Unfortunately, there appears to be an issue with your specific account.
We recommend calling Verizon Technical Support and stating the following:
1. "I am unable to activate conditional call forwarding on my number. Dialing the star nine zero (*90) activation code does not work. Can you activate my conditional call forwarding for me? I want it to forward calls when busy"
2. When they ask what number you would like your calls forwarded to give them this number: (551) 202-7253
- Please don't mention CallHero, your carrier might state that they do not support third-party applications as a way to avoid dealing with the request.
- If the representative is unable to help you, ask to speak to another representative or supervisor. Do not let them tell you that they can't activate conditional call forwarding. Call forwarding is a carrier side setting and only they can get it activated
