An impaired connection between the mobile device and the Telstra SIM card may cause issues with the cellular connectivity and the mobile data.

To address issues with the SIM card, it is advised to eject the chip, clean the SIM tray and reinsert it correctly into your Telstra mobile.

Here’s how to reinsert Telstra’s SIM card in easy steps:

1. First, find the SIM slot on the side of your Telstra mobile.

4. Update the Firmware of the Device

The next step is to update the firmware of your mobile device to gain access to the latest features and hotfixes.

Uploading the latest firmware available for your device is necessary to maintain proper functionality of all default features and settings, including mobile data.

How to Update Firmware On Android?

• To update, go to “Settings” → “Software Update” → “Start Update.”

How to Update Firmware On iOS?

• To update iOS, go to “Settings” → “General” → “Software Update” → “Install Update.”

Once the device finishes the firmware update, it will reboot to load the latest software data and functions.

You can enable “Automatic Updates” for both Android and iOS devices in the settings.

5. Apply Telstra’s APN Configuration

Not adjusting the APN configuration of your mobile device to Telstra’s details may disallow the usage of cellular functions, such as mobile data and cellular calling.

This step will provide you with the correct APN configuration released by the carrier to correct your device’s settings.

How to Set the APN Settings On Android & iOS?

• To set up the APN settings on an Android device, go to Settings → Wireless Connections → More → Mobile Networks → Access Point Names.

• To set up the APN settings on an iOS device, go to Settings → Cellular → Mobile Network → Mobile Data Options → New APN.

6. Check for Local Telstra Outages

There could be a local service outage with Telstra’s network, interrupting your device’s mobile data usage.

To determine if the current mobile status of Telstra is active and whether there are any outages, you must visit the provider’s outage page through a web browser on your device.

Here’s how to check for pending outages with the Telstra mobile service:

1. Navigate to Telstra’s Outage page and input your address.
2. Click on “Search,” and when prompted, sign into your account.
3. Check the current status of the Telstra mobile network below.

When there is a network outage, there is not much you can do but wait.

However, you can have peace of mind since the problem is not on your side.

Note: Remember that an outage or maintenance of the network may take up to 3 hours before it is resolved, so you must remain patient.

7. Reset the Mobile Network Settings

In case you’re still having issues with using Telstra’s provider mobile data, it is recommended to revert the network settings of your device to default.

So, restoring the default setup of the network settings is an effective method, but all Wi-Fi, Bluetooth and Cellular settings will be lost.

1. Open the Settings app on your Android device.
2. Enter the “Reset Settings” → “Network Reset.”
3. Confirm the reset by entering the device’s PIN.
