Although the release dates for the two smartphones are coming, we don't know all the details about them, both still keeping secrets until the day of them release. However, AT&T was the carrier that provided the most information on both smartphones, HTC has started to take preorders for HTC One even before its release date. It will be available in the 32GB version for just $199, while the 64GB at AT&T will have a price of about $299, and the official release date is April, 19th.
Instead, at AT&T Samsung Galaxy S4 will be available in two versions: the 16GB version and the 32GB version for that price will be $199, respectively $249, and preorders can be taken by the carrier since April, 16 th, so only three days before his opponent.
At Sprint, the data are broadly similar to those from AT&T, the U.S. carriers are not too interested in smartphones from Samsung with 64 Gb and at Sprint too the opponent will get ahead of Galaxy S4 with the data release.
U.S. Cellular and Verizon have not yet confirmed many details about the release dates, prices, specifications or plans, but probably the releases date will be the same, it remaines less than 10 days until the release data on almost all carriers from U.S., among them already existing a fierce competition in terms of preorders.
