Hello over there, 
here are some tips you could try:
USB Modems have proven easier to install, at least based on my
experience, first open the 'System Log', and follow 'kern.log', you
could use 'dmesg' or directly check the log files, the idea is to check
for creation of devices once you connect the USB Modem, if you are lucky
the kernel has support for it and successfully creates the needed
device, for example reading the 'kern.log' after connecting an USB
Modem:
---
usb 3-3: new full-speed USB device number 25 using xhci_hcd
usb 3-3: New USB device found, idVendor=0572, idProduct=1340
usb 3-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 3-3: Product: USB Modem
usb 3-3: Manufacturer: Conexant
usb 3-3: SerialNumber: 12345678
cdc_acm 3-3:1.0: ttyACM0: USB ACM device
---

in this case the modem is on '/dev/ttyACM0' then you could try 
'sudo wvdialconf /etc/wvdial.conf' 

again in my case, the beginning of '/etc/wvdial.conf' after creation
with 'wvdialconf' reads:
---
$ cat /etc/wvdial.conf

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyACM0
---

if your USB Modem is supported then you don't need any additional
drivers, you could tweak the system an linking '/dev/modem/' to
'/dev/ttyACM0' for easier access or installing 'gnome-ppp' for easier
configuration of your connection.
The thing to check is the creation of the device for the modem in '/dev'
give it a try,
good luck!
