Miami — DDM Brands, which makes unlocked Yezz-brand cellphones, launched its first two Windows phones, one said to be the thinnest Windows Phone 8.1 smartphone announced to date at 7.2mm (0.28 inches).
The thin Windows Phone is the $249 dual-SIM Billy 4.7, which it plans to roll out globally in late May starting with Europe, Latin America and the U.S. It will be rolled out along with a lower-cost version, the Billy 4.0, at $139. Both feature HSDPA+ 42.2Mbps data in the 850, 900, 1900 and 2100MHz bands, so they will operate in the AT&T and T-Mobile networks.
Both also feature Qualcomm Snapdragon 1.2GHz quad-core processor.
In the U.S. both will be sold exclusively at Amazon.com and Sayyezz.com.
The company’s other phones are Android phones, which are available on Amazon, eBay, and the Sears and Newegg websites. One phone series is the Andy series.
The company has been selling unlocked phones in the U.S. for two years.
The Billy 4.7 features an aluminum-wrapped chassis, 4.7-inch 1,280 by 720 HD IPS display, Qualcomm Snapdragon quad-core processor, 13.1-megapixel camera and Corning Gorilla Glass 2. It comes with three interchangeable covers in red, white and blue.
The Billy 4.0 with a 4-inch 800 by 480 screen at $139 features an 8-megapixel rear camera and 1.3-megapixel front camera.
Last month, Nokia unveiled the Nokia Lumia 635, which T-Mobile and AT&T plan to offer and which T-Mobile expected to be the first Windows 8.1 phone available in the U.S. Its depth is 9.2mm, though it incorporates LTE and HSPA+42.
