How to reset your iPhone

This guide explains how to reset your iPhone when you are no longer going to use it or it has an issue.

Warning - NHSmail MFA

If you use this device as your primary authentication method for NHSmail, either via the MS Authenticator App or the iPhones mobile number, you will need to make sure you have an alternative sign-in method setup on this page.

Please make sure to do this before following the rest of this guide.

Failure to do so will result in you being unable to login to NHSmail without assistance from the IT Service Desk.

Warning - Apple ID MFA

If you are no longer going to use the mobile number attached to this iPhone, and you have Two-factor authentication enabled on your Apple ID, you will need to replace the mobile number attached to your Apple ID.

To do this, you will need to login to your Apple ID, go to the Account Security section and add a different number you currently have access to, then remove the existing number.

Failure to do this may prevent you logging in to other devices with your Apple ID. It could also mean you have to contact Apple to perform an account recovery, which could take weeks.
