At the core, these two phones share a strong connectivity foundation — 5G, Wi-Fi 7, Bluetooth 5.4, USB-C 3.2, NFC, and identical upload speeds of 3,500 Mbits/s. For everyday use, that common ground covers the vast majority of what users need. The divergences, however, consistently favor the Samsung Galaxy S25 Edge. Its peak download speed reaches 10,000 Mbits/s, double the Aquos R10's 5,000 Mbits/s ceiling — a gap that matters in dense 5G environments or when pulling large files quickly. The S25 Edge also adds Wi-Fi 6E support, extending Wi-Fi into the less congested 6 GHz band for improved speeds and lower latency in crowded areas, a standard the Aquos R10 does not support.
SIM flexibility is another meaningful point of separation. The S25 Edge accommodates 2 physical SIMs plus 2 eSIMs, offering exceptional flexibility for travelers or dual-line users who want to mix carriers without physical swaps. The Aquos R10 supports 2 physical SIMs only, with no eSIM capability. Flipping the advantage, the Aquos R10 includes an external memory slot — the only device of the two that allows storage expansion — while the S25 Edge is limited to its built-in storage. The S25 Edge also carries a barometer and ANT+ support (useful for fitness accessories like heart rate straps and cycling sensors), neither of which the Aquos R10 offers.
The Samsung Galaxy S25 Edge holds a clear overall advantage in this category. Its faster download speeds, Wi-Fi 6E, dual eSIM support, barometer, and ANT+ compatibility collectively represent a broader and more future-ready connectivity package. The Aquos R10's expandable storage is a useful perk, but it is a single feature against several meaningful deficits.
