Since owning my iphone X, I've only ever sent two animoji's, on the first occasion to my wifes iphone 6, both handsets were in the house connected to wifi, but I got billed for it through my carrier. On the second occasion I sent a couple of Animoji's to my mates iphone X and I also got charged for it. The charges on my bill for both occasions said MMS messages, I am on the EE network and in the U.K. I thought Animoji's were free to send via iMessages to any iphones as long as you're connected to the wifi/data? I checked the messages app and the messages are showing up in blue colour, that means they are part of iMessage and have not been sent through my carrier. Not sure I want to send anymore animoji's if I keep getting charged for them, do I need to do anything in the settings maybe?
