My question is if you have no cell or wifi service how would you contact someone? We are planning a trip that will take us to some areas that I have been told have no service so I am really concerned. Also there will be someone that had a heart transplant 2 years ago. Is there any type of service I could add that would give me constant service? Thanks.
