this is a new problem on my g4. all of a sudden I can not send text messages when i am in my home. this happens on my s4 and my sons s4 but my daughter uses an iphone and she is not having this problem. i can receive texts, facebook, email etc I just can not send texts. Nothing in my house has changed except that Comcast just put in a new modem, I am not tech savvy at all so not even sure that would affect my out going texts
any suggestions would be great
