I currently have a TCL Flip Pro prepaid. I will be in Portugal next week and would like to be able to call in Portugal(locally). I called Verizon and they said with my current plan I could not add international calling. I do have an extra identical TCL Flip Pro that has not even been out of the box yet. Could I set that up for service in the States and add international calling to that? Or take it with me to Portugal and set it up there? I do not want to take it with me if a prepaid phone cannot be set like that.
