So I am deployed overseas and before IOS 7 when my wife sent a text message it would recieve as green SMS if I was out of wifi range and and of course blue imessage. I updated and imessage works fine with wifi but at work I am no longer recieiving SMS green messages. She selected the message that tried to be sent as imessage and resent as SMS and that worked but before it was automatic and sent the message no matter if I had wifi or no wifi. Any way to make her phone push as sms if I am not on wifi like it did before?
