My contacts are locked!
I have VZW Backup Assistant and using it online is the only way I can modify my contacts. I thought maybe it was the source of the lock, but a *RESET# did not resolve it. My outgoing calls have never been blocked.
Settings/Phone Settings/Security/Restrictions/Incoming Calls/Contacts Only
Since you can't easily toggle the choice with /Allow All/, I believe the cure is worse than the disease. It's also further evidence that this is a poorly designed phone. Inconsistently, /Contacts Only/ is missing from text messages.
