This red SIM card tray is a dual-slot tray for the Vivo X21i. It takes two SIM cards, or one SIM card and a microSD card, so it suits both dual-SIM users and people who want extra storage.
How to tell it is the right tray for your Vivo X21i
Check that your phone is a Vivo X21i and that the tray is red. The tray is built for the Vivo X21i, so it sits flush in the slot and lines up with the phone’s edge once you slide it back in. The tray is listed as a SIM card tray with a second slot for a SIM or a Micro SD card.
- Phone model: Vivo X21i
- Colour: Red
- Slots: SIM + SIM, or SIM + Micro SD
Before you buy, make sure the tray you need has two slots. A single-SIM tray will not give you the second card slot you are after.
