How can I update my phone

Hello ~ You can go through the steps below and upgrade your iPhone yourself:

Update your iPhone, iPad, or iPod touch - Apple Support

Also if you need to use iOS 13,14 or 15 you will need a newer iPhone…as your device can only be updated to iOS 12. Go to black line at the top of this page on click on iPhone to see newest devices available.

Or:

Apple Store Online

Assuming it hasn’t already been updated to iOS 12.5.5, see: Update your iPhone, iPad, or iPod touch - Apple Support (CA)

Up grade my iphone now please.
