I was back in Vietnam for the last 3 weeks for my Tet holiday. Back there, my house does not have internet connection, luckily I've got a 3G USB device from my friend, which is  MF 190(ZTE). This device comes from Vinaphone - one of the Mobile phone service providers in Vietnam. As usual, this device does not come with linux driver, but after fighting with it for more than half a day, I was able to get it to work on my Archlinux x86_64 laptop. The reason why it took so long was that the signal at the place (my friend's cafe) was too low, I did not know that until I brought it outside.

All that is needed for the 3G USB  to works under Archlinux is usb_modeswitch (from community repo) and wvdial (from extra repo). After installing them, when you plug it in, you should see a GSM modem in dmesg. The rests are just wvdial configurarion.

This is my /etc/wvdial.conf

These settings are for Vinaphone 3G network only. Create the file and type:

Remember to replace "1234" in Init1 = AT+CPIN=1234 with your SIM card's PIN.

Then type:

$wvdial pin

$wvdial thenet 3gonly 384k

And that's it, you're already online.
