Is it possible to make phone calls on sea days to the U.S? I am going to need to check in with my 81 year old mom while I'm gone. We have 4 sea days total, 2 at the beginning and 2 at the end. She only has a flip phone so it's not like I can face time here (not that I know how to do that LOL). Neither of us are that tech savvy. She doesn't know how to text so I really can't see any other way than to figure out how to call her, but I don't even know if that's possible.
Any ideas would be greatly appreciated!!
