Every time I send a text message it says sending message for a long time then it say sending failed yet the reciever of the message has actually recieved it. So now every time I send a text it does this. Is there a way to fix this? And this is the 3rd time this has happened with this model phone for me and I've swapped it in to Best Buy several times due to issues but this issue just seemed to always pop up.
