Samsung Galaxy S Relay not receiving texts from Android based Moto G

[idtwin2]

We use Consumer Cellular and just started having issues receiving texts from Moto G to Samsung Galaxy S Relay. Texts are received from the Galaxy to the Moto G and CC has provided no solutions. We have had service for 1 year and had these phones for 3 months before having any issues. We are able to send and receive text to mutual contacts, any suggestions are greatly appreciated.
