The phone is the first smartphone reaching the market to employ the Microsoft Mobile for Smartphones 2003 operating system.
In short, there is a Pocket PC stuffed inside this innocent looking phone handset.

It’s nice to have all this stuff inside a small, portable device, but how does the user get words and thoughts inside? Sierra Wireless thought long and hard about this –- and came up with a unique solution: a flip-open QWERTY thumbpad.

The bottom third of the phone opens to reveal 46 little buttons in a typical keyboard layout. The buttons are small, but functional. Use a Voq for a few days and you begin to get very fast inputting data.

As for the phone itself, it worked just fine in all my tests. I had a very early Alpha version of a Voq at the beginning of the year. I was impressed with its e-mail handling abilities. At the time, I was still able to use portable devices to retrieve e-mail from MSNBC servers. Utilizing VoqMail software, the device has the ability to receive e-mail via VPN –- a very clever solution to running software on the server or via desktop redirector software (like a Blackberry). It worked flawlessly. Nine months later, VPN is no longer an option for me -– so I tested the Voq with POP3 and IMAP mail from some Internet service providers. It did very well at that too.
