Thanks for posting that. I'm sure I have an email somewhere telling me about it that I've ignored. There are some good things from my perspective as an annual account user like more messages included. Since it isn't an annual contract I can move service levels and downgrade for months I don't have long trips planned.
I have a second device my wife uses once or twice a year on her solo trips which has a Freedom account. Looking at the details on that page I'm wondering if we can just leave it Enabled. It looks like you can still use the device, just paying per message with a 10 cent fee for check ins rather than free. If I am reading that right there doesn't seem to be much reason to upgrade to Essential for her trips. Am I missing something there?
