cdflasdkesalkjfkdfkjsdajfd I used a Pixel 7 with GOS installed on it for most of the year 2023. With this Pixel 7 I was never able to keep two eSIMs active at the same time. I was, however, able to use one eSIM and one pSIM at once.
This of course might have changed in the past few months but that was my experience.
