I have a boat and am frequently out on Massachusetts bay. My cellular
service (nextel) often has no service..What cellular company, based on
antenna placement and strength of signal, has the strongest reception
signal on the ocean on a line from 3-4 miles off the coast of
Gloucester, MA down to Plymouth, MA?

My Motorola Startac 7868 on Verizon consistently works perfectly over
much of Rhode Island Sound from Point Judith to Block Island while my
Motorola V-120 barely functions at the end of the dock.

A good part of cellular function is the phone and the Startac 7868 has
never failed. From waaaay out in the Nevada desert (where four other
phones on three different systems didn't work) to Hawaii, Puerto Rico,
and a dozen cities in between, the 7868 works flawlessly.

Problem is you can't activate one anymore. I tried.
