Now that smartphones have become fairly ubiquitous, so too have the terms 3G and 4G. Wondering what the difference is? We’ve got the lowdown for you, along with a few tips that’ll help you decide whether or not you need to dish out the money for a shiny new 4G phone.

On the surface, the difference between 3G and 4G is pretty simple. The “G” is short for generation, so 3G and 4G represent the third and fourth generations of mobile broadband Internet. As a rule, provided that you’re on the same carrier, a 4G connection will be faster than a 3G one. However, that doesn’t necessarily mean that a 4G network of one carrier will always be faster than the 3G network of another.
