First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
3G Mobile Phones

In Australia, the 3G network uses the UMTS standard, which is built on the GSM network and all four operators - Vodafone, Telstra, 3 Mobile and Optus - use this standard. The other 3G standard is CDMA2000, which has a number of variations, but only Telstra has a version for mobile broadband packages. (See Networks & Data Rate box below for speeds and the Glossary for technical terms related to 3G networks.) Theoretically, any UMTS 3G-compatible phone will work on the UMTS network with any operator, although limitations or restrictions may be imposed by the operators as the service develops. But the phone companies are offering a selection of handsets with plans, which limits choice but avoids compatibility issues.
