What's the difference between 3g and wifi on a mobile phone?

i'm looking to buy a new mobile phone


i preferably want to be able to get on to the internet wherever - can i do this when a mobile has wifi?|||3g refers to the cell phone service - their towers. It's generally slower for web browsing than wifi.


Wifi refers to an actual internet connection (like you would have through fios or comcast). Your phone has the ability to connect to your internet (or any unsecured wirless networks you come across) and access the internet that way (similar to the way a computer does).





Often, if you use 3G to access the internet, you'll be paying for a data plan for your phone, which makes your monthly bill more expensive, but guarantees you internet access anywhere your cell phone can get service.





*Edited to add*: if your phone only accesses the internet through wifi, then you'll be able to get internet on your phone anywhere that has a wifi (wireless internet) connection. Many restaurants/libraries/stores have wifi. Many houses have wifi. But you probably wont be able to have internet access as you're driving down the road.|||3G stands for third generation, referring to third generation cell phone technology.





A phone with WiFi indicates that the phone can connect to wireless local area networks.





You can connect to the internet with either technology.





The key differences will be:


3G - Connect anywhere your wireless provider has data coverage (larger area). You will incur data charges without the appropriate data plan.





WiFi - Connect anywhere a wireless network is available to you; this can be at your home, the mall, McDonald's, etc (more location dependent than 3G). As long as the wireless network is being provided for free (many business offer free WiFi hot spots), no cost will be incurred.|||You can consider buying
