Can MMS messages be sent/received over WiFi on IOS? In my experience yes and no; will this be fixed?

Hi all,

I have two iPhones on Xfinity Mobile. I do not use cellular data at all - only WiFi at home and work.

I have discovered that MMS messages (photo messages) cannot be sent or received while on WiFi. It appears that cellular data must be turned on to use MMS messages when using an iPhone. Android users, however, can use MMS messages with cellular data turned off.

I have also discoverd that there is a workaround for iPhone users: if you turn on "WiFi Calling", then you may be able to use MMS messages with ceullar data turned off. There is one caveat: after turning on WiFi Calling, you must then put your phone into airplane mode. With WiFi calling turned on and the iPhone in airplane mode, MMS messages work with only a WiFi connection. This workaround is inconvenient because airplane mode means that I cannot make or receive phone calls while away from a WiFi network.

My question to Xfinity Mobile is this: on an iPhone, is it possible to have cellular data turned off and still send/receive MMS messages while on the ceullar network (i.e, not in airplane mode)? If so, how can I make this happen? Currently, MMS messages will only send if I turn on WiFi Calling and am in airplane mode.
