We are doing a ride in the remoteness of NSW/SA/NT and WA in August and, being two bikes alone, we have both technologies.
Now for the second part…
I know its a cost, but for a cross country ride, we are both going to take sat phones… For a few hundred bucks to hire for the duration, I want to be able to call at any point and more importantly, I want to be able to be contacted in case of emergency. I have not determined who I will be hiring off yet or the final costs, but I have estimated $600 for the three weeks, calls inclusive… If it goes over that, then it is my fault and I am paying for the luxury of saying night to my kids – worth it for that alone.
Anyway, thats my two bob, hope I have been of some help.
