Phones and networks
3G technologies enable system operators to offer users a wider range of more superior services while achieving better network capacity through improved spectral efficiency.

The technical complexities of a 3G phone or handset depend on it’s require to roam onto legacy 2G networks. In the first countries, Japan and South Korea, there was no need to include roaming capability to older networks such as GSM, so 3G phones were small and unimportant. In Europe and America, the manufacturer and network operators wanted multi-mode 3G phones which would operate on 3G and 2G networks, which added to the complexity, size, weight, and cost of the phone. As a result, early European W-CDMA phones were appreciably larger and heavier than similar Japanese W-CDMA phones.
Japan's Vodafone KK skilled a great deal of trouble with these differences when its UK-based parent, Vodafone, insisted the Japanese subsidiary use normal Vodafone handsets. Japanese customers who were familiar to smaller handsets were suddenly necessary to switch to European handsets that were much bulkier and measured unfashionable by Japanese consumers. During this conversion, Vodafone KK lost 6 clientele for every 4 that migrate to 3G. Soon thereafter, Vodafone sold the subsidiary.
The broad trend to smaller and minor phones seems to have paused, perhaps even turned, with the ability of large-screen phones to provide more video, betting and internet use on the 3G networks.
