Missing bands EM7455

IoT Modules MC/EM Series
1

I use a EM7455 in German LTE Telekom network and I miss the bands B32 and B32.

The module works in a Lenovo machine.

Firmware
Manufacturer: Sierra Wireless, Incorporated
Model: EM7455
Revision: SWI9X30C_02.33.03.00 r8209 CARMD-EV-FRMWR2 2019/08/28 20:59:30

Thank you.

I don’t see B32 is supported in this module:

And I think, its the the same with B28, right?

What about permitted LTECA - which may be the reason for this, firmware, provider or hardware (PC)-manufacturer?

All possible combinations in German Telekom LTE network are permitted.

F.I.: B3: B7, B20

B28 is not supported in EM7455

How B28 has to be enabled?

At the moment I see this as capable bands:
