My old Samsung S4 is getting a bit long in the tooth and I need to upgrade. I am happy with Android and Samsung so I think a basic Samsung Galaxy S9 (64gb) will suit my needs. I have noticed that the dual sim versions are a bit cheaper than the single sim version at around $900 if you shop around.

However I am getting mixed messages on the use of the second sim slot - some say you can put in a sd card up to 256gb and others so in theory yes but in reality no.

Now I do not need a second sim but I do want a sd card slot. The single sim with sd slot S9 is about $50 more expensive than the dual sim version so if the dual sim version can use use a sd card in the second sim slot that is great.

So will the dual sim version work Ok with an SD card in the second slot? And if so, any reason why the dual sim card version is cheaper than the single sim version? What am I missing?

Thanks
