Correct Settings for Telekom LTE Speedstick

Hey guys, I got my GLINet Shadow up and running. The only missing thing is to get the LTE Settings done for my USB 4G modem (rebranded HUAWEI E3372).

I tested a lot but it seems not to connect anytime. XXXX for my pin of the sim card, is there missing an entry for TTL?

Is the pincode, dial number, usename and password needed? Pls make sure these are necessary.

Try change the device.
