If you're speaking of, "texting" via a wireless device, no there's none of that. A patrolling nuke has only limited contact with the outside world and that's in the form of one-way very low frequency short, SLOW messages that, "boom" through the earth to a submerged submarine. Other, "FamilyGrams." Again, short messages that are conveyed on a regular basis between crew and (obviously) family at home - not really two-way either. Sub comes to a certain depth, trails out a wire, and transmission begins and ends RAPIDLY! In short, without coming to the surface, there's no two-way communication. They did try something in 2008 that allowed duplex, but it had something to do with a floating transponder. I've no idea what happened to that, but, I keep thinking of one of the major reasons, "shnorkels" failed, then consider what modern tracking devices can do...and shudder.
Let's be fair here, folks! There's nothing inherently wrong with having an iPod on a sub - as long as one's not using it while on duty!
