Unable to Send or Receive MMS over WiFi after Android 10 update.

Unable to Send or Receive MMS over WiFi after Android 10 update.

So here's the latest bug I am experiencing after my SG9 was upgraded to Android 10 OS. 

 

With this new OS, Calling Plus/WiFi calling was replaced by WiFi calling and voLTE.  All seemed to go smoothly with the upgrade until I noticed I am unable to send or receive MMS when connected to WiFi calling.  I get a "Data tethering connection" error notice.  I am using the native Samsung messaging app and I am able to send and receive all types of messages, SMS and MMS when I am using the 'Chat Messaging" feature,  However, when it defaults to regular messaging, I can send and receive just regular SMS texts and not MMS texts.  This only happens when I am connected to the WiFi calling feature and have NO mobile service.  It is only when I have a cellular signal my MMS messages go through.

 

I have gone thru all my settings and I have yet to come up with a solution.  Is there any knowledgeable super user that can help me?  My work area is such that it gets no cellular signal at all and I can only send or receive messages via WiFi.  Remember, this only started AFTER the upgrade to Android 10 and worked just fine with 9.

Sprint has written us off, there is no fix or one coming. It used to work under wifi-calling but since the switch to VOLTE, you have to have active cell coverage to send and receive MMS.

Yes it is, however the issue is THAT IT DIDN'T USED TO BE. Your implementation of VO-LTE broke it.

I wish VoLTE was the issue because that would be an easier fix, but this has been an issue for the Note 8, Note 9, S8, and S9 since November 2019.  The issue is under investigation.  Essentially, the devices are supposed to drop back to mobile to authenticate who you are and send/receive the MMS.  We are telling Samsung to make the protocol the same as you have post 9 series.  They say they have, yet only those 4 devices are affected. Before the 8 series and after the 9 series, one can send MMS over wifi.  The fight continues.

you should probably ask him why he believes the problem is what he said and what exactly his background is with Sprint aside from being the site manager

LOL...Wrong is such a strong word.  I will be sure to tell Samsung.  If you are having that issue on 4 different phones at the same location on the same wifi, the only thing I can immediately think of is the cell service is non-existent for the phone to drop down too to send/receive MMS.  I just tried only all those models from our phone room and they all were able to send MMS to each other while on wifi.

 

PM me your problem address and one of the phone numbers and I will check.
