Checking the communication status (Network Visualizer)

The Network Visualizer app provides information on the direction of a communication connection, the communication speed of data transmissions, and the communication method. The following 4 types of communication methods are displayed: 5G mmWave, 5G sub6, 4G, and Wi-Fi.

You can visually check the communication status and see whether or not data transmissions have been interrupted while uploading or downloading. Even if the communication method switches to the next available network, the Network Visualizer app will continue to display the communication status.

Mobile data connection

  • To set mobile network options, find and tap [Settings] > [Network & internet] > [SIMs], and then select a SIM if you are using multiple SIMs.

  • Your device is set to automatically connect to the internet when you launch an app that needs an internet connection. (The setting may differ depending on your network operator.)

    If you are unable to connect to the internet automatically or if you are instructed to do so by your network operator, follow the setting procedure indicated by your network operator to set the access point to connect to the internet.

  • To set, check, or change the access point, find and tap [Settings] > [Network & internet] > [SIMs], select a SIM if you are using multiple SIMs, and then tap [Access Point Names]. If you change a setting by mistake, reset the settings.

Increasing Wi-Fi signal strength

There are a number of things you can do to improve Wi-Fi reception:

  • Move your device closer to the Wi-Fi access point.

  • Move the Wi-Fi access point away from any potential obstructions or interference.

  • Do not cover the Wi-Fi antenna area of your device.
