I switched to the s5 from a Chocolate 3 which I had been using for several years. For about the first week, everything went fine with the Galaxy. About a week ago, I started having some issues with SMS. Sometimes I will receive messages several days late and sometimes not at all. These messages are being sent from both Android and Apple devices. I called support three days ago and was told it was most likely a network issue and would be resolved soon. The problem still persists. I've tried using Hangouts (my preferred messaging app) and tried uninstalling Hangouts and using the default Samsung messages app. The problem occurs with both.
Please help!
