See this support document for information about the beta program. About iOS beta software - Apple Support  You cannot discuss issues with the beta software here on the public forum. Beta software is not to be used on your daily use devices, since they can contain bugs. If you need assistance, you need to contact Apple Support direct.

You probably need to remove the profile for the beta program. I would remove the SIM, wipe it with a clean, dry cloth and insert it again. Try restoring the phone, or try putting the device into DFU mode. Otherwise, you may have made a problem for yourself by trying public beta and not understanding the consequences. You can check for help on the signup page for the public beta.

If you continue this conversation, you run the risk of it being deleted by the hosts because of the beta NDA.

Google it.
