In September 2006, the W-ZERO3[es], model code WS007SH, was released, boasting a revamped form factor, weighing just 175 grams (compared to the W-ZERO3 and its 220 grams).

The display is, unfortunately, much smaller – down to 2.8 inches. Apparently, Willcom took users' feedback on the original WS003SH into account, with some complaining that it was too large and awkward to use for phone calls. The WS007SH addressed these concerns with the smaller display and also added a numeric keypad for dialling, making the design closer to that of a conventional mobile phone.

The size of onboard storage also got clipped: down to 128 MB At least the resolution remained high enough: VGA (640 × 480 px).

Decreasing the display size while keeping the resolution brought two "firsts" for the WS007SH: the industry's first 2.8-inch VGA display and the industry's first high-definition LCD.

Besides the form factor change, the W-ZERO3[es] has no differences from its predecessor. The OS is still Windows CE, again version 5.1.195. The processor stays the same Intel XScale PXA270, and so does the amount of RAM (64 MB).

Although the WS007SH no longer had built-in Wi-Fi (like the WS003SH/WS004SH), it supported SDIO and USB host functions, allowing users to expand its capabilities with accessories such as miniSD Bluetooth or Wi-Fi cards, external keyboards and removable drives. A dedicated optional tuner could even be connected to watch One-Seg digital TV broadcasts. The device also supported call waiting, and a dedicated sliding switch made it easier to lock the screen and buttons when not in use.

The W-ZERO3[es] measures 135 × 56 × 21 mm and weighs 175 grams. It is offered in black or white.
