Using Mobile Internet/Data While Connected To A WiFi Network (IOS/Android)

When attempting to connect an external device like a SkyEcho2, a Stratux, or a PowerFLARM to your phone, you need to ensure that your phone is connected to the external device's Wi-Fi hotspot while also having internet access through 4G/5G mobile data.

It's important to note that this setup is independent of the SafeSky App itself and is instead a configuration specific to your phone's operating system. Below are some common ways to solve this connectivity issue. However, if these methods don't work for your device, please consult your device's user manual for further assistance, as the SafeSky team cannot provide support for individual device configurations.
