How do I use my ICQ number?
Log-In via Phone Number Registering in ICQ is very fast and simple: you only need to enter your phone number and confirm it via text message. If you already have an ICQ account, you can log in instantly via e-mail or UIN. Once you connect to your ICQ phone book, it will display your friends who are already using ICQ.
