LPWA - Dial-up network connections with WvDial

USB Connect LPWA can perform dial-up network (DUN) connections supporting the Point-to-Point Protocol (PPP). Below we give an example of how you can connect to the Internet using app WvDial. WvDial is a Point-to-Point Protocol Dialer: it dials a modem and starts PPP in order to connect to the Internet.

Step 1: Install wvdial

sudo apt install wvdial

Step 2: Edit /etc/wvdial.conf for the follows

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2
Init3 = AT+CGDCONT=1,"IP","lpwa.vodafone.com"
Username = gdsp
Password = gdsp
Phone = *99***1#
New PPPD = yes

Dial Command = ATD
Modem = /dev/ttyUSB1
ISDN = 0
Baud = 115200
; Phone = <Target Phone Number>
; Password = <Your Password>
; Username = <Your Login Name>

Change APN lpwa.vodafone.com and modem port /dev/ttyUSB1 to your own

Step 3: Start connection via command

The module must be attached to the network before starting the WvDial.

sudo wvdial

Step 4: Wait for connection

To exit the connection, enter the command CTRL+C
