This HOW TO aims to help connecting the Aiko 83D modem (a.k.a. ZTE MF626) on Ubuntu for usage with operator Vivo (Brazil). Tested version: Ubuntu Desktop Karmic.
Note: At the appropriate stages of this article, specific reference to the operator Vivo is done so that the reader is able to adapt this solution to his/her needs.
To start, install usb-modeswitch so that the modem is not recognized as an USB storage device when plugged to the USB port:
Code:
sudo apt-get install usb-modeswitch
Next, configure usb-modeswitch. First, edit the ZTE MF626 configuration on the file usb_modeswitch.conf to reflect the needed changes for the operator Vivo (TargetProduct):
Code:
sudo gedit /etc/usb_modeswitch.conf
Code:

Second, create a file with the below code. Again, note the code “0x0057”, which is a match for Vivo.
Code:
Sudo gedit /usr/share/hal/fdi/information/20thirdparty/20-zte-mf626.fdi
Code:
<!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<device>
<!-- ZTE MF626 HSDPA USB Modem -->
<match key="@info.parent:usb.vendor_id" int="0x19d2">
<match key="@info.parent:usb.product_id" int="0x0057">
<match key="@info.parent:usb.interface.number" int="3">
<append key="modem.command_sets" type="strlist">GSM-07.07</append>
<append key="modem.command_sets" type="strlist">GSM-07.05</append>
<append key="info.capabilities" type="strlist">modem</append>
</match>
</match>
</match>
</device>
</deviceinfo>
Lastly, create rules for the computer to automatically switch on the modem when it is connected to an USB port. Note that this code is independent to the chosen operator:
Code:
sudo gedit /etc/udev/rules.d/90-zte.rules
Code:
ACTION!="add", GOTO="ZTE_End"
SUBSYSTEM=="usb", SYSFS{idProduct}=="2000", SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD"
LABEL="ZTE_ZeroCD"
RUN+="/usr/sbin/usb_modeswitch -W -c /etc/usb_modeswitch.conf"
LABEL="ZTE_End"
Now that usb-modeswitch is installed, it is time to install and configure wvdial:
Code:
sudo apt-get install wvdial
Next, edit wvdial.conf to create the specific dial-in for the modem:
Code:
sudo gedit /etc/wvdial.conf
Code:
[Dialer 3g]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
New PPPD = yes
Modem = /dev/ttyUSB2
Baud = 921600
DialCommand = ATDT
Check Def Route = on
FlowControl = Hardware(CRTSCTS)
Username = vivo
Password = vivo
Phone = *99#
Stupid mode = 1
Auto Reconnect = on
Auto DNS = on
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2
Init3 = AT+CGDCONT=1,"IP","zap.vivo.com.br"
Then, set pppd with the appropriate permissions:
Code:
chmod +s /usr/sbin/pppd
Now, it is advisable to restart the computer and log back in. Then, plug the modem and wait for a few seconds. Its led will firstly turn red, then either green (3G network) or blue (2.5G network), indicating the modem has found the network and it is ready for dialing:
The green/blue led will blink on/off, indicating that the connection is established.
Note: to avoid execution errors when running wvdial, it is advisable to check the following:
- Make sure your user is part of the group “dip”.
- Set up appropriate permissions for pppd, as above.
