What is Telstra 4GX USB Pro?

The Telstra 4GX USB Pro is a device that plugs in to your Telstra Business Smart Modem. If there’s an issue with your nbn™ connection, it provides you with a backup phone and internet service using Telstra’s 4G mobile network.

The Telstra 4GX USB Pro is also handy when waiting for your nbn service to be activated, as you can use it as an interim solution in the meantime.
