Mobile Broadband (MBB) is a portable internet service that operates off mobile towers and networks, such as Telstra and Optus.
Southern Phone provides these services in the form of a sim card that can be used in a USB dongle, compatible router and personal devices such as a smartphone or tablet.
Southern Phone uses the Telstra & Optus 4G network for its data coverage.
Southern Phone does offer a Mobile Broadband Dongle that operates on any 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.
