I recently upgraded from Tata Photon+ to Tata Docomo Photon 3G, however Ubuntu is not recognizing the device itself. I tried manually adding the device in Mobile Broadband section, using different APNs and Service provider names as suggested in few earlier questions. The device is ZTE MF 190 (hsupa). What do i do?
Use sakis3g script
Sakis3G is a tweaked shell script which is supposed to work out-of-the-box for establishing a 3G connection with any combination of modem or operator.
It automatically setups your USB or Bluetooth™ modem, and may even detect operator settings.
It may work for you.
For details on sakis3g installation please refer to official Github page of sakis3g
For details on how to use sakis3g refer the official page
see this post for additional reference.
First you have to make sure the device is recognized as a modem and the proper
ttyACM are created.
dmesg output after the device is plugged in.
Most 3G modems start their life as a cdrom device, and it is the job of
usbmodeswitch to send the right command to bring the modem up.
I had the same problem,but then i checked. You just need to plug-in your dongle and select the Docomo network in networks section. It will works fine. If it doesn't then try installing mobile broadband drivers. Ubuntu should detect them automatically. If not,try downloading from internet
