I'm trying to connect Dongle K5150 with Emnify SIM to raspberry Pi3 with iot core 17763 version. I followed these steps: USB Mobile Broadband Modem on Windows 10 IoT? but at the end I had an error: Connect Failure: error 0x139f.
Can someone help me?
I found the solution, the problem was in my "profile.xml".
In detail in two nodes:
<HomeProviderName>em</HomeProviderName>
and
<AccessString>em</AccessString>
