I think it may be new. I don't think it's tablet related bc it works for me on wifi-only when my tablet is off.This must be new or only tablet related because you've always had to have data enabled to be able to view MMS messages while on WiFi, with Verizon "Smartphones". (regardless of the messaging app you're using)
