The modem comes in the form of a stick that is compatible with both Windows and Mac OS X computers and works by giving users access to Telus' EVDO network. The device has its own internal memory and can install the necessary drivers on its own.
The USB 598 also has a microSDHC slot to allow for up to 32GB of data storage on top of the modem functions. If you sign up for a two or three-year contract, you can get the USB 598 for free. However, if you want to buy it outright, you can expect to pay $199.99.
