Description of problem:
When I try to connect to a mobile broadband. it doesn't connect instead gives this error.
SELinux is preventing pppd from 'write' accesses on the file ppp0.pid.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that pppd should be allowed write access on the ppp0.pid file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pppd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
