The ITU has not provide a clear meaning of the speeds users can expect from 3G gear or provider. Thus users sold 3G service may not be able to point to a characteristic and say that the speeds it specifies are not being met. While stating in comments that "it is expected that IMT-2000 will give higher transmission rates: a least amount speed of 2Mbit/s for stationary or walking users, and 348 kbit/s in a touching vehicle," the ITU does not actually clearly specify least or average speed or what modes of the interfaces qualify as 3G, so various speeds are sold as 3G planned to meet customers outlook of broadband speed. It is often optional by industry sources that 3G can be predictable to provide 384 kbit/s at or below walker speeds, but only 128 kbit/s in a touching car. While EDGE is part of the 3G standard, some phones report EDGE and 3G network accessibility as separate things, particularly the iPhone.

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.
