Hi, I purchased the reServer i5 version. Currently I connect 5G modem through the M2 B-key. The modem is detected and correct driver is loaded. I can use the AT command. But when I inserted valid SIM card in the SIM slot, the SIM card is not detected. Is there anything I need to configure so that my SIM card is detected?
May I know if the reServer support / tested with any 5G modem? If so, please let me know what make and model are supported, thanks for any info!
Hi, I inserted the SIM card and reboot again, but the ‘SIM card not detected’ issue still exists. Also confirm the SIM card contact side is correct. Any other suggestion? Thank you!
(1) For the USB version, the OS did detect the modem (‘lsusb’ also listed the modem) and loaded the driver (e.g. ifconfig -a listed it as wwan0). However it failed to work, as it did not detect SIM card (was able to use AT Commands through /dev/ttyUSB1. AT+CPIN? returned “SIM not detected” message).
(2) The USB3 version was able to work with an external M.2 B-key => USB3 adaptor (with SIM slot on adaptor). SO for at least for USB version the OS configuration seems to be OK. Only SIM detection is the problem. SIM is inserted with contacts facing the PCB. SInce the slot is polarized it is not possible to insert any other way. Also we have tested with multiple SIM cards.
(3) For the PCIe version the OS failed to detect the hardware it self ('sudo lspci` didn’t report any new device!)
Any assistance appreciated!
Also if you can provide the 5G Modems that were successfully tested with reServer will be highly useful.
Not on the reserver but on the previous j4105 board I use Quectel RM500GL without any problems and fairly ok to work with, does SA mode and getting linkstats from AT interface and GPS is reliable as well since latest firmware.
With ref. to Sin Lam’s post above on the PCIe issue : Please provide details of configuration pins on the M.2 B key socket which specify the configurations that are supported. Are any specific settings/driver config (Linux kernel 5.15.x) needed to enable PCIe support?
Hi all, I use “Dell DW5811e Snapdragon X7 LTE 3P10Y Sierra EM7455 Qualcomm 4G WWAN Card Module”, and my re-server can detect the modem. However, the SIM card is not detected. I have tried a few other SIM cards and none is detected. May I know any way to troubleshoot it or the device has faulty SIM slot? Thanks for any info!
Has anyone solved this issue. I am having the same problem with the SIM card not being detected.

Okay. I am following up with myself.
I have solved my particular issue.
If you own a reServer, and decide to use the SIM card slot. Then be aware that you will insert the SIM backwards.
Meaning the flat edge goes in, and the angled edge will stick out from the board. This is opposite many 4G/5G modems that let you insert SIMs with a spring loaded mechanism.
I spent about 20hrs troubleshooting everything, until I figured this out. Now its working flawlessly with my EM7565
