Sat TV underway is expensive in both equipment and plan. We have a small TV, but use it mostly for DVDs on rainy days. Have a
cheap digital
antenna for over the air TV, but outside US this not readily available. Really, so much to see and do you wont miss the TV.
Internet. Suggest a few methods. Hotspots at cafes/bars with
laptop. Powered
wifi antenna like a
Rogue Wave for the
boat. Local data plan for your smart
phone and use it as a hot spot. We use all three.
Phone. Calls get expensive, especially with roaming. Look at an unlocked GSM, quad band smart phone. Get a local SIMM and add a data plan. Set up a Skype account, this allows you to Skype call to most any country for 0.02/min. Can call to a land line or another
cell phone. As well you can then Skype or use facetime for android/google app for free when contacting someone on same service.
T Mobile offers a roaming free international data plan but it has mixed
reviews. It works but seems the data rates in many places are slower than getting a local simm and data plan.
