How come I get a "security certificate warning " everytime I sign in..??

Try changing your password to be a word or whatever and then a number at the end.

Okay.....it only does it on my cell....but not on home computer ..

Does your cell phone have cookies enabled? Even if you accept the cert, the next time you log on it might ask you again. You might also need to update a app like taptalk or whatever you are using.

Wrong date, time zone and time can even cause it. There should be some setting you can adjust in your browser app like Enable/Disable Security Warning.

Its still does it everytime ..Im changing to At&t...maybe that will clear it up...we will see.
