MMC with Sim Card Reader for Asus Zenfone 2 Deluxe ZE551ML

The MMC with SIM Card Reader on your Asus Zenfone 2 Deluxe Ze551Ml is the physical card reader module — the assembly of contact springs and housing that makes electrical contact with the SIM card and microSD card when they are inserted into the tray slot. It includes the spring contact array for both card types and the housing that guides the tray into the correct position for reliable reading on your Asus Zenfone 2 Deluxe Ze551Ml.

The MMC with SIM Card Reader is the physical contact mechanism — the spring contacts that touch the card's gold pads when the tray is inserted. The MMC + SIM Connector is the surface-mounted board connector that the card reader connects to on the motherboard. Both must be functional for card detection to work on your Asus Zenfone 2 Deluxe Ze551Ml. This listing covers the physical reader assembly — not the board connector.

Replace it when the contact springs are visibly bent, corroded, or broken — causing intermittent or failed card detection despite using confirmed-working SIM and memory cards and a correctly fitting tray on your Asus Zenfone 2 Deluxe Ze551Ml.

It is a moderate repair requiring the phone to be opened. The card reader assembly is typically soldered or press-fit onto the motherboard or sub-board of your Asus Zenfone 2 Deluxe Ze551Ml. Professional tools and experience are recommended for clean removal and installation.
