None of the S21 Range have external memory slots for SD cards its just internal memory. The great news is that while the S21 does not feature an SD Card slot for extra external memory, it does come stock with 128GB of storage, and plenty of secure, and extensive cloud options if you do need any additional space. We hope this helps! ^DB at Samsung Support No card slot Yes####[['external memory', 'Product Configuration#Memory', 'positive'], ['space', 'Product Configuration#Memory', 'positive']]
