I am having a Thinkpad X1 carbon (5th gen) laptop with in build 4G mobile broad band modem. Even though the socket for the SIM card is available on the laptop, mmcli -L does not detect it. Is there some tool or patch I need to get installed in order to detect the modem. Please help. Thanks in advance.

See if your modem is on the list, if not, there's a hardware or driver problem:

If it is listed, ex:

Bus 001 Device 005: ID 0cf3:0036 Atheros Communications, Inc. 
Bus 001 Device 003: ID 0bda:58c2 Realtek Semiconductor Corp. 
Bus 001 Device 007: ID 12d1:14dc Huawei Technologies Co., Ltd. 
Bus 001 Device 002: ID 8087:8000 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Exec this command: sudo usb_modeswitch -v XXXX -p 1f01 -J

Replace XXXX with your device ID, ex: 12d1
