I'm going to France in 2 weeks and got a 600 text and 300 minute freedom pack to use from now to then and then in France. I tried to text my dad who has bought a new phone in a America as his UK bought phone doesn't work there. When I tried it said I didn't have enough calling credit. I'm wondering if I need to get a normal top-up to call home to the UK or will my freedom pack work when calling UK phones.
Thanks for answers!
