Transfer att plan to Verizon phone
My sister gave me a iPhone 11 which is huge from my iPhone SE . She had Verizon and switched to att. She had to surrender all her Verizon phones except the one she gave me. It has been wiped clean and restored to new . I am currently on family plan with my son being account holder. How to I transfer my plan from iPhone SE to the iPhone 11?
