FAQ
Why won't my phone connect to WiFi?
WiFi connection issues are usually caused by network interference, incorrect password, or outdated drivers. Try forgetting the network and reconnecting, or restart your router.
How do I fix mobile data not working?
First check if mobile data is enabled in Settings → Connections. Then toggle airplane mode on and off. If that doesn't work, reset network settings in Settings → General Management → Reset.
What's the difference between WiFi and mobile data?
WiFi connects to your home/public networks for free data, while mobile data uses your carrier's network. WiFi is faster and doesn't count toward data limits.
