Yes, the Xiaomi 15 Ultra supports data acceleration and dual WLAN acceleration. And it allows you to use Wi-Fi and hotspots simultaneously, providing greater flexibility in managing your network connections.
Multi-network parallel acceleration is a feature designed to improve internet connectivity by combining multiple networks (such as 4G, 5G, and Wi-Fi) to provide faster data transfer speeds and more reliable connections. This technology allows the phone to seamlessly switch between networks or use them simultaneously to optimize performance, particularly in areas with weak or fluctuating network signals.
