Check out the following FAQ regarding the 3G compatibilities of the PS Vita and how to best take advantage of the features it offers.

1) How can I activate my 3G data service on my PS Vita?
Activating the 3G data service doesn’t require going to an AT&T store or even being at a computer. From right on the PS Vita’s home screen, touch the icon entitled “Network Operator” to launch into the process.

Once you’ve initiated the process, you’ll automatically drop out of any WiFi signal you’re attached to and begin syncing with the AT&T 3G service to pull up the activation site.
