iPhone 15 and iPhone 14 lost data connectivity after iOS 27 update

Merely because you and your husband have both completely lost cellular data connectivity after updating to iOS 27 or higher does not necessarily mean that the issue is related to iOS or the iPhone itself.

You are using an iPhone 15, while your husband is using an iPhone 14. Since the same issue is occurring on two different iPhone models, it is important to consider other possible causes rather than immediately attributing it to the iOS update.

The issue could be related to your cellular carrier, a network outage or service disruption in your area, the SIM cards, carrier settings, or a problem with the local cellular network. It could also be a carrier-specific compatibility or provisioning issue.

If both devices are using the same carrier and are experiencing the same loss of connectivity in the same geographical area, that would make a carrier or network-related issue a particularly strong possibility.

Therefore, the fact that both devices are running iOS 27 or higher is not, by itself, sufficient evidence to conclude that iOS 27 is responsible. The underlying cause needs to be investigated before attributing the problem to the operating system.

Not every issue an individual encounters on their device can be attributed to an iOS update. iOS 27 or later may have coincided with what you are experiencing, but that does not mean the issue was triggered by iOS. Coincidence in timing is not, by itself, evidence of causation.

If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook.

The absence of such widespread reports strongly indicates that the issue is not a general, system-wide problem with iOS 27 or later, but rather something specific to the individual device, its configuration, installed apps, settings, hardware, or another interacting factor.

In short: iOS 27 or later may be a coincidence in timing, but there is no basis to conclude that iOS itself triggered the problem simply because the issue appeared after the update.

See what each update does: About iOS 27 Updates, About iOS 26 Updates, About iOS 18 Updates, About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...

You’re not entirely wrong but this happened on both of our devices, both after installing iOS 27, and there are a fair few Reddit users posting about similar issues. I wouldn’t call it widespread but I would call it coincidental either. Besides, did you read the rest of the post? Part of the reason I’m posting here at all is to see if other people are having this problem.
