I know zero about this topic, so I need some guidance. I want to be able to connect to the internet on my upcoming ICW trip down to the Keys. Once there I will have internet at my marina so I only need to get coverage for maybe 2 months; therefore, NO CONTRACTS. I do know that I will need to purchase some sort of USB device and then pay for a month by month plan. Investigating on-line just serves to confuse the issue. Someone out there please recommend a relatively inexpensive device/plan that will give me the best coverage while transiting the ICW.
