I have connected the dongle to my laptop, it shows in network manager with my network provider name (tata docom), but can't connect to internet.

How can I fix this?

Writing in terminal lsusb command gives following output

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 19d2:0143 ZTE WCDMA Technologies MSM

Device: usb0 -----------------------------------------------------------------

Type: Mobile Broadband (GSM)

Driver: cdc_acm

State: disconnected

Default: no
