I own a Samsung Galaxy S23 Ultra and recently switched to an eSIM with the national vendor Vodafone Egypt.
When I travel abroad, I always get a data eSIM from Airalo, Numero, or Lufthansa Breeze, offering better data quotas than roaming.
My question is, since I need my Egyptian eSIM on for financial tracking and authorization and use the other eSIM for mobile internet, I used to do that when my national SIM was physical.
Now, when I try to switch one eSIM on, the other goes off, and vice versa. Is this a company restriction, or can the Galaxy S23 Ultra not run two eSIMs simultaneously?
You cannot activate 2 esims simultaneously in S23 ultra This is supported from S24 ultra This is a tricky situation and no one highlighted this when advertising the esim.
For your situation it better unfortunately to return back to physical sim vodafone.
بالنسبه للاي سيم هي هتنزل بتعاون رسمي بين سامسونج وشركات الاتصالات طبعا لو هي لسه ما اشتغلت عندك اما لو هي اشتغلت وفيها مشكله فانت تقدر ترجع لشركه الاتصالات فودافون او تقدر ترجع ليه سامسونج وهي تنزل لك سوفت وير

The trick here that the focus when advertising esim that the mobile can download several esims which is true but no one talks about how many can be working at the same time. In S22 and S23 one esim can work at a time which will deactivate physical SIM2.
Actually, the eSIM won't deactivate the physical SIM card, and an eSIM and SIM could be activated simultaneously without issue. I tried this option many times during my travels. The issue I had recently is that, after switching my main SIM with an eSIM, I noticed that only one eSIM could be active at a time. The local Vodafone representative told me it is because I activated the other travel eSIM while I was still in Egypt, but honestly, I don't think that was the issue.
I was talking if your device support 2 physical SIMs plus esim that when you turn on any esim it will switch off physical SIM2 (in S22 and S23). If your device supports one physical sim only plus esim then the esim will not switch off the main physical SIM1 but still you cannot switch on 2 esims at the same time (in S22 and S23) so if you tried to switch on esim2 it will switch off esim1 and vice versa (one esim can be switched on at a time). I hope i explained it well.
