Wvdial.conf dial errors. Raspberry Pi Model B Huawei E1820 3G Modem

Linux is kicking my butt. I have attempted to use wvdial for the first time to get 3G working on my Raspberry Pi, but things have not gone as expected. First of all, when I do a simple sudo wvdialconf The scan gives me the following message: Ok. Probably not the best start I can get because of the errors on lines: ttyUSB0: ATQ0 V1 E1 S0=0 -- ERROR ttyUSB0: ATQ0 V1 E1 &C1 -- ERROR ttyUSB0: ATQ0 V1 E1 &D2 -- ERROR I figured that these errors could probably be the reason of the failure of my later attempt to use wvdial, which gives me the output as such: --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ0 V1 E1 +FCLASS=0 OK --> Sending: AT+CGDCONT=1, "IP", "internet" AT+CGDCONT=1, "IP", "internet" ERROR --> Bad init string. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ0 V1 E1 +FCLASS=0 OK --> Sending: AT+CGDCONT=1, "IP", "internet" AT+CGDCONT=1, "IP", "internet" ERROR --> Bad init string. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ0 V1 E1 +FCLASS=0 OK --> Sending: AT+CGDCONT=1, "IP", "internet" AT+CGDCONT=1, "IP", "internet" ERROR --> Bad init string. To provide some background on my configurations: My wvdial.conf looks like this: [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 +FCLASS=0 Modem Type = Analog Modem ISDN = 0 New PPPD = yes Phone = *99# Modem = /dev/ttyUSB0 Username = username Password = password Baud = 9600 [Dialer E1820] Init1 = ATZ Init2 = ATQ0 V1 E1 +FCLASS=0 Init3 = AT+CGDCONT=1, "IP", "internet" Stupid Mode = 1 Phone = *99# New PPPD = yes Modem = /dev/ttyUSB0 Username = username Carrier Check = no Password = password Baud = 9600 and my dmesg logs look as such: From these outputs, I infer (or possibly wrongly assumed) that my Huawei E1820 has indeed been turned into a modem and is ready for wvdial dialing. Additional Info: The SIM Card I'm using has been disabled of SIM_PIN and is bought from Chunghwa Telecom, a major telecom company located in Taiwan. ***Updated*** Hi all, I have tried changing my configs in the /etc/wvdial.conf file and now it looks as such: [Dialer E1820] Init1 = ATZ Init2 = ATQ0 V1 E1 +FCLASS=0 Stupid Mode = 1 Modem Type = Analog Modem ISDN = 0 Phone = *99# New PPPD = yes Modem = /dev/gsmmodem Baud = 460800 Username = username Carrier Check = no Password = password Now when I run wvdial, I get such error: --> WvDial: Internet dialer version 1.61 --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 +FCLASS=0 ATQ 0 V1 E1 +FCLASS=0 OK --> Modem initialized. --> Sending: ATD*99# --> Waiting for carrier. ATD*99# ERROR --> Invalid dial command. --> Disconnecting at Sat Aug 20 08:53:35 2016 I suspect that the reason for this is either: * the modem is not working as expected, or * the parameter Phone in the /etc/wvdial.conf file is not properly assigned. Hope I get this to work. Any ideas out there?
