It depends. From the specs listed on Samsung official website, we know there are two models, Single SIM model and Dual SIM model.
Single SIM model: one Nano SIM and one MicroSD slot (up to 512GB)
Dual SIM model (Hybrid SIM slot): one Nano SIM and one Nano SIM or one MicroSD slot (up to 512GB)
Samsung Galaxy S9’s Hybrid Card Slot
Availability of Dual SIM may vary depending on country and carrier. If you have two SIM cards, one for work while another for private communication, or two cards from two different operators. Choose the Dual SIM model, which supports dual Nano SIM and dual standby. And both two slots can be the main SIM card slot. You can switch following your need.
Does Samsung Galaxy S10/ S10 Plus/ S10E have a MicroSD slot?
Although Samsung released several models of different internal storage, we all know that more storage equals to a more expensive price. The good news is that all the versions have microSD card slots, so you can get up to 512GB extra storage.
However, if you choose a dual SIM model, you may have to make a hard decision. Realized by Hybrid SIM slot, it means you can place two SIM cards, or one SIM card and one micro SD card. If you want to place two SIM cards, sorry to tell you that there is no place for the storage card. It might mean that you have to pick up a higher memory model.

I purchased the unlocked version because I wanted support for dual sim. Unfortunately, Samsung does not ship the dual sim version to purchasers in the United States even if it is unlocked. Only the unlocked international version supports dual sim.

There is a major issue with S10 Dual sim version.The SIM management software does not work well.With both SIM cards inserted the keypad shows two call buttons even if you have set a preference for one of the two SIMs. If you want to see only one call icon on the keypad you need to turn off the second SIM!
