Minimising Iridium Airtime Costs

I have an Iridium phone on board which I use for emails when out of reach of wifi / mobile phone etc. I have always tried to eliminate un-needed connections when using it such as automatic updates for software etc. I used to use it on a windows machine but have just invested in a macbook and am looking for a way to check that nothing else will be using the Iridium connection when I am emailing. Any tips or software which might help me track down unwanted connections?

Richard.

Iridium & Inmarsat Satellite Phones with Backup & Support | MailASail do a service where they compress emails, not free but did seem to work well, i tried a friends account offshore. great place to get free gribs & text forecasts via email as well.
no use to you but maybe to others - NetLimiter - The Ultimate Bandwidth Shaper do a great little program which shows download and upload speeds, and you can limit individual program speeds or stop them accessing the net altogether. Maybe similar prog for mac somewhere?

little snitch

I have used netlimiter before on PC. Just did a search for mac and found Little Snitch which looks like it should do what I need.

Also check to see what the "billing increment" is from your airtime provider. It makes a big difference in overall costs, depending on whether you pay for, say, a 2:00 minute call after using the phone for 1:10. If you can find a 20- or 10-second billing increment, it will save you much money, esp. if many of your calls are short ones for checking email, where the 1-59 seconds of "extra" time make up a substantial percentage of the call time.
