I have a family account. I have had it for several years. I pay a fee for shared data, plus $40 per smart phone (x 3 phones) and $30 per dumb phone (x1).
I recently upgraded one of the smart phones (a Verizon-purchased iPhone 5) with a Verizon iPhone 6.
Verizon charged me $40 to "add" the phone. I didn't "add" a phone, I replaced a phone. I'm, additionally, paying additional Assurian insurance on the new iPhone 6 (was $9 for the iPhone 5, now $11 for the iPhone 6).
How can you justify charging me $40 to "add" a phone?
