That’s what is so frustrating! From everything that I have read and been told, he SHOULD be able to do just that – simply hit reply and the message be directed, but I just never receive anything… The same thing happened when he tried to reply to my mother’s phone (the same provider as me), no message was ever received. And whenever I call US Cellular, the person I talk to never seems to know that much about international texting so they end up being just as confused as I am..
