To get /dev/bandrich (so that you don't need to look for which /dev/ttyUSBx
is used by your dongle, and always use /dev/bandrich), add a udev file:
/etc/udev/rules.d/bandrich.rules
containing one line:
SUBSYSTEM=="tty", ENV{ID_VENDOR_ID}=="1a8d", ENV{ID_MODEL_ID}=="100d", ENV{ID_SERIAL_SHORT}=="357473040068155", ENV{ID_USB_INTERFACE_NUM}=="02", SYMLINK+="bandrich", MODE="0666"
Change vendor_id/model_id/serial/interface num to match yours.
Use lsusb -v to find values. For interface num, I'm not sure.
It corresponds to /dev/ttyUSBx (the x). I did:
cat /dev/ttyUSBx
in one terminal, and:
echo -e "AT\r" > /dev/ttyUSBx
in another one. And I took a number for which the first terminal displayed:
AT
OK
"02" (/dev/ttyUSB2) worked for me.
Here, I get, as result of lsusb -v:
[SNIP]
Bus 003 Device 009: ID 1a8d:100d BandRich, Inc. 4G LTE adapter
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 0 (Defined at Interface level)
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 64
idVendor 0x1a8d BandRich, Inc.
idProduct 0x100d 4G LTE adapter
bcdDevice 0.00
iManufacturer 10 BandRich, Inc.
iProduct 9 BandLuxe HSPA-LTE Adapter
iSerial 11 357473040068155
[SNIP]
You can also run:
udevadm monitor
and unplug/replug the dongle. It will print some information.
The command:
udevadm info --export-db
is also important to get the right identifier to put in ENV{}. (It also
gives the correct value.)
Here is extracted what I have for my dongle:

Note: you need to unplyg/replug your dongle for /dev/bandrich to appear.
Note: the mode 0666 is for everyone to access the dongle (no need for
root privileges). If you prefer you can set it to 0600 (only root)
or 0660 (root and group).
Then you need to configure pppd, to get correct 'route' information when
you run wvdial.
The file /etc/ppp/peers/wvdial should have the following content:
noauth
name wvdial
usepeerdns
defaultroute
replacedefaultroute
The file wvdial.bandrich.conf has been created by copying some information
found on the Internet. Its content may not be fully correct. Adapt to your
situation. It seems to work here.
