Dibawah ini adalah yang saya lakukan untuk terkoneksi ke internet dengan menggunakan layanan mobi dan sistem operasi linux (dalam hal ini saya menggunakan ubuntu intrepid ibex).

azil@arp:~$ sudo su -

Editing `/etc/wvdial.conf’.

Found an USB modem on /dev/ttyACM0.
Modem configuration written to /etc/wvdial.conf.
ttyACM0<Info>: Speed 460800; init “ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0″
root@arp:~# cat /etc/wvdial.conf

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
; Phone = <Target Phone Number>
ISDN = 0
; Username = <Your Login Name>
Init1 = ATZ
; Password = <Your Password>
Modem = /dev/ttyACM0
Baud = 460800

root@arp:~# vi /etc/wvdial.conf

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
Phone = #777
ISDN = 0
Username = username@evdo.mobile-8.net
Init1 = ATZ
Password = password
Modem = /dev/ttyACM0
Baud = 460800

Setelah selesai, coba dial dengan menggunakan perintah

azil@arp:~$ sudo wvdial
[sudo] password for azil:
–> WvDial: Internet dialer version 1.60

Setelah terkoneksi, test kecepatannya dengan bantuan speedtest.net

Selesai, mudah dan tidak repot. Selamat berkarya!
