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?
