Wow...I just learned something new. I am deciding if I want to use my cell number as my business line. I figured when I was home I can just route the calls to my home line so I didn't use my airtime. But with Verizon, you are still charged airtime when you forward your calls to a landline!

So what's the advantage to that? That would defeat the purpose for why I would do that.
This is probably not news to many of you, lol. But it was just a definite eye-opener for me.
From their website:
Description
Forward your calls to another phone number, including your home or office number. Your wireless phone will not ring until you deactivate the service. Airtime applies to forwarded/transferred calls even if you send the call to wireline telephones. When forwarding calls to phone numbers outside your local calling area, you’ll be billed for any toll, long distance, and airtime charges incurred. Additional per-minute charges may apply to all forwarded calls. This feature is also known as "Immediate Call Forwarding".
