I recently added my brother onto our family plan, moving his phone number from his previous carrier. We added the iPhone 17 pro max with an unlimited ultimate plan to the number. He recently got an email saying that the promotion for a $200 gift card when switching to Verizon and adding a new line on myPlan was Invalid and the reasoning was that the line associated was disconnected. I'm wondering if there was an error and if I could get any help.
