I use a Huawei E3372 modem, I have a fixed IP in T-mobile. On the helpline, they only know what my IP address is, they can't see the rest, but through a paid help desk with horror. Will anyone help to fill in this data ?:
Unfortunately, it does not connect to the APN = date alone, despite setting this profile as the default almost immediately goes to the factory profile on APN = Internet with dynamic IP.
