I activated a factory unlocked S20 with Xfinity 3 days ago. It had a nice feature where any time I sent or received a picture through text message, the phone would automatically toggle mobile data on and off to send or receive it. A few Samsung updates later, this feature stopped working. Now any time I want to send or receive a picture message I have to manually turn data on and off. I don't have an unlimited plan so I can't let data on all the time. How do I get this feature back? Did one of the updates remove it or is it a setting somewhere on the device that I can't locate? I tried different settings but nothing seems to resolve the problem. I appreciate any help because it's driving me nuts. Thank you.
