Yezz has announced plans to launch two new Windows Phone 8.1 devices in October for the European market, the Billy 4 and Billy 4.7, both of which are apparently named for Microsoft co-founder Bill Gates.

These phones will be the first for the company based on the Windows Phone OS, which shows that more OEMs are trying to sell devices with Microsoft's mobile operating system. The company announced earlier this year it was ditching its license fees for Windows devices that have displays that are smaller than 9 inches.

Yezz claims the Billy 4.7 phone will be the thinnest and lightest Windows Phone yet at 7.2mm, but the India-based XOLO WIN Q900s, that went on sale earlier this year has the same thickness as the Yezz Billy 4.7 and weighs just 100g. It's more than possible that both phones are based on the same design.

In any case. the Billy 4.7 will cost 199 euros when it is released in Europe in October and will have a 4.7 inch screen with a 1280x720 resolution. Inside there's a quad-core 1.2 GHz Qualcomm Snapdragon processor, 1 GB of RAM, 8 GB of on-board storage, an eight megapixel rear camera and a two megapixel front facing camera.

The Billy 4 will have a four inch display with a resolution of 800x480, a quad-core 1.2 GHz Qualcomm Snapdragon processor, 512 MB of RAM, 4 GB of storage, an eight megapixel camera, a 1.3 megapixel front facing camera and support for interchangeable rear cases. It will be priced at 129 euros.

Neowin reports that both of these phones are also due for launch in the US and Latin America but there's no exact word on when they will be released in those territories. Yezz plans to show off the Billy 4 and 4.7 phones at IFA 2014 in Berlin this week.
