How do I link a phone number to an existing ICQ account?

In order to link an account, do the following:

  1. Sign in to an ICQ account that is not linked to a phone number (sign in using your UIN/password).
  2. Tap the "Attach Phone Number" button located on the side menu.
  3. In the appropriate field enter a phone number that is not linked to an ICQ account and tap "Next".
  4. Enter the code from the SMS message.

Once all of the steps have been completed, the app will display a message saying that the phone number was successfully linked. Now you can sign in to your account using both your phone number and your UIN!
