iPhone 17 pro Cellular Connection Issue

I am incredibly frustrated and hoping someone from the community or an Apple representative can help me resolve this. I bought a new iPhone 17 Pro on launch weekend and it has a significant, persistent issue.

Here’s a breakdown of what has happened so far:

  • The Issue: The phone's cellular connection repeatedly fails. It goes from 5G to "no service," then to "SOS." This also causes repeated dropped calls. For context, the call dropped roughly 9 times during a senior support call. Apple Support: I've been in contact with Apple Support since day one. Their stance is that it's a carrier issue. I have a case number: 10**********. The senior advisor on the phone confirmed the issue was clearly documented.
  • Verizon Support: I have worked with Verizon's support team, and they have confirmed that they have done everything possible on their end. They believe it is a device hardware or software issue.
  • The Replacement Catch-22: Apple has told me they will not send a replacement device without charging me for a new one. They also stated that if they can't replicate the issue, I will be charged, and my original phone won't be returned. This is an unacceptable policy.
  • Left Without a Phone: To make matters worse, I've already sent my previous iPhone 12 Pro Max in for a trade-in credit, leaving me without a functioning device.

I am completely stuck. It's a brand new phone with a major issue, and neither Apple nor Verizon is taking ownership. I'm hoping someone here has experienced a similar situation or can offer some advice. Is there a way to escalate this with Apple to get a replacement without this unfair policy?

I’m glad to hear the issue was resolved by your actions. Apple does not recommend the use of VPN’s unless required by employer or school. If the users installs the software, they’re responsible for the use of it intended or otherwise. By the very nature of the way a VPN works, protective settings are changed. The VPN now controls certain aspects of your device.


Apple provides a means for you to reset those settings by when the VPN and associated software removed.

That overstates Apple’s position. Apple does not say people should avoid VPNs unless required by work or school. In fact, Apple publishes documentation for setting up and managing VPN connections and it provides deployment support for VPNs including multiple VPN types and third-party VPN clients. That is support and accommodation, not a general recommendation against VPN use.

Find documentation from Apple that says every user needs a VPN. Offering support and accommodation for VPN installation and use is not a recommendation. Apple supports the businesses and institutions that require the installation and use. But a recommendation, no.


When I worked for Apple I was required to use a VPN because of the confidentiality of the material. They have their place. But in my experience the average user uses it because they want sidestep Netflix and other regional based restrictions. They also don’t understand the risks they expose themselves to. Can you please explain the business model of offering free VPN services?

You’re rebutting a claim I didn’t make. I never said Apple says every user needs a VPN. I said Apple does not tell users to avoid VPNs unless required by work or school.


Those are not equivalent statements.


Apple supporting VPN configuration and publishing documentation about VPN use shows it treats VPNs as a legitimate, supported function of the platform. That is enough to reject the claim that Apple’s position is essentially “don’t use a VPN unless your employer or school requires it.”


Your anecdote about working at Apple and your views about why average users use VPNs are not evidence of Apple’s official public position. And bringing up free VPN business models is a red herring, that is a separate issue.

That is incorrect.


Consider the many iPhone Accessibility features. These features are well publicized and documented by Apple, and clearly useful for the audience that needs them. Accessibility is a legitimate, supported function of the platform. Does that imply that there is no reason for most users to avoid using the Accessibility features? Absolutely not.
