Q: my imeesage is linked to my email instead of my phone number on my iphone 5s, how do i fix it?

Hello smal3370,

If you are not seeing your phone number in iMessages settings, sign out of iMessage on your iPhone and sign back in so your iPhone sees your phone number to link it all up. For more information, take a look at the article below.
