Unpopulated SIM card on back side of LTE EC25-AF Mini-PCIe PCB

Hello Quectel forum members,

I would like to make use of the unpopulated SIM card footprint on the back side of LTE EC25-AF Mini-PCIe module. We are using this modem in an embedded IoT application and our mainboard does not connect the SIM card signals of the Mini-PCIe connector.

Does anyone know the manufacturer/part-number of the unpopulated SIM card holder?

Many thanks,

hello christianhahn, thanks for your question on quectel forums
You can search this modle SIM card holder, thank you.

Hello Duncan,

Thank you for the prompt response. I have searched the web for “8MS1F-014XR” and could not find any results. I also searched sub-strings of this part number and nothing came up.

Is “8MS1F-014XR” perhaps an internal part-number and not a manufacturer part number? Who is the manufacturer? Or, perhaps an alternate part number?

Thank you very much,

hello there
You can search SCH4150604 SIM card holder, thank you.

Many thanks Duncan.
This is exactly what I was looking for.

Hello Christian. We have your same problem, but SCH4150604 seems to be a p/n from Vela which we can’t source directly. Did you find a suitable alternative from RS, Digikey or similar?
