In this dialogue, "to do that" might mean "to send secret messages" or "to send secret messages for drug trafficking". I presume there's a bit of similar ambiguity in the actual conversation. It's also possible that as a sales pitch, the defendant may have intentionally meant the former while subtly implying the latter, where the former is almost certainly true and the defendant might know the latter to not be true. Though, I imagine for a variety of reasons it's unwise to play phrasing ambiguity sales games with drug cartels. His first mistake was of course getting into a situation where it was possible to play these games with presumed cartel members.
