APN Settings is a handy application that lists all the Access Point Names that you can find across the globe. It gives you the ability to search by country name and type of Access Point. It is useful in case you have a different mobile network that you want to connect to the Internet and you need to know the name of the Access Point. You can also add the Settings as a favorite so you don't need to go through the hassle of opening the app every time.

The APN Settings app also gives you the option to search the Settings by the Operator Name.
