Conexão com o modem USB DWM-157 3G da D-Link

Question

Eu quero me conectar à Internet usando o D-Link DWM-157 3G USB Modem, com Raspberry Pi 3 e Raspbian Jessie como SO (versão mais recente). Eu tentei bilhões de métodos sem sucesso !!

Isto é tão longe para onde eu fui:

Felizmente, o modem foi alterado para modem mode e o lsusb confirma isso. Além disso, registrou 4 dispositivos ttyUSB, ttyUSB0 ~ 3. Agora, o ícone da internet no canto superior direito da área de trabalho, com duas setas de cima para baixo, está piscando, o que provavelmente significa que está tentando se conectar (mas sem sucesso!)

Eu tentei me conectar com wvdial e também sakis3g .

O seguinte é /etc/wvdial.conf :

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","mcinet"
Stupid Mode = 1
Modem Type = Analog Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Phone = *99#
Username = { }
Password = { }

e também o seguinte é /etc/sakis3g.conf :

APN="mcinet"

Aqui está a saída:

sudo wvdial

....
....
Modem initialized.
Sending ATDT*99#
Waiting for carrier.
ATDT*99#
ERROR
OK
Invalid dial command.
Disconnecting at .....

e também:

sudo ./sakis3g --interativo

......
Preparing Modem ...
Registering Network ...
Modem unable to register a network.

Então, o que devo fazer? Qualquer ajuda é muito apreciada.

Editar1 : eu tentei este modem no Win7 e funciona sem problemas.

Edit2 : O seguinte é o log de depuração do sakis3g:
