I did all the necessary steps. then i found out i typed in my cell address incorrectly. i went to 'modify account', deleted my old entry, and typed in the new one, made sure that i had the option of getting messages sent to my phone, and clicked update. I clicked back on 'modify account', scrolled down to the cell address part and saw it still had the previous incorrect address, so i went through and changed it again. i did this about 7 times. my modifications won't take! WHY!!!!!!!!!!!
