I use the Verizon Family plan, so for $43 a month a get something like 300 minutes, free long-distance. I have a $19 cable I can connect the phone to my laptop and use it as a wireless modem. Works great at 19000 baud. If I want to upgrade, I can sign up for their "Network Express" service at $80 a month for 128k connection speed, but I''ll have to get a new phone that is supported.
I also got a phone that has an external antenna port, and another $19 cable that will hook it up to an external cell antenna, but so far I haven''t had any problems getting a good signal. I just put the cell phone on top of a locker and it''s worked fine even in some remote areas.
I would like to hear more about high-speed access at Marsh Harbor. Is this through a cell phone provider, or via WiFi connections at marinas?
