Dumb question - when you sign up for this what are you getting access to on your phone? We normally completely unplug while we are cruising so I've never needed this. We put all our phones in the safe and don't pull them out until we are back at PC. This time, DD18 isn't going with us as she is away at school. Long story - but we may need to be connected with her the first day or two of our cruise because of an activity on campus. If we buy the internet service, is that email and internet? I'm assuming it isn't phone calls and text messages. Just want to know going in so I can tell her how to stay connected with us.
