The two phones share a solid connectivity foundation — both support 5G, NFC, USB Type-C, GPS with Galileo, and an identical sensor suite including gyroscope, accelerometer, and compass. For the vast majority of everyday connectivity needs, they are functionally equivalent. The key divergences lie in Wi-Fi generation and SIM configuration.
Wi-Fi is where the gap is most technically significant. The Edge 60 Pro supports Wi-Fi 6E, which operates on the 6GHz band in addition to 2.4GHz and 5GHz. This translates to substantially lower congestion, higher throughput, and reduced latency in environments with many connected devices — a modern home, a busy office, or a public venue. The Y400 Pro tops out at Wi-Fi 5, which remains capable but misses out on the 6GHz band entirely and will show its age as Wi-Fi 6E infrastructure becomes more prevalent. On SIM flexibility, the trade goes the other way: the Y400 Pro accommodates two physical SIMs, while the Edge 60 Pro offers one physical SIM plus one eSIM — the latter being more convenient for international travellers who prefer digital switching, but less practical for users who rely on two active physical SIM cards simultaneously.
On balance, the Edge 60 Pro has the connectivity edge, primarily because Wi-Fi 6E is a forward-looking and practically impactful upgrade over Wi-Fi 5. The Y400 Pro's dual physical SIM support is a genuine advantage for a specific user segment, but it does not outweigh the broader wireless networking benefit the Edge 60 Pro brings.
