Zanzanz Galaxy Tab A 8.4 SIM and Micro SD Card Tray

The Zanzanz SIM Card Tray is a single-purpose replacement part aimed at owners of the Samsung Galaxy Tab A 8.4 from 2020, identified by the model number SM-T307U. Rather than an accessory that adds capability, it restores capability that was lost when the original tray went missing or failed. The design pairs a SIM card slot with a Micro SD card slot on one black tray, matching the combined layout Samsung built into this tablet.

What distinguishes this part is its narrow, model-specific fit. Trays are keyed to a device's exact opening, and a component listed for the SM-T307U is cut to align with that housing rather than approximating a universal shape. For a buyer, that means the practical work is verification: confirm the tablet reads SM-T307U, then match the tray. The black coloring is chosen to sit flush with the device edge, so a correctly seated replacement looks like factory hardware. Because the listing focuses on fit and function rather than materials or included tools, anyone planning the swap should be prepared to supply their own ejector pin and handle the small tray carefully during insertion.
