How do I link a phone number to an existing ICQ account?
In order to link an account, do the following:
- Sign in to an ICQ account that is not linked to a phone number (sign in using your UIN/password).
- Tap the "Attach Phone Number" button located on the side menu.
- In the appropriate field enter a phone number that is not linked to an ICQ account and tap "Next".
- 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!
