For years, Galaxy users outside the United States have had something American users quietly envied: the ability to set different SIMs for calls, texts, and data independently. It sounds like a small thing until you actually need it, and then the absence is genuinely frustrating.
That gap is closing. With One UI 8.5, Samsung appears to be extending full dual-SIM configuration options to US users for the first time. Beta builds running on the Galaxy S25 series have already surfaced evidence of this, with at least one US Mobile subscriber on Reddit showing the new SIM management settings live on their S25 Ultra.
The timing makes sense. Dual-SIM usage in the US has been growing steadily, driven by eSIM support, carrier flexibility, and the increasing habit of keeping work and personal lines on one device. Samsung holding back these controls for American users never had a particularly strong justification, and the company is now catching up.
Right now, the One UI 8.5 beta is limited to the S25 series. Samsung’s 2025 foldables are expected to follow, and broader rollout to existing Galaxy devices should happen after the Galaxy S26 officially launches at the upcoming Unpacked event.
If you have been working around Samsung’s limited SIM settings with third-party solutions or simply living without the flexibility, the wait is nearly over. It is a quiet fix, but for anyone managing two lines on one phone, it is a meaningful one.
