How do I delete my current number from showing up on my old iPhone 5?

[dirtybirds808]

So my girlfriend and I both upgraded our iPhone 5 to the our new iPhone 6.  We backed up both phones and transferred everything to the new phones.  I was thinking about selling the phones but I noticed that my current number is still on my old phone and my girlfriends number is still on her old phone.  The number is located when

I tried researching this but nothing seems to work.  I did the Settings/General/Reset/Erase all settings and content.  I have tried doing it through iTunes.  Its like the phone is ready to be set up as new, and everything is cleared on the phone except our numbers.  We are not signed into iCloud.  I even signed on to my iCloud account on my girlfriends old phone but her number still shows.  Its very frustrating. 

Bottom line, is I am trying to get rid of our current phone numbers that are still on our old iPhones.  Everything works perfectly on our new iPhone 6.

EDIT: I just realized that our old iPhones still says Verizon on them.  Do we possibly have to deactivate the phones some how?  If so, how do we do that?

Have you tried taking the sim out and then doing the factory restore?

Whoever buys your phone, by the way, will need their own sim card to use it. The sim contains the phone number information, so if nothing else, I would say to have whoever buys it bring a working sim with them, or have them call in and activate your old sim under their phone number. This shouldn't be a hard sell, after all, since most people will want to make sure the thing works before handing over money for it.

dirtybirds808,

Congrats on the new iPhones. Let's get all your information removed from your old phone. You have gone about the correct process so far with removing your information by going to Settings>General>Reset>Erase all content and Settings. After you select erase all content and settings do the device show the activation screen when you power the phone back on? If so do you go through the activation screen process again? If so, by going through the activation process again it will automatically associate your numbers with the device as it was previously activated on your lines. When you go through the reset process it removes the number but you will not be able to go through the activation screens again as it will then show your number.

Yes I was going through the activation process on both phones.  Weird thing is I did the same thing for my daughters old iPhone 4 (which I was going to use as an iPod) and her number cannot be seen.  Her phone doesn't show "Verizon" on it either.

I thought about keeping my girlfriends old iPhone 5 as a gym iPod  and when I go through the start up process, and using my apple ID, iCloud info, it still shows HER number.

So I have couple more questions:

If I decided to keep my girlfriends old iPhone 5, should i transfer in my sim card from my old iPhone 5?

I might give my old iPhone 5 to my brother.  Should I give it to him without a sim card and let him get his own?

Why does both phone 5's say Verizon, and my daughters iPhone 4 doesn't?

[nicholasbranson]

yes, yes, and because iphone 4 doesn't take a sim
