• Answer:

  First of all, please check that you have used the following procedure: Click on "Messenger" in the top left hand corner of the Messenger Toolbar. Click on "Preferences". Click on "General". Click on "Edit Mobile Phone" at the bottom. In the "Other Mobile Devices" section, click the trash can Icon which is under "Delete". (There should only be one entry to delete.) The "Delete this Device" window opens. Select "Remove alerts for this device" from the "Delete this Device" window. Click "Delete Device" to confirm. When this is done, add your new Mobile as follows: Click on the little mobile phone icon under the Custom Status message box. Click on "Set up Mobile Phone". A new window will open up to enter the details of your new mobile phone. Enter the telephone number of your mobile device in the "Number" box and click on "Continue". You will receive a text message with a confirmation code on your mobile device. The "Get Yahoo! Messenger on Your Mobile Phone window" changes and it asks you for the confirmation code you just received on your mobile device. Enter the 4-digit confirmation code in the "Enter code" box and click to select the check box option for "Automatically sign me into my mobile phone when I log out of Yahoo! Messenger on my PC". Click "Next". (The Get Yahoo! Messenger on Your Mobile Phone window changes to tell you that you've successfully registered your mobile device.) Click on "Done".
