Not if there is a picocell on board - that’s one of the major points of the article, including the EU mandating their installing on flights in Europe to enable people to connect.

However I agree with the airlines that lobbied in the US against this. It’s going to be a source of air rage - people crammed in a small space do not want to listen to other people yapping loudly on cell phones or video calls. It’s simpler to just ban it outright. Although I am sure the airlines also don’t want to have to pay for data connections and their air staff be responsible for dealing with irate customers when the connection is out.

But airlines have already started monetising things by making WiFi available on board flights for a fee - that is already opening the door to calls. I suspect we’ll end up with it as standard and a fight against exorbitant charges for connecting imposed by airlines.
