I want to connect to the internet using D-Link DWM-157 3G USB Modem, with Raspberry Pi 3 and Raspbian Jessie as OS (latest version).
I've tried billions of methods without success!!

This is so far where I have gone:

Fortunately, the modem has been switched to modem mode, and lsusb confirms that. Also, it has registered 4 ttyUSB devices, ttyUSB0~3.
Now, the internet icon at the top-right corner of the desktop with two top-down arrows, is blinking, which probably means it's trying to connect (but no success!)

I've tried to connect with wvdial and also sakis3g.

The following is /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 = { }

and also the following is /etc/sakis3g.conf :

APN="mcinet"

Here are the output:

sudo wvdial

....

....

Modem initialized.

Sending ATDT*99#

Waiting for carrier.

ATDT*99#

ERROR

OK

Invalid dial command.

Disconnecting at .....

and also:

sudo ./sakis3g --interactive

......

Preparing Modem ...

Registering Network ...

Modem unable to register a network.

So, what should I do!?
Any help is highly appreciated.

Edit1: I've tried this modem on Win7, and it works without problem.

Edit2: The following is the debug log of sakis3g:

pi@raspberrypi:/usr/bin/modem3g $ sudo ./sakis3g connect --pppd --debug
