I used the social media internet package on Elation in June, and I was able to communicate to everyone via facebook messenger and imessage no problem. I did not try video calls, but I believe audio calls are just fine. I have read that whatsapp works the same. This will only work on the ship though. If you need to use your phone in the ports, AT&T has international day pass for $10/day. I will have social media internet on my next cruise, and I plan to use the day pass if needed in the ports (mostly just to be able to use Maps).
