You can log into MyVerizon or call into customer service and do a device switch. Since both are Iphone 5's you could technically also just switch SIM cards but you'd probably want to factory reset the devices before transferring so you don't have eachothers contacts/media.
Well it all depends on what in stake if it's just an easy swap she doesn't mind what on your phone and you don't mind what's on her's just switch the phones give her a big hug & say love ya sis and go on. But if there is a little more to it and you want things specific to your taste on the phone she's giving you then i would do as crelin suggested in his post. Pull the Sim's safely set them aside and do the Full restore on the phones Now remember when you fully restore your iPhone's they'll revert back to when you pulled them out the box for first time and you'll will need to reload anything you didn't save as in apps and your phone book..
But other than that it's just Milk & Cookies... b33
Thank you all for taking the time to help out! I really appreciate it.
That's really nice of you switching your iPhone with the larger memory with your sister!
The switch is very simple. All you have to do is just sign in to your My Verizon account to make the switch. Visit http://vz.to/HaDHBO and sign in to your online account.
Once you switch the devices online make sure to swap SIM cards as well. Once the phones have been switch visit http://vz.to/163istr for steps on the activation.
keep me posted if you need further assistance.
