It has happened many times try this ( I posted this in another thread )
1.download Any cut from play store.
2.on home screen try to open a shortcut
3.after you select shortcut select "any cut" (the app)
4.go to activities
5.let it load (it may takes few mins)
6.then scroll down until you see CDMA options (IT HAS TO BE THE FIRST ONE), then select it
7. so now CDMA should been in your home screen, press it and it will restart CDMA or reset the configurations. ( it will foreclose )
8. After that put the phone in airplane mode and then back to normal...
