-
Toggle Airplane Mode. Enable it for about 30 seconds, then disable it to reset your wireless connections and potentially fix the problem.
-
Disable Wi-Fi. Smartphones often prioritize Wi-Fi over mobile data, even with poor Wi-Fi connections.
-
Restart your Samsung device. A simple restart can resolve many connectivity issues.
-
Update your Samsung phone’s operating system. An important update may be required for network connectivity. Connect to Wi-Fi before updating.
