How to resolve 'Not Trusted' pop-up message on iPhone?
Hi. Repeatedly getting this pop up message. What’s going to happen after 5/5/26
[Re-Titled by Moderator]
Original Title: Not Trusted pop up
iPhone 14, iOS 26
More Details might have some info about the problem.
That might be a calendar, so look for a subscribed calendar you don’t recognize or don’t need, and remove it. See if that resolves the pop-ups:

But it’s also distinctly possible you’re using a web browser or app or such, and the certificate being presented by whichever EE (BT?) server you’re accessing is misconfigured or incorrect.
IIRC, the following BT Wi-Fi is (was?) associated with EE, and the same issue.

If it’s not a calendar, and you’re using EE (BT?), contact EE (BT?) and ask them about it.
