Ok Joe thanks, good at least that a confirmation on that.

The person at least did receive my text, but it went in a shared thread/ message, where everyone else saw it as well.

So now know, have to make seperate cards. Pity, like you have married couple separate phone numbers and names in one contact card, and have message with one. Then send message to other, and they blend into same message.. just BS IMO.

In effect as you say have to make separate contact cards... And Apple does this even if just typing in phone numbers direct to message without the card involved!
