Why isn't my menu button working?

Hi,

To add a new APN

Go to Settings > Wireless and Networks > More >Mobile Networks > Access Point Names . You should now have a list of the APN's stored in your phone. To add a new APN you have to press the "soft button" on the bottom right of the phone. (On most phones there are three "buttons" along the bottom. Return, Home and Settings. It may vary between phones but they are basically the same).

This will bring up options, select New APN, then insert your information and save
