I have been having a lot of issues since switching from AT&T to T-Mobile when it comes to receiving SMS messages which were sent to me via email. I rely upon this functionality and it needs to be much more reliable than it has been. Today (February 28 2014) I have not been receiving any messages sent in this manner. I have tried sending test messages from several different email accounts with no luck.
Recently, I received messages but they were hours late and all three showed up at once. I really need help with this. I am aware of others who are on T-Mobile that are having the same issue.
