Salutations, thanks for taking the opportunity to ask us your question about the Samsung Galaxy Tab A9+. The advertised Galaxy Tab A9+ is a Bluetooth and Wi-Fi connected device. It does not offer a SIM card tray; however, it is fully functional while in the presence of a steady Wi-Fi signal. If you have any other questions, do not hesitate to reach out to Support. Thanks for being a devoted Samsung customer. - Debra
