Hi there, thanks for taking the available time out of your busy day to ask us your question about the Samsung Galaxy Tab S6 Lite. This Wi-Fi enabled tablet lacks the cellular connectivity needed in order to need to SIM card so, no, it does not have a SIM card tray. It does, however, have the capability to expand out the storage up to 1TB when you add a microSD card to this tablet! Let us know if you think of any other questions for us by contacting Samsung Support. Thank you for being a faithful Samsung customer. - Debra
