The returned error is pretty generic:
>>>>>>   status error = 'Failure' (0x00000002)
>>>>>>   service      = 'basic-connect' (a289cc33-bcbb-8b4f-b6b0-133ec2aae6df)
>>>>>>   cid          = 'connect' (0x0000000c)

I checked the mobile-broadband-provider-info database and see that
this "www.plusgsm.pl" APN should also use authentication with username
"plusgsm" and password "plusgsm". Could you try that?

$ mmcli -m 0 --simple-connect="apn=www.plusgsm.pl,user=plusgsm,password=plusgsm"
