I had gotten a few of these so far and I find it annoying. I have searched online and cannot find a way to stop it but from what I hear it is using the Mobil Email that comes with the phone. Here is what my text say. OZMAIL CI=689b3aa42141fe04370588fo191c1127 MC=1 To Stop these messages simply reply to this one (charge may apply)... Now when I searched they all said that it will not work when replying STOP of any way. Is there another email app I can use instead of the mobile app that came with the phone.
