Data connection XOR MMS

Hello,

Here is my device : Samsung S9 Plus with 0.7-o-2019082020897-stable-star2lte.

I have spent a lot of time to find a workaround in several ways, but I finally abandonned :'(

The issue is that I am not able to send MMS using the Internet APN. To be able to send MMS, I had to add "default" to the APN type attribute so I can select the MMS APN. Then, I am able to send or receive MMS, but of course, not to connect to Internet (to do this, I have to share my data connection with another phone).

I know that this is a common issue, but could you please tell me if you are working on it, and when you are supposed to deliver the patch ? ...Or if it is already published ?

I have checked my configuration with several people or phones where it works properly, all is correct.

I am in France (Orange through the virtual operator NRJ) and have been in Germany the previous days ; the issue was quite the same with Proximus.

Many thanks for your help !

Eric
