The tech world is buzzing with anticipation as three members of Samsung’s highly anticipated Galaxy S25 series have officially received their FCC (Federal Communications Commission) certifications. This regulatory nod signifies that the official launch is drawing ever closer, but a curious omission has left many scratching their heads. While the Galaxy S25, S25+, and S25 Ultra have all been confirmed, the rumored Galaxy S25 Slim is notably absent from the certification list.
The FCC filings, which identify devices by their model numbers, list the SM-S931B/DS, SM-S936B/DS, and SM-S938B/DS. These model numbers follow the established Samsung naming convention, neatly aligning with the Galaxy S24, S24+, and S24 Ultra respectively. The ‘B’ designation indicates an international version, while ‘DS’ signifies dual-SIM capability. This pattern strongly suggests that these are indeed the upcoming flagship devices.
However, the absence of a model number corresponding to the previously leaked Galaxy S25 Slim (rumored to be SM-S937B/DS) has fueled speculation. This missing model perfectly slots into the numerical sequence, further supporting its existence. The question is: why the omission from this FCC certification round?
Several possibilities exist. Samsung might be strategically holding back the Slim model’s certification to maintain secrecy before the official unveiling. Alternatively, the Galaxy S25 Slim might not be destined for an international release, or there might be unforeseen delays impacting its production schedule. Until Samsung clarifies, the mystery remains.
Beyond the Slim model intrigue, the FCC records provide additional insights into the Galaxy S25 lineup’s specifications. The standard Galaxy S25 and S25+ appear to retain their predecessors’ charging speeds: 25W wired and wireless charging. While the Galaxy S25 Ultra’s charging details are not explicitly stated, it’s widely expected to maintain the 45W system seen in the S24 Ultra.
As expected, all three international models are confirmed to feature NFC (Near Field Communication), Wi-Fi, and 5G connectivity. However, a significant anomaly has surfaced concerning Ultra Wideband (UWB) technology. While all three *international* Galaxy S25 models will include UWB support, the US version of the standard Galaxy S25 will notably lack this feature, as reported by Android Authority. This exclusion means US users of the base model will miss out on UWB-dependent features like digital car keys and precise location tracking with devices such as the Samsung SmartTag 2. To access UWB functionality in the US market, consumers will need to opt for the S25+ or S25 Ultra.
With the FCC certifications in place, the official unveiling of the Samsung Galaxy S25 series seems imminent. We anticipate a grand launch event, likely part of Samsung’s ‘Unpacked’ series, sometime in early 2025, where all the remaining mysteries surrounding the S25 lineup—including the fate of the S25 Slim—will be resolved.
