These are the freq available on different Australian mobile networks
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
900Mhz (Telstra, Optus & Vodafone)
1800Mhz (Telstra, Optus & Vodafone)
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
850MHz (Telstra, Vodafone) – Exclusive 3G band
900MHz (Optus, Vodafone) – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
Australia is currently using these LTE bands (LTE bandmask in brackets):
2100Mhz (B1) FDD (0000000000000001) – Telstra (3G spectrum)
1800Mhz (B3) FDD (0000000000000004) – Telstra, Optus, Vodafone
900Mhz (B8) FDD (0000000000000080) – Telstra, Vodafone?, Optus (utilises spectrum previously used by 2G)
2300Mhz (B40) TDD (0000008000000000) – Optus (Vivid wireless spectrum)
To follow late 2014:
2600Mhz (B7) FDD (0000000000000040) – Telstra, Optus, TPG?
700Mhz (B28) FDD (0000000008000000) – Telstra, Optus
This is what the F240 Optimus G Pro supports.

So looks likes optus is the best bet for anyone wanting a F240
However I cant get any sim to detect so it must be a hardware faults, any good way to test hardware?
