⚠️ Important notes:
Unlike older US models (S908U1/S906U1), S928U1 DOES support n77/n78 , so 5G works in most international locations.
China limitation: 4G perfect; 5G works but missing n79 (Chinese n79 band). Kimovil shows China Mobile 5G only 2/3 match . For optimal China 5G, China model S9280 is recommended.
Japan limitation: 4G perfect; 5G works but missing n79 (Japanese local 5G band). For optimal Japan 5G, Japanese model S928Q/SC-52E/SCG26 is recommended.
India Jio 5G: Hardware supports n28/n78, but Jio may not recognize the device as 5G-capable until bands are manually unlocked via service menu . 4G works perfectly regardless.
SIM configuration: Single Nano-SIM + eSIM. NOT dual physical SIMs. For dual physical SIMs, international version S928B/DS is needed.
Factory Unlocked, NO bloatware (XDA confirms U1 is clean unlocked )
📌 Best for: US buyers wanting full 5G (including mmWave); international buyers who want both 4G + 5G (S928U1 supports n77/n78, unlike older US Galaxy models)
