Randynan:I noticed that you can now use your cell phone during the cruise. I was wondering how this works? Are you charged something by the ship each time you use it PLUS what your cell phone provider would charge for "roaming".
Carnival contracts with a company call Cellular At Sea (which has a website with that name) to provide cellular service throughout (most of?) their ships while you are out of the port. There are several 'pico cels' installed on the ship to give you coverage in most areas, and they work with most cel phone systems. The service is provided via satellite, just like the Internet service. While you are approaching and in port, you will (with roaming enabled) connect to the network appropriate for that area, either your home network or one that has a roaming agreement with your home carrier. Note that while the @Sea system is turned on you may get nearly full signal strength bars, but when it is turned off you will likely not get a signal anywhere deep inside the ship as the steel will shield the signals.
The charges for Cellular At Sea are supposedly set by your cel carrier, but seem to be $2.49/minute plus tax for at least the common ones. I got nailed $2.49 X 2 for the 3 second call my mom made as we were pulling away from Catalina. She got lost on the ship and called, then realized that the carrier showed @Sea, and hung up. Unfortunately I had answered... Ouch.
An interesting note, two of my tablemates on my last cruise had iPhones. Hers was first generation, his 3G. Hers worked, his didn't. So not every single cel phone technology is supported. among the major carriers (and technologies) Sprint (TDMA), Verizon (TDMA), T-Mobile (GSM), and AT&T (GSM) do work.
