  ZTE (USB 3G Modem)
  Mint (older version)
  Works fine with some minor problems
What works:

Able to connect to a provider

What doesn't work:

I used wvdial workaround to get the modem to connect to internet. It is a bit success, but, even though it is connected, internet cannot be accessed. I have tried redialing multiple times and using other workarounds such as setup the networkmanager, which also unable to solve the problem.

This problem happened on MATE and Cinnamon editions, both 32-bit and 64-bit.

What was done to make it work:

It seems that there is a bug in Linux Mint 13 (both Cinnamon and MATE) that prevents WvDial to work properly. A workaround for it to open terminal, and type
sudo dpkg-reconfigure resolvconf
Use WvDial and it should work properly now.

Thanks to Ihsan for the solution

Additional notes:

To use WvDial workaround, you need these five packages
libwvstreams (base)
libwvstreams (extra)
libuniconf
libxplc
wvdial

On Windows, download them from pkgs.org

After installing Linux Mint 13, install all of the packages with GDebi, then type these commands in terminal

lsusb
sudo eject /dev/sr1
sudo modprobe usbserial vendor=0x19d2 product=0xffdd
dmesg
sudo gedit /etc/wvdial.conf
sudo dpkg-reconfigure resolvconf
sudo gedit smart.sh
sudo chmod +x smart.sh
./smart.sh

After typing ./smart.sh in terminal, internet should be on. To disconnect, press Ctrl+C. If you want to use the internet again, open terminal and type ./smart.sh

When editing wvdial.conf, copy paste the text below
[Dialer smart]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1; &D2; +FCLASS=0
Modem = /dev/ttyUSB0
Modem Type = Analog Modem
Baud = 460800
ISDN = 0
New PPPD = yes
Stupid mode = 1
Command line = ATDT
Phone = #777
username = smart
password = smart

When editing smart.sh, copy paste the text below
#!/bin/bash
sudo eject /dev/sr1
sleep 2
sudo modprobe usbserial vendor=0x19d2 product=0xffdd
sleep 2
sudo wvdial default

However, Linux Mint's network manager won't recognize it, though you can still install updates and apps. If you do this before installing Linux Mint, the installer will still tell you that the computer is not connected to internet. This problem is minor though.

If you use this workaround, you need to register the modem with Windows first and you still need to have Windows to manage the internet bill, since WvDial cannot.
