How does Samsung S3 go online, does Samsung S3 support mobile 4G network

Dear Samsung users: If your phone shows that you are connected to a wireless network, but you still can't access the Internet, it is recommended that you:1

Turn off your phone, restart your router, and reconnect to your wireless network. 2.Confirm the transmission bandwidth of the router (the supported router supports 40 MHz, we recommend setting it to 20 MHz) and check whether the router network is normal.

3.Confirm that IP address filtering is set up in the router MAC address filtering. 4.

If you still can't access the Internet via Wi-Fi, we recommend that you try using a static IP address. Method: Settings - (Connect) - WLAN - Select a wireless hotspot - Show advanced options - Tick - Swipe down the screen - IP Settings - Static - IP address Gateway.

5.Connect to another router and try to taste. 6.

If the problem persists, it is recommended that you bring the purchase invoice, the three-guarantee certificate and the phone to the Samsung service center for testing. It is recommended that you make an "appointment to visit" repair application on Samsung's official website to enjoy priority repair service.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center where you made the appointment on time. Comments, suggestions, complaints, please click:

If your phone can't access the Internet, please try the following:

1.**The card needs to be activated for GPRS Internet service.

2.Make sure your phone data is turned on: Slide down the top curtain of the screen with your hand and turn "Mobile Data" to green.

4.Please try a different SIM card or try again at a different time period.

If the problem persists, it is recommended that you bring the purchase invoice, repair card and mobile phone to the local Samsung service center for professional engineers to help you test.

Hope it helps, I wish you a great time!
