I have been using Ubuntu during 20+ days. I am now using a 3G wireless modem (huawei e303-h1) to connect with internet. My modem's software is specially designed for Windows. So whenever I connect it in Windows I see a nice GUI which allows me to call, send sms, receive phone calls, monitor network speed and data etc. convenient features. I just want to know if I can install a software on Ubuntu for this modem to do same things that I can do in Windows. Is there any free open source software which can offer me such features?
You can install Modem Manager, which can fulfill some of your requirements. It is in Software Center, or can be installed by
It can send, receive SMS, USSD, monitor traffic, networks, etc.
But it can not make phone calls.
