I've been getting the message for all my contacts "This number is not available on the network

However I know that the contacts are correct and if I restart my S5 I can call theses contacts however after a few hours I get the same message and have to reboot, effectively, again. Also in this state an in call goes straight to voice mail. Any solution?
