So what happens if you have a flight that gets diverted to India and they search your bags and find a satellite phone?
Which is that it depends on the mood of the person in charge. Either you get to keep it, or it's confiscated and destroyed, or you go to jail, or you go to a firing squad.
We can guess which is more likely in each country. Indonesia almost always executes people found with drugs. Australia would probably just destroy your pineapple. India, being authoritarian but not completely insane, my guess is they'd take it and fine you.
..what? Condoms are not outlawed there, are they?
Whatever will happen with you lawyering and fighting the border officers, will happen after you've been detained.
