Husband and wife’s phones sharing everything

You didn’t properly sign out and erase the phone so he could set it up with his own information. You need to follow the steps at What to do before you sell, give away, or trade in your iPhone or iPad - Apple Support

So far, it sounds like your phone and your husbands phone are using same Apple ID.

All that you can do is try the following to see if helps with Messages.

On your phone......

Tap Settings

Scroll down and tap on Messages

Tap Send & Receive

Make sure that the only check mark is next to your phone number

On your husbands's phone.....

Tap Settings

Scroll down and tap on Messages

Tap Send & Receive

Make sure that the only check mark is next to your husband's phone number

No guarantees, but worth a try. For the future......Every user needs to have their own Apple ID.

Did you remove the device from your apple account? Sounds like the two devices are syncing through iCloud.

Go to settings on your new phone and click on your name at the top. Scroll down and see what devices you have listed. If it's there, click "remove".

Hi Catandbas,

I understand that you dislike the fact that your husband is getting all your messages. You can fix this problem in 3 steps.

1. Go to settings
2. Select General
3. Scroll to the bottom of the screen and select Transfer or Reset IPhone
4. Press Reset

Good Luck!

Hi again,

I don’t think it is possible to do what you desire.
