3G is a Free Wireless Signal ("Network"),
sometimes when 3G is good,
it also holds GPS signal.
3G is fast but not as fast as Wi-Fi signal,
when you're driving,
3G is very bad (and holds even less then 1 GB!),
when you're not driving,
3G holds around 12 GB.
Only if your 3G signal is on. If your 3G and wifi signal are both on and if your within wifi, it will use the wifi signal (connection) first.
When you switch off the 3G and cellular data in your iPhone 5 you get no service signal because of the poor signal provider.
You can boost a GSM 3G cellular signal by placing the device on a reflective surface like aluminum foil. This will bounce back some of the signal which will boost the signal.

No, you cannot. The iPad requires different hardware which enables it to receive a 3G signal from your carrier. The wi-fi model of the iPad does not have the black piece on the top of the back. the black piece is what receives the signal.
The iPhone 2G does not have the hardware to capture a 3G signal. It does not matter where you are.
There is a small chance you have no enabled 3G. To do this follow these steps. Go to Settings > General > Network and Enable 3G should be set to on. Also your area may not have 3G capabilities. In this case there is no 3G signal for 3G to work. To check 3G coverage contact your provider. Also if your iPhone is a 1st Generation and not the iPhone 3G you do not have 3G capabilities.
A 3G mobile is so good, because it means you can get goood signal from just about anywhere that has the slightest bit of signal, personally 3G mobiles are the only ones that are worth the money and if the phone doesnt have a 3G network then it is not a goood phone to be buying, although you can i think get a 3G network put in. But why would it be worth all of that money just to have this phone, i say get a phone with a 3G network and then you dont have to do anything to it. xxxx
In order to have active 3G on your Samsung Galaxy i9000, you need to have a decent signal. Phones that are 3G capable need to be in an area where 3G is readily available.
In Today, 2010, We Have 3G. But Maybe In 100 Years Time, We Will Have 4G. 4G Will Have A Better Signal Than 3G!
No, Its GPRS
When you go from a 4G coverage area to a 3G area with HTC Inspire 4G, the phone will automatically try to switch to the 3G network. However, sometimes the 3G coverage in this transition can be of a really low signal. What you need to do is reboot your phone to fully refresh its 3G coverage. This is how you can get 4 bars or more in your 3G signal. It's a small price to pay especially if you live in a 4G area, considering how fast its download and upload speeds are. With this small tip, you can get better 3G coverage on your HTC Inspire 4G.
