Samsung Galaxy S9 Dual Sim

Thanks Deano but not looking to use the second sim slot for a sim but a SD card.

Also would the latest dual sim Samsung Phone released in Australia not have a useable second sim spot - doubt it - maybe applies to older phones but not the latest product.

Don't know about other phones, but I have Optus and Telstra sims in the two slots on my OPPO and they both work here. The SD card also works.
