Are you sure it is an analogue modem? Is this entry needed?

The driver should create a number of devices, ttyUSB0/ttyUSB1/ttyUSB2/... =
Try=20
them all in turn, only some may allow PPP connections.

Unless you are just trying to dial out over a PSTN number (which you are no=
t)=20
you should be able to increase the baud to a higher number; e.g. 115200

Did you get anything more detailed in your logs?
Do you have a pap-secrets file even if empty? If not:
touch /etc/ppp/pap-secrets; chmod 600 /etc/ppp/pap-secrets
If it still fails try adding something like this:
# Secrets for authentication using PAP
# client server secret IP addresses
"user" * ""
HOWEVER ...=20
I thought that the whole idea is to use this modem to connect on a 4G (LTE)=
=20
network ... yes?
In which case PPP is not the correct protocol. If this Huawei is using=20
Qualcomm chipset you should be using the qmi protocol and the cdc_ncm drive=
r=20
ought to do all the dialling using this device (from your dmesg):
[22765.769603] cdc_ncm 1-1.1:1.1 wwan0: register 'cdc_ncm' at
usb-0000:00:1a.0-1.1, Mobile Broadband Network Device, 0c:5b:8f:27:9a:64
Other driver/protocols that can achieve high speeds of 4G are cdc-ether, cd=
c-
acm, but your card ought to pick out the correct available protocol from th=
e=20
corresponding kernel module. PPP incurs an overhead (due to packet=20
encapsulation) and throughput speeds will be slower.
That's how I understand these devices to work, but unfortunately I can't=20
verify any of this because I do not have access to such a device or a 4G=20
network. :-(
I hope someone else who does can chime in.
