Whereas we had an
Iridium 9555 aboard, we opted to not buy a SIM for it while we were in
Indonesia. There’s a good Sail Mail station in Brunei and we could always connect easily and had good download speeds.
Since we were in many
remote parts of Indo, our
cell phone was of little use. However, I assume that if you were in more populated areas, a cell
phone would
work well for gathering weather information.
Good luck, fair winds and calm seas.
