will be happy enough to see more WP8 smartphones in the carrier's portfolio and the addition of top-end smartphones like the Nokia EOS and probably the Lumia 925 will be like icing on cake.
