If you need to be in contact with loved ones, girlfriends, mistresses, ex wife's ( sorry had to add that) mobile reception is patchy.
I carry a prepaid Telstra phone and can get signals at cooktown, coen, and the Cape. You may pickup the odd signal here and there. I also had an IPhone 4 with optus and got a signal at cooktown and at Seisa caravan park as well as the Cape it self. iPhone 3 does not pickup with
Optus.
Tim had his satphone which he got a signal in most places. He may bring it next year for safety precautions such as ordering a pizza or flying in kfc....
