Hi
As R3 only supports usb on mpcie connector i search for an mpcie lte card which uses only usb and support german/europe lte frequencies.
My favorite provider uses these bands:
- LTE Band 3 (1,8 GHz)
- LTE Band 1 (2,1 GHz)
- LTE Band 7 (2,6 GHz)
- LTE Band 8 (900 MHz)
- LTE Band 20 (800 MHz)
Maybe change mpcie socket to ngff key e as only 3g/4g cards are supported by usb-limitation or bring 1 pcie lane from m2 sata slot to mpcie if possible to support pcie based cards too?
