I would like to purchase a Moto G4 4th Gen from Republic as a replacement to my daughters Moto G4 2nd Gen. How di I order it as a replacement and keep the same phone #?
Assuming you have a moto G1 or G3, you simply order the phone and receive it. During the activation process you will be given the option of replacing/upgrading which will transfer the phone number from the old phone to the new phone.
Note all new phones are on plan 3.0. So make sure the plan change works for you.
