The authorities in those countries already ban importation of unlicensed communication devices and severely punish anyone caught in possession. A few will be smuggled in but not enough to effect any real change.

I do think though that the CIA should at least take advantage of this new technology to undermine hostile foreign governments. Mass produce a few million cheap satellite phones and use balloons to scatter them all over China, North Korea, etc. Even if it doesn't have much practical effect, the overt disrespect will help to undermine our adversaries and force them to expend more resources on tightening internal security controls.
