SIM900 friendly carriers - Australia


Sorry for the noob question (I have only just learning about  this stuff).

Have any of the Australian users here had any success using an ALDImobile SIM (carrier is Telstra) with SIM900?

I just got a SIM900 shield but when I put the ALDImobile SIM card in it the LEDs indicate the SIM cannot register to a network. The same SIM card works fine in a mobile handset.

Could this be a problem with the carrier? I.e. is it worth me trying a SIM from another provider?
