Hello @bcadou you would be better querying this with Apple since it is turn who push the updates to your phone not EE. Carrier settings include things such as internet APN, message centre number and settings for making the phone and its features run in general such as voicemail, call forwarding etc. 🙂

Don't forget that it probably contains some update that will render your phone completely useless so it will mysteriously stop working 2 days after your warranty expired forcing you to upgrade to a newer handset!
