ICQ Alternatives for Windows

Negative Comment by martinjohn1
about ICQ Aug 2016

Hmmm - it asks for me to enter my country code and phone number, then returns a red message saying "Perhaps you are entering a city phone number"
No explanation of what it means, what alternatives there are, or how to proceed.

I can only assume that only people with moblie phone accounts are allowed to sign up.

ICQ used to be a decent IM client/service. Then it became bloated and extremely prone to spambots.
