Today my Samsung Galaxy S5 would not allow me to access the phone funtion. Each time I tried to access the phone the usual Dial screen Appeared, but was quickly replaced with a message saying: "Contacts Temporarily Unavailable". The screen immediately reverted back to the Apps menue. I am unable to make any out going calls nor see my missed calls
or make any out going calls. Please Help. And, YES, the bill is paid.! Any ideas, PLEASE?
