Connect to 3G (yet again)

Question

I'm trying to connect to a 3G network via a Huawei E173 modem. Thankfully it is getting recognized as a usb modem without me having to deal with modeswitch

Bus 001 Device 006: ID 12d1:1436 Huawei Technologies Co., Ltd. Broadband stick

Next I installed wvdial and set up the config file

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
; Init3 = AT+CGDCONT=1,"IP","telenorbg"
Modem Type = Analog Modem
ISDN = 0
New PPPD = yes
Username = { }
Password = { }
Modem = /dev/gsmmodem
; Modem = /dev/ttyUSB0
Dial Command = ATD
Stupid Mode = 1
Phone = 0896182325

; Baud = 115200
; Baud = 3600000
Baud = 9600

I've tried any combination of all the settings you see commented and nothing has worked. When I run sudo wvdial this is (almost) always the output

--> WvDial: Internet dialer version 1.61
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

--> Sending: ATD0896182325

^CCaught signal 2:  Attempting to exit gracefully...
--> Disconnecting at Tue Oct 16 19:55:51 2018

Is there anything I can do or this stick is just not going to work? I tried it on a windows machine and I had to install a bunch of drivers before it would work.

Managed to resolve the issue by changing Phone to *99#. Final config:

[Dialer Defaults]

Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","telenorbg"
Stupid Mode = 1
Modem Type = USB Modem
ISDN = 0
Phone = *99#
; Phone = 0896182322
Modem = /dev/gsmmodem
Username = *
Password = *
New PPPD = yes
; Auto DNS = 1
Baud = 115200
