*228 will most likely not work as his provider is Bell and not VZW.
As far as not receiving calls, trying updating the OS on the device and see if that helps.
Have you tried to power-cycle the device, pull the battery out for 1 min and place it back in?
If not place a call to Bell support for voice network issues, have them look to see if it is something on the network side.
Hope this helps!
