Ever since my S25 arrived I have nothing but issues with the 2nd SIM. I have 1 X physical as main Sim and 1 X secondary Sim as eSIM. 

I already know about the issue where SIM 1 and SIM 2 are displayed in reverse order in the messages app. That still is not fixed with latest firmware Feb 8 2025 is pathetic. 

The major is that SIM 2 is always showing Emergency calls only. Occasionally it will obtain coverage, then it will loose connection and then go back to emergency calls only. It is a USA eSIM from Ultra mobile and had 0 issues with my S21 or my Motorola Neo 50 with this eSIM.

My is having same issue with her S25. She upgrade from S24 which had no issues with eSIM but major issues with S25. 

While roaming in Japan last week, I could not even enable this eSIM. I purchased a local Ubigi eSIM and it worked fine. 

I have seen a number of other users with 2nd SIM issues but no response from Samsung addressing even the most basic issue with the SIMs being reversed in the messages app.
