All amaysim mobile and data-only plans are powered by the Optus Mobile Network. If you’re using a 5G-enabled device and you’re within a 5G coverage area, you’ll be able to access 5G signal, otherwise your device will select the next strongest available signal in your area, which in most cases will be 4G.
Your coverage will depend on a range of factors, such as your device, its software, your proximity to a network tower and network traffic.
To check the coverage in your area, simply enter your address or post code into our handy coverage checker.
