Latest questions about "at t"

Using my Samsung Galaxy S3 on the AT&T system, I was previously able to delete voice messages by pressing 7. This no longer works. I can press 7 multiple times and the message continues to play.

I used IncrediMail for 3 years and I had no problem until now. AT&T changed their Pop and STMP codes and now is using SSl. I cannot send and I cannot receive any email.
