Mobile Broadband (MBB) is a portable internet service that operates off mobile towers and networks, such as those operated by Optus and Telstra.

Southern Phone provides these services in the form of a SIM card that can be used in compatible USB dongles, routers and personal devices such as a smartphone or tablet.

Southern Phone mobile broadband plans are available on the Optus 4G mobile network, and on the Telstra mobile network in limited circumstances.

Southern Phone does offer a Mobile Broadband Dongle that operates on any compatible network. It is available for an outright purchase price of $99.00.

Speed can and will vary with MBB, at its best you can receive upwards of 20Mbps.

Fluctuations in the speed can be expected, especially around peak periods.
