To be absolutely shure, just open the box. As you used it already, region matches, at least.
If you run dmesg after a reboot you should see some messages there indicating that the modem is ready for use. If you do not, then that means either your firmware is missing a required kernel module, or perhaps the modem is not powered on. Sometimes a modem is powered up via a GPIO pin, and you will have to toggle that GPIO. If it is a Quectel EC25 modem in NDIS mode, then you probably cannot use ModemManager to control the modem, you will need to use something like comgt, so try luci-proto-ncm.
The modem seems not initialised as I don't see such a message in the dmesg logs.. I am building another firmware with the AT commands lets see if I can get the modem detected with them.. Moreover the modem used is
Folksy 3RN13
Please share me information about it if you have any... regarding which kernel module would be required to get it detected automatically etc
Do you see a USB bus in the kernel logs? You may be missing USB, which would preclude anything attached to the USB bus from being detected. Try adding kmod-usb kmod-usb2 kmod-usb2-pci and kmod-usb3, then add kmod-usb-serial-qualcomm, as this looks like it has a Qualcomm chip based on what I found online.
How about you post your dmesg output after a full boot to Pastebin then link it here.
Start from posting the result of cat /sys/kernel/debug/usb/devices
That way we can probably make it properly detected by OpenWrt, however I read about 'No SIM' issue that has nothing to do with OpenWrt.
Getting a better modem should be the right choice.
My modem in a WG 3526 is also not detected, also with the above mentioned
kmod-usb-blablabla modules. Expect in the original chinese firmware (19.01.11),
but it never transferred any data thru 4/3/2G network. Weird!!
I think its some fault in the modem firmware as i tried a Asus 4G-AC68U which
uses, from my view, a good made firmware.
But it also not transferred any data. It seems this asian devices do
not work in specific regions.
I have got the chinese firmware which I extracted before I flashed the device with the latest openwrt.. I am thinking now of comparing the firmwares as with the chinese firmware I could make the modem work with the AT commands but there was some weird problem with dnsmasq and I was unable to install dnsmasq-full because it was running lede and the feeds links were all useless ones.. So I though of the upgrade... but anyways if anyone has any Idea please share.. Thanks 
Hello,
I am suffering the same issue with the Folksy modem.
Unfortunately I did not keep the original Firmware
Is there a way to get it ? I would like to work on finding the module on it
Thanks
You don't need original firmware to find the modem.
Thanks !
I did not get that far ... I did not insert the SIM as I believed that the card was not recognised

It seems to me that it is a "Alcatel Onetouch L850"
isn't it ?
Your modem is recognized and cdc_ether driver is bound to some interface. Just find the ethX interface name and configure it. See TP-Link Archer C7 v5 with TELSEC TS-1K6 USB 4G Modem
Thanks,
Indeed, I missed the relevant part on the output from "dmesg"

Hi @AndrewZ the dmesg output doesnot have cdc_ether in mycase I am unable to detect the modem

usb 1-1.3: new high-speed USB device number 3 using ehci-platform
Here a device (your modem?) is detected and registered on the USB bus, but no driver claims it.
That looks like the first boot of a new install, did you install the cdc driver yet?
Start from posting the result of cat /sys/kernel/debug/usb/devices
Hi, I have the same problem as the org. poster. While reading the forum looking for a possible solution, I came across your comment. I've attached my dmesg output as well as opkg list & debug > usb > device output. The SIM card, ISP connection worked (out of the box) with (SimpleMobile/ T-Mobile network until I flashed the device.
Linux version 4.14.195 (builder@buildhost) (gcc version 7.5.0 (OpenWrt GCC 7.5.0 r11208-ce6496d796)) #0
I don't know if the 2 are related but I tried to install Modem Manager but it also failed. Reporting that GCC is not installed in $PATH
I also tried to update the kernel but I don't have enough storage to download the file. Thanks,... any help would be greatly appreciated....

lsusb -v could be a good idea, to see what PID and VID the devices have, and take it from there.
Looking good. Install kmod-usb-serial-option, kmod-usb-net-qmi-wwan and either modemanager or uqmi

Hey,
Try what bmork suggested first, it looks like everything is powered up, you are just missing the USB drivers for your modem: https://openwrt.org/docs/guide-user/network/wan/wwan/modemmanager#kernel_modules
What version of OpenWrt are you running? Based on the kernel version it looks like you are on an older version of OpenWrt. If you install 19.07 you can install these packages via opkg instead of compiling them yourself. Moreover, if you install a master snapshot you can install luci-proto-modemmanager from opkg as well.
