Meteor - Going abroad?

I'm going on holiday this year to France. I live in Ireland and am on the Meteor network. As is my boyfriend. I was wondering, about when I do go on holidays, will I be able to talk to him, and text, and how much will it cost. I've looked it up, but I am kind of confused. I mean, will it cost money from HIM to ring ME from Ireland to France? That's my main question and I would really appreciate an answer :) Thanks!!
