Can someone pleas explain these to me. If we had a couple of them can you make free calls to them from America. Do they need to be on same network. Carer is worrying about calling home as all her family members only have mobiles. To expensive to phone daily. She has already said she will cry if she can not contact home. This would ruin it for everyone and there is no way i am paying a hugh phone bill just so she can chat to her mates daily. Any ideas.
