We were greeted by the sight of a second cruise ship that dropped off supplies and amazingly we were able to pick up a cell phone signal from the other ship.
So while the phone may have GSM network access on shore (because no CDMA signal is found), that is not the case when you are on a ship because ships provide both GSM and CDMA cell sites.
Not to be forgotten, 2011 is the year Motorola will spin off its cell phone company, and it seems to have righted the ship based on its 2010 sales figures.
