It is almost becoming common knowledge for anyone with a satellite phone, or someone intending to have one, to get the right accessories for the device. This is the only way to guarantee both ease of use and long-term satisfaction.
For many people, usage of a satellite phone comes in a myriad of situations such as, while on the road, at work, in the field and at home as well as while flying. As you consider these different scenarios of usage, you will be able to come up with a fair estimate of the type of accessories that you mostly need for your daily use. For example, most people will need cables or cable extensions and plugs, cases, protective covers, software for synchronizing data with other devices and Australia SIM cards for the network service from your provider and billing.
A satellite phone is quite an investment for almost anyone, and protection comes first, on the list of add-on features. Getting a waterproof case that does not hinder the normal operation of the device would be a good first choice. The next purchase to consider would be the battery. You cannot use a dead phone. Getting a charging cable with universal socket adapters is a remarkable choice. It lets you travel without having to worry about not finding a compatible socket port for your phone. A cable extension also allows you to reach your phone and use it without having to unplug it from the mains power. This would also come in handy at home, if you have children as they can accidentally whack the cable. For a long cable, the severe effects of the accidents are minimal.
Lastly, you should consider having at least two sets of every accessory that you get for your phone, and place them in different locations. You may have one for the car, and another one for the house or office. This not only gives you a back-up solution when you leave the primary accessory behind, but it also lets you eliminate extra components in your luggage.
