I Cannot Connect To A Wireless Network - Blackberry 8703e User Manual

I am not receiving notification for incoming calls or messages
Try performing the following actions:
• In the profile list, verify that the Off profile is turned off.
• In a notification profile exception, verify that the Custom Phone Tune field is not set to Mute.
I cannot set some fields when creating a Calls From notification profile exception
If you assign a custom ring tone to a contact in the address book, a Calls From profile exception appears in the profile list. Because these
exceptions are for calls only, you can only set the Custom Phone Tune field.
