Fibocom L860 GL on GL-SFT1200

I saw that L860 modem is supported by GLiNet modems (ROOter by Of Modems and Men )
How ever, router only see carrier name and did not connect to internet. I updated modem firmware to 18600.5001. but no luck. Model name and Imei are not displayed on UI, however i could see imei from AT Command

SFT1200 is not supported by ROOter.

ROOter has extra drivers included.
