# Telstra Mobile - Data

Welcome to your new Telstra Mobile connection! The Telstra 4G and 5G Data Service provides high-speed mobile internet connectivity through Australia’s largest mobile network. It enables users to stay connected in areas where fixed-line broadband (such as NBN) may not be available or for redundancy. 

### **Setup Instructions**

**Step 1:** Insert the SIM Card into the SIM slot of your router or modem.

**Step 2: Configure the APN**

In your router’s web interface or device management panel:

* **APN:** `telstra.internet` 
* **Authentication:** None
* Authentication Protocol: IPoE/DHCP

*Note: Some devices automatically detect and apply Telstra’s APN settings.*

**Step 3: Verify the Connection**

* Check your device’s dashboard to confirm signal strength and connection status.

### Troubleshooting your Telstra 4G or 5G SIM <a href="#troubleshooting-your-nbn-tc4-service" id="troubleshooting-your-nbn-tc4-service"></a>

If you encounter issues with your Telstra Mobile connection, the problem typically falls into one of four categories: slow speeds/dropouts, or no connection.

{% tab title="No Connection" %}
If your connection isn’t working at all:

* Check the signal strength of the SIM on your modem/router. Ensure that the SIM is plugged and detected by the device.
* If the device doesn't have a signal, isolate for a potential hardware or SIM issue by testing on another modem/router or on a mobile. If there is still no detection, this could be a SIM issue and will require replacement. Otherwise, if there is a detection, it is then a hardware issue.
* Log in to your modem/router’s admin interface to verify if the service is obtaining an IP address with the connection
* If the service has signal strength, check the service in the partner portal to check for data consumption/usage to ensure that the Data limit is not reached.
  {% endtab %}

{% tab title="Slow Speeds/Dropouts" %}
Slow speeds or Dropouts can often result from high network usage or external factors such as signal strength. If speeds are significantly lower or service is experiencing dropouts:

* Restart your modem/router
* Check for a stronger signal strength location
* Isolate the hardware by using another modem/router or your phone
