4. Under Library there is a Configuration Profiles, Click on “New”, go down to advanced, add the APN settings, for example in Malaysia, use Access Point name “maxis” and password, “wap”, rest not needed, at least not for Carrier Maxis

5. Connect your iPhone, should pop up as in iTunes, go to “configuration profiles tab”, chose install, a notification should appear on your phone, choose “install”. After install it should work directly.

Only one profile can be installed at once; which is not good, because if you have different pre-paid cards, you are not able to switch profile until you go home. For iPhone 4 with iOS 4, the APN settings is under General > Network.


  • Look in Devices/<phone>/Console for error messages.
  • In your Settings/General, you should now have a profile-tab, so you can choose to remove it if you experience any other problem and redo.
