EVDO can shorten your Motorola e815’s battery life. Since Page Plus, my cell provider doesn’t support EVDO, I disabled it on my unlocked e815 with the following procedure:

Enable Test Mode

  1. Quickly press the Menu (top-center) key, then 073887*.
  2. Enter your security code when prompted. By default, this will be 000000. If you aren’t prompted for your security code, go back to step 1. You probably didn’t type the sequence in fast enough.
  3. Scroll down to “Test Mode”, and press Select, then Enable.
  4. Press Exit to go back to the main screen.

Disable EVDO

  1. Press the Menu key followed quickly by the Left Soft Key (top left key).
  2. Press the Left Soft Key until you see “HDR Pref” and “HDR Hybr” (around 5 times).
  3. Scroll up to “HDR Hybr”, and change its value to CDMA by pressing the Right Soft Key.
  4. Scroll up to “HDR Pref”, and change its value to Off by pressing the Right Soft Key.
  5. Press the Left Soft Key to select Exit.
  6. Press the End button to go back to the main screen.

Disable Test Mode

  1. Quickly press the Menu (top-center) key, then 073887*.

  3. Scroll down to “Test Mode”, and press Select, then Disable.
  4. Press Exit to go back to the main screen.
