This depends on service availability in your area, and where you want to go. Verizon, Sprint, AT&T, and t-mobile all offer 3g.
AT&T is a network and they do have a 3G network. They are not considered a 100% 3G network because they have a lot of different options.
No we can't use different network 3G sim in Vodafone 3G sim.
The iPhone 3G is capable of accessing a 3G network. Some of the older iPhones and the new iPhone 4 can not access a 3G network, however. There are many droid that have the same applications as the iPhone but that will hook up to the 3G network.
at a 3g network i get600+kbps
3G phones are enabled with the ability to connect to the 3G network. It is a high speed cellular network.
Cricket is a great 3g provider. You can get unlimited service for about $40 per month. The service is reliable and reasonably priced.
no ,it only support gsm. not cdma not 3g network
I have used it over a 3G connection, yes but calls can drop or have noise interference. Best to be in a fixed location.
Sprint has a 4g network that is multiple times faster than the competition 3g networks, in addition to the equivalent of 3g coverage where 4g is not available. Coverage for 4g is not universal and only a small part of the country, mostly in cities, will have 4g coverage.
No, I do not think the blackberry 8700g is available on the 3G network. http://www.blackberryforums.com/general-legacy-device-discussion/22540-new-3g-network-8700c-compatible.html
You asked what a good example of a 3G network? well My favorite 3G network would be verizon, they are dependable and you can go cross country without dropping. They are cheap too.
Yes, it supports 3G network.
