Yes you can. Your dad just needs to go to Verizon and tell them he wants to port a number. All he would need to do is pay the price of the iphone with a 2 year contract with i think is still $199 with verizon. He will need your mothers info, and actually she will need to be there too. She needs to give them her billing account number and some other info, your dad cant just give it to them because it is in your moms name.
