I have had my S20 since a little after release and am using an eSIM for data and a physical SIM for calls and text. When receiving an MMS on the physical sim I used to be able to download the pic/vid/voicemail no problem. Lately in the last few months it no longer lets me download the MMS unless I swap my data over to the physical SIM. I haven't changed any settings on my phone to think of and auto download is set. eSIM is Telstra and physical is Woolies.
Does anyone have any ideas to try out to fix this or has had it in the past?
Does it download if your turn on WiFi? Doesn't solve your problem but might confirm which sim is not cooperating? Are the APN settings for an eSim the same as a normal sim?
