Hey there Chris, thank you for finding the free time out of your busy day to ask us your question about the Samsung Galaxy Tab A9+. The advertised Galaxy Tab A9+ is a Wi-Fi enabled tablet that lacks the cellular capability needed in order to be added to a wireless carrier's network. You would be looking for an LTE/5G version of this tablet if you were wanting to add it to your wireless carrier's network and/or to be able to add a SIM card to the tablet. So, to ultimately answer your question, the advertised Galaxy Tab A9+ does not have a sim card slot. It does, however, have expandable storage up to 1TB so it will offer a microSD slot. I hope that helps answer your question and provides some guidance for you on finding the correct tablet to fit your needs. If you have any additional questions for us, do not hesitate to reach out to Samsung Support. Thank you for being a valued Samsung customer. - Debra
