iPhone 17 Pro Max – Connectivity Issues

Hello from France,


I purchased an iPhone 17 Pro Max (1 TB) on Friday, September 19, and I’d like to report two persistent issues.


1. Cellular and Wi-Fi disconnections

The device has lost its cellular connection twice so far.


  • On Sunday morning, I unexpectedly had to re-enter my four-digit code to enable the 5G connection.
  • On Tuesday evening, I realized it had disconnected again—this time from both 5G and Wi-Fi.


I found online discussions suggesting that VPN apps may cause this issue. I uninstalled my “VPN – Super Unlimited Proxy” app, and I’ll see if that helps. Still, I hope a future update will address this problem.


2. Bluetooth connectivity

This issue seems to be more common:


  • My iPhone pairs with my AirPods without problems.
  • However, it does not connect to my car system or to my Jabra earbuds.
  • I even reinstalled the Jabra app, but the iPhone still doesn’t detect my earbuds—while, amusingly, it did detect my father’s old mobile phone.


I don’t expect a team to jump directly onto my device, but I do hope this message helps bring attention to these bugs and contributes to a fix in future updates.


Thank you, and take care.

iPhone 17 Pro Max, iOS 26
