Galaxy Z Flip 8 SM-F776U FCC Filing Confirms Satellite Connectivity

Samsung's upcoming clamshell foldable has cleared an important regulatory milestone in the United States. The Galaxy Z Flip 8 carrying model number SM-F776U has appeared in official FCC certification documents, confirming NB-NTN satellite connectivity alongside modern wireless standards and charging features.

Satellite Connectivity and Wireless Bands

According to FCC regulatory filings under FCC ID A3LSMF776U, the US carrier variant of the Galaxy Z Flip 8 supports NarrowBand Non-Terrestrial Network (NB-NTN) communication on Band 255. This hardware capability allows the handset to connect directly to orbital satellites for emergency messaging and basic data transmission when standard cellular towers are out of reach.

Alongside satellite support, the certification documents confirm tri-band Wi-Fi 7 connectivity, Bluetooth 5.4, NFC, and Ultra-Wideband features. Cellular radio testing lists broad 5G Sub-6 and mmWave band compatibility, covering n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n38, n41, n66, n71, n77, n78, n257, n258, n260, and n261 for major US networks.

Charging and SAR Certification Details

The FCC SAR and RF exposure reports also detail the charging capabilities and physical radio measurements for the SM-F776U. The device supports wireless charging as well as reverse wireless power sharing, allowing users to top up compatible accessories directly from the back of the phone.

Regulatory testing records a head SAR value of 1.09 W/kg and a body SAR value of 1.20 W/kg, with simultaneous transmission rated at 1.59 W/kg. DisplayPort video output over USB Type-C is also listed among the tested hardware functions.

Hardware Context and US Model Decoding

In Samsung's naming convention, the "U" suffix in SM-F776U designates the carrier-locked United States model, which pairs with the unlocked SM-F776U1 variant. While international models in select regions utilize Samsung's Exynos 2600 platform, the North American SM-F776U runs on Qualcomm's Snapdragon 8 Elite Gen 5 chipset paired with 12GB of RAM.

The handset retains a compact folding footprint with a 6.9-inch Dynamic LTPO AMOLED 2X main screen and a 4.1-inch Super AMOLED cover display. Power comes from a 4300mAh battery supporting 25W wired charging.

What This Means for Buyers

For travelers, hikers, and commuters in rural areas across North America, built-in NB-NTN Band 255 support adds a reliable safety net without requiring bulky external satellite communicators. Combined with full US mmWave 5G bands and Wi-Fi 7, the SM-F776U delivers complete network readiness out of the box.
