The phones firmware needs to be upgraded. This is a common occurrence.
1) Look at the back of your phone and take out the network cable from the port that says "SW". When you unplug it, your phone should turn off.
2)Then at the same time, plug back in the cable while you are holding down the # button on the phone. Keep holding the pound # button until you see orange lights flashing on the right of your phone.
3) Once you see the orange lights, release the pound button and just hit in order 1,2,3,4,5,6,7,8,9,*,0,#.
Your phone will reboot and update. It takes the phone at least 10- 20 mins to upgrade the firmware.
