I'd like input on the best means of obtaining laptop internet access while on an expedition trip. We tried the AT&T broadband internet card last time along the Gulf Coast, and found it horrible. Coverage was poor along the coasts, the contract was restrictive, the costs exorbitant, and while they advertised 4G service, customer service was zero-G. I looked at Net Zero, and their coverage area is minimal. So, when paddling along the coast or down a river, any other suggestions on what is the best way to maintain communications capability by laptop?
