> you are "not too familiar with Tor", but still state everything with an almost absolute certainty. When it comes to security I'd rather err on the safe side and call it insecure until proven otherwise. In any case, even if we assume the Tor part is secure, this is still unnecessary at best, since it requires you to run a local Tor daemon. You can run one on a normal SIM, and probably end up better off since you're not putting yourself on a hypothetical watch-list by purchasing such a product.
