One UI 8.5 Introduces Multi-SIM Management for US Galaxy Users
Samsung is set to roll out its One UI 8.5 update, which promises to bring a much-needed feature to Galaxy phones in the United States: granular multi-SIM management. While international Galaxy users have long enjoyed the ability to assign specific SIM cards for calls, texts, and data, this functionality has been notably absent in the US market. With One UI 8.5, that gap appears to be closing, allowing American users to customise their SIM preferences similarly to their international counterparts.
Key Features and Early Impressions
The update, currently in beta for the Galaxy S25 series, enables users to designate which SIM card to use for phone calls, text messages, and cellular data independently. This level of control is particularly useful for those who juggle personal and work numbers or travel frequently. A Reddit user known as slylte, a US Mobile subscriber, shared screenshots from the One UI 8.5 beta running on the Galaxy S25 Ultra, showcasing the new settings interface and how users can select their preferred SIM for each function.
Context and Samsung’s Strategy
Multi-SIM usage has traditionally been more prevalent outside the US, where consumers often need to switch between carriers or plans for better coverage or pricing. Samsung’s omission of these detailed SIM controls in the US has been a notable oversight given the growing popularity of dual SIM phones. The One UI 8.5 update marks a strategic move to align the US Galaxy experience with international standards. So far, the beta is exclusive to the S25 series, but it is expected that Samsung’s 2025 foldable models will receive similar updates in due course.
Looking Ahead
Samsung’s upcoming Galaxy Unpacked event, where the Galaxy S26 series and Galaxy Buds 4 are anticipated to debut, will likely coincide with the official launch of One UI 8.5. Following this, the update should gradually become available to existing Galaxy devices beyond the beta participants. For US users who have been frustrated by limited multi-SIM options, this update offers a promising solution that brings greater flexibility and control over their mobile connectivity.
Keep an eye out for the One UI 8.5 rollout in the coming weeks as Samsung continues to enhance its software experience across its flagship devices.
