Samsung Galaxy users in the US are about to get something international fans have enjoyed for years: proper, granular dual SIM management baked right into One UI.

The debate started on Reddit, where user slylte shared screenshots running the One UI 8.5 Beta on their Galaxy S25 Ultra.

As a US Mobile subscriber, the Samsung smartphone user showed off the new dual SIM preference options in all their glory, letting you toggle which SIM handles calls, which one takes messages, and which one carries your data.

International Galaxy users have had these settings for ages. The US market got left behind, and US carriers were almost certainly the blockage.

Carrier influence over software features is nothing new, and Samsung has historically played ball. With multi-SIM use slowly gaining traction stateside, that arrangement needed to change.

Once stable rollouts begin post-Unpacked, existing Galaxy owners outside the Beta Program should start seeing the update hit their devices. If you have been fighting with the lack of proper SIM controls, the wait is almost over.

Recently, Samsung pushed the fifth One UI 8.5 Beta update. While users are anticipating the official rollout next, the company has started internal testing of the sixth Beta. It should be available to S26 series phones early next month.

One UI 8.5 is shaping up to be the most significant upgrade yet. Based on the foundation of One UI 8, the upcoming mid-cycle iteration is not just a feature and design refresh, but also addressing long overdue complaints.
