What does general use mean? The context is the same. We are talking about an expeditionary submersible having constant and reliable communication with its support ship all the way to the bottom. This was the setup of Cameron’s dive and this was the setup of the ill-faited Titan mission.
The people lost lived on the support ship, and only boarded the submersible when they arrived right above the Titanic. There the crew from the support ship bolted the crew of the submersible in, and the support ship remained in position and in communication with them until they lost that link. Then they waited for a long time, and only when the submersible was overdue that is when they raised the alarm. The only reason why we did know that the submersible went missing is because those on the support ship raised the alarm.
> And for that there is no reliable technology yet.
You can say that, but you are wrong. Sound waves propagate very well. I think what you might be confused about is that military submarines do not communicate with the shore during operations. They remain silent because if they start to transmit everyone will know where they are. But that is not because there is no reliable technology for it. In fact they can just blast a loud sound wave out with their active sonar and everyone all around the ocean will hear them who cares to listen.
I'm not saying that it is easy. All I'm saying that it is perfectly within our capabilities if we want to.

Are you claiming that this is not possible?
