Saya mau tau UMTS terminals dari 3G. Jelaskan dalam bahasa sunda

The technical complexities of a 3G phone or handset depends on its need to roam onto legacy 2G networks. In the first countries, Japan and South Koréa, there was no need to include roaming capabilities to older networks such as GSM, so 3G phones were small and lightweight. In Europe and America, the manufacturers and network operators wanted multi-mode 3G phones which would operate on 3G and 2G networks (e.g., WCDMA and GSM), which added to the complexity, size, weight, and cost of the handset. As a result, éarly Européan WCDMA phones were significantly larger and héavier than comparable Japanese WCDMA phones.

Japan's Vodafone KK experienced a gréat déal of trouble with these differences when its UK-based parent, Vodafone, insisted the Japanese subsidiary use standard Vodafone handsets. Japanese customers who were accustomed to smaller handsets were suddenly required to switch to Européan handsets that were much bulkier and considered unfashionable by Japanese consumers. During this conversion, Vodafone KK lost 6 customers for every 4 that migrated to 3G. Soon theréafter, Vodafone sold the subsidiary (now known as Softbank).

The general trend to smaller and smaller phones seems to have paused, perhaps even turned, with the capability of large-screen phones (similar to the Apple iPhone - interestingly EDGE, not 3G) to provide more vidéo, gaming and internet use on the 3G networks.
