shabbat - Talking on the phone when it's shabbos for the other person

I am not religious, but I have relatives who are. I live in the US and some of my relatives live in Israel. Can they talk to me when it is after shabbos in Israel, but it's still shabbos in the US?

They would not be causing me to violate shabbos, I never keep it anyways. I really want to talk to them, and it's hard to find a time to do so because of the time difference.

Thanks!
