# Internet connection setup

The most common ways to connect to the internet are to use mobile broadband on the controller or to use the controller's Wi-Fi radio. How to connect to the internet using these options are described below.

Alternatively, if the SIM card you want to use is in another device, you can connect the controller to the other device and use that device to connect to the internet. See:

- Internet setup using a separate smartphone
- Internet connection using another device

To use the internet connection for an internet RTK data link, in the data link page of the survey style, tap next to the GNSS internet source field and select Controller internet. See To configure a rover internet data link.

To use mobile broadband on the controller

To use the cellular modem and the SIM card in the controller to connect to a 3G or 4G mobile broadband network, make sure a SIM card is inserted in the controller. For information on how to do this, refer to the documentation for your Trimble controller.

If the controller is running Android and there is a SIM card inserted, the device automatically connects to the cellular network. If more than one SIM card is inserted in the controller, navigate to the operating system settings screen and search for SIM cards and then select your preferred SIM card.

If the controller is running Windows:

1. Swipe in from the right to display the Windows Action Center panel.
2. If the Cellular tile is gray, tap the tile to enable it. The tile changes to blue.
3. To configure options for the cellular connection, tap and hold the Cellular tile and select Go to Settings.
   1. To automatically connect to the cellular network whenever the controller is in range, select Let Windows manage this connection.

   2. Select whether Windows can automatically switch to the cellular network if the Wi-Fi connection is poor.

   For more information, refer to the documentation for your controller.
