Telstra Air is a lifestyle app developed by Telstra Corporation Ltd. that allows users to access Australia's largest Wi-Fi network with over 1 million hotspots across the country and over 19 million Fon hotspots overseas. To take part in the service, users must have an eligible Telstra personal mobile or Telstra home broadband service and a compatible gateway.

With the Telstra Air app, users can easily connect to hotspots when they're out and about. The app automatically connects users to the Telstra Air Network when they are within range. One important thing to note is that Google Smart Lock is a service provided by Google, which allows users to store usernames and passwords, making it easier to log in without having to re-enter their credentials when using their Chrome and Android devices. If users choose to use Smart Lock, their use of it is subject to Google's Privacy Policy and Terms of Service, as well as its API Terms of Service.

Overall, Telstra Air is a useful app for Telstra users who want to stay connected to Wi-Fi while on the go. If you have an eligible Telstra service and compatible gateway, it's definitely worth checking out.
