I'm unable to send MMS/group texts in my Galaxy S20 unless mobile data is turned on.
2 days ago, I sent these types of messages from both and LGG4 and a Galaxy S6 with no issues. Wifi on, mobile data off.
I've had sprint reprovision my device twice and have factory reset the phone to no avail. I know this functionaly exists, because I've done it for years.
Being as the function worked 3 days ago on the same carrier with 2 different Android devices, one of which was a galaxy series, I'm going to assume this functionality exists.
I feel this is an issue or change with the latest series of galaxy devices.
I've seen similar posts on the S10s and other models. Something changed.
This seems to work, but I didn't have to have wifi calling enabled on my old devices. So again, there's been an unnecessary software change somewhere preventing this.
There has to be another fix to get things back to where they've been for years.
