Hi Marcus,

This board requires LTE CAT m1, which is currently only offered by Telstra on B28. This band is not supported by this board. If you want to use the LTE features of this board then you should get the SIM7000E which includes B28 and has been confirmed to work with Telstra wherever there is LTE coverage.
