Q: I activated my old iphone 5 for my husband on tracfone and he is getting my texts, emails, notifications, etc.  Is there an easy way to stop that from happening?

I activated my old iphone 5 for my husband (who doesn't want a phone but will use it in his car on trips) on tracfone and he is receiving all my text messages, emails, notifications, etc.  I didn't restore the phone to factory settings and it is registered to my email address.  I'm not sure what I have to do  so it gets his texts and emails and not mine.  I turned off icloud sharing on his phone but that didn't help.  Any suggestions would really be appreciated.  Thanks!
