Question

[MasterCopipaster]

Зарание извиняюсь если не там задаю вопрос, но вроде как более подходящей категории не нашел

Имею на борту Ubuntu 20 и USB модем ZTE WCDMA Technologies MSM MF110/MF627/MF636
Оператор Airtel - интернет на телефоне работает отлично. Задача настроить через USB модем.
Почитал вот эту статью, и посомтрел еще конфиги вот тут - не заработало. Что наверное ожидаемо - веть статьям почти 10 лет.

$sudo nano /etc/ppp/options

$sudo wvdialconf /etc/wvdial.conf

Ну и собственно на этом все.
Конфиг модема:

/etc/wvdial.conf

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","airtelgprs.com"
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyUSB1
ISDN = 0
Phone = *99***1#
Password = airtel
Username = airtel
Stupid Mode = 1

Собственно я в этом не разбираюсь совсем, и прошу помощи у знающих людей. Что с этим делать?
