Have in mind that LTE in Australia on 700 MHz is different to the US on 700 MHz.
In the US you use band 12 (T-Mobile) and 17 (AT&T). In Australia and soon in Europe band 28 is used.
All of them are called 700 MHz, but have different uplink and downlink frequencies. So it's better to add the bands to this in the future.
