Do I talk to the controllers when crossing the Atlantic Ocean?

Hey guys, I’m new to the VATSIM forum, and I have done a lot of flights on VATSIM (especially with Airbus planes). But anyways when I am crossing over the Atlantic, I learned that you have to submit CPDLC clearance to cross the ocean. But it got me questioning, do you talk to the controllers after when you submit your CPDLC Clearence? Let me know, so I can actually do it right next time I cross the Atlantic

Thank You!

It can be done by voice, text or CPDLC.

Ok, but after when you submit the CPDLC Clearence do you then not talk to them or talk to them once you get sent to that frequency?

You may need to give a position report unless they are simulating ADS-C.
