Shared connectivity fundamentals — 5G, NFC, USB-C, GPS, gyroscope, accelerometer, and compass — are present on both phones, so neither leaves users short on everyday essentials. The divergence begins with cellular throughput: the Galaxy S25 FE supports download speeds up to 9,640 Mbits/s and uploads of 2,550 Mbits/s, roughly double the Galaxy A56 5G's 5,100 / 1,280 Mbits/s. In practical terms this gap only matters in areas with very dense, high-capacity 5G networks, but it does reflect the S25 FE's more advanced modem and positions it better for network infrastructure that continues to expand.
Wi-Fi and Bluetooth follow the same pattern. The S25 FE adds Wi-Fi 6E support, which opens access to the less congested 6 GHz band — a tangible benefit in dense environments like apartments or offices where the 5 GHz band is crowded. Its Bluetooth 5.4 is a minor step ahead of the A56's 5.3, with incremental improvements to connection reliability. One notable trade-off, however, is SIM flexibility: the A56 accommodates 2 physical SIMs and 2 eSIMs, making it significantly more appealing for frequent travelers or dual-SIM users, while the S25 FE is limited to 1 SIM and 1 eSIM. Additionally, the S25 FE includes a barometer — useful for altitude tracking and weather sensing — which the A56 lacks.
This group has no single winner. The S25 FE leads on raw wireless performance, Wi-Fi 6E, and sensor depth, but the A56 5G holds a clear practical advantage for anyone who depends on dual physical SIM support. The right choice here depends entirely on the user's specific connectivity priorities.
