ICQ version that allows chat between PC & phone-without-wifi

I understand that ICQ used to allow exchange of SMS between PCs and phones-without-internet (before there were 'smart' phones). ICQ has not answered me whether that is still available. I need that facility now. The latest ICQ needs internet. Old ICQ versions are available. I want to know if that old-style ICQ still works, and if so, what latest version should be installed on the PC and also what latest version on the phone.
