Hy, I tried to install an 4g connection. My card is detected but not the sim card. I test the sim card in a smartphone: it works. I test the wwan card in a router : can see the sim card. I put the card in the mcpie 1. I have only 1 sim slot. ```auto # lsusb -t /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 480M |__ Port 1: Dev 2, If 0, Class=Vendor Specific Class, Driver=option, 480M |__ Port 1: Dev 2, If 1, Class=Vendor Specific Class, Driver=option, 480M |__ Port 1: Dev 2, If 2, Class=Vendor Specific Class, Driver=option, 480M |__ Port 1: Dev 2, If 3, Class=Vendor Specific Class, Driver=option, 480M |__ Port 1: Dev 2, If 4, Class=Vendor Specific Class, Driver=qmi_wwan, 480M # ``` > # lsmod > > Module Size Used by > qmi\_wwan 32768 0 > usbnet 36864 1 qmi\_wwan > tag\_dsa 16384 1 > ath10k\_pci 45056 0 > ath10k\_core 397312 1 ath10k\_pci > mac80211 737280 1 ath10k\_core > mv88e6xxx 155648 0 > dsa\_core 118784 2 tag\_dsa,mv88e6xxx > libarc4 16384 1 mac80211 > bridge 286720 3 tag\_dsa,mv88e6xxx,dsa\_core > ath 36864 1 ath10k\_core > crct10dif\_ce 16384 1 > stp 16384 1 bridge > llc 16384 2 bridge,stp > omap\_rng 16384 0 > rng\_core 20480 2 omap\_rng > ipv6 462848 31 bridge > cfg80211 434176 3 ath,mac80211,ath10k\_core > > # mmcli --modem=1 > > * * * > > ## General | path: /org/freedesktop/ModemManager1/Modem/1 | device id: 2eba33c43fc3796f271732d5951b6df3c393f814 > > ## Hardware | manufacturer: Quectel | model: EC25 | firmware revision: EC25EFAR06A04M4G | supported: gsm-umts, lte | current: gsm-umts, lte | equipment id: 862348057941163 > > ## System | device: /sys/devices/platform/cp0/cp0:config-space@f2000000/f2500000.usb/usb1/1-1 | drivers: option, qmi\_wwan | plugin: quectel | primary port: ttyUSB2 | ports: ttyUSB0 (qcdm), ttyUSB1 (gps), ttyUSB2 (at), ttyUSB3 (at) > > ## Status | state: failed | failed reason: sim-missing | power state: on | signal quality: 0% (cached) > > ## Modes | supported: allowed: 2g, 3g, 4g; preferred: none | current: allowed: any; preferred: none > > IP | supported: ipv4, ipv6, ipv4v6 > > # In the diagramm, there is a microsim slot, but on my card i have only a normal slim slot . come the problem from it?

Check out my thread on the topic: [Clearfog Pro - MPCIE LTE Card (Quectel EC25) Not Detected](https://community.solid-run.com/t/clearfog-pro-mpcie-lte-card-quectel-ec25-not-detected/400/1) The TLDR is: 1. The EC25 uses USB, and the mPCIE slot with sim (near SOC) is not connected to usb. The sim slot you are using applies ONLY to the mPCIE slot closest to the SOC. 2. The far mPCIE slot supports USB, but the SIM slot does not come soldered to the clearfog board. You need to solder a holder to the board or use a mPCIE sim adapter. Details are in my thread. ---

Hy again ^^ Hope that my Question will not be silly but : If i undersrood well : -Slot mpcie closer sim slot is linked to sim slot,without USB connection. -Slot mpcie further sim slot has the USB connection. So, the lte/4g card must be installed in the slot mpcie further sim slot(to use USB connection). Is the USB connection hardware or can be attributed to the other slot mpcie thanks to the dts? ---

My phrasing was a little confusing. Your interpretation is correct. Unfortunately, it’s a hardware shortcoming - they simply didn’t connect the pins to the SOM. So, yes, you need to use the far slot, but there is no attached SIM holder. You gotta solder one to the bottom of the board or use an expansion card with a sim slot. I’m using this one, until I get around to soldering the holder: > **[Mini PCI-E Adapter with SIM Card Slot](https://www.amazon.com/Mini-PCI-Adapter-Card-Slot/dp/B07TJMV25K)** > > Buy Mini PCI-E Adapter with SIM Card Slot at Amazon. Customer reviews and photos may be available to help you make the right purchase decision! It’s a few mm too long, but you can still close the case. ---
