the issue is as follows:
First post - hacked by installing modem manager within container
This did not work for 2.7.5. There is no known workaround at the moment. I know @shaunmulligan has done some work, and I dont know the result.
Yes, I have seen the links. However I am having hard time finding modems with sim card slot already built in into it and being available on EU market. Thought maybe someone would recommend any. Huawei or any other easily available.
Most of modems I find without sim card slot, and I dont like the idea of adding sim card adapter. Would rather have out of the box solution.
