report from WMPoweruser has highlighted a little trick for users of Nokia’s Lumia 900 Windows Phone discovered by the guys at MobilityDigest.
The process which will be listed after this is to allow a selection for the maximum connection speed your Lumia 900 can access to AT&T’s network with.
The information directs users to type ##3282# into the dialer and it will open the Data Field Test utility, tap the three, tap and open ‘Settings’ at the bottom of your screen, the network type can then be changed from 2G or 3G only to ‘Automatic’, tap the ‘Back’ button once to go back to the ‘Field Test’ menu, tap the last option on the screen which is the ‘Toggle ENS’ (reboot), after it opens, tap ‘Start’, after a few seconds, tap ‘Stop’ and your phone will undergo a soft reset (reboot) after a slight pause.
When the phone starts up again, go to ‘Settings’ and then enter the ‘Cellular’ menu where you will have the option to select E, 3G or 4G as your highest connection speed.
