Check a fresh connection on Wi-Fi and mobile data with guided network switching on your phone.
First turn mobile data off and connect to Wi-Fi. Run the request. Then turn Wi-Fi off, enable an active mobile-data plan and repeat.
The page measures fresh server responses after you confirm each switch. It cannot force the network type or diagnose antenna hardware from a failed request. This is not a download-speed test.
No location permission is needed. Your data plan and normal network charges apply.
Results are saved only in this browser for up to 24 hours. This single test does not replace a complete used-phone inspection.
