iPhone 14 Pro Cellular Connection Issues

VPN frequently creates more problems than it solves. But one important fact is that when you install VPN it configures itself to the specific hardware, iOS version and network that the phone uses. If any of those change it can break the VPN. So any time you change any of these you need to delete the VPN app and profile, restart your phone then add them back (if you still want to use VPN) so it can configure itself to the new environment.

Something to think about→Don't use VPN - GITHUB

There are two legitimate purposes for using VPN:

• To allow access to a private network such as a school or business when you are not on site. 
• To allow access outside of a country with a repressive government that has restricted Internet access. (This has suddenly become more important)

Any other use is risky, and can lead to problems like the one discussed in this thread. VPN disguises your location by making you appear to be somewhere else in the world. But you usually can’t control that “somewhere else”, and if it is in a location that an app isn’t approved for the app won’t work. Plus the fact that the provider of the VPN knows everything about you and your location, as well as what sites you access through the VPN. So you are totally dependent on the VPN provider’s honesty. As a start, if the VPN is free, DON’T USE IT. The provider has to make money somehow, and if you aren’t paying them then they are selling your private data to make money. But even those that charge can’t necessarily be trusted. For example, a few years ago Avast was caught selling user browsing data. They claim they have stopped doing so. 

You don’t really need VPN when using public Wi-Fi, because all communications between your device and the servers it accesses are end-to-end encrypted.

If you want VPN for privacy about the sites you visit, that’s not a good choice as discussed; instead you should download and use the TOR browser.

With iOS 15.2 and later for iOS/iPadOS and MacOS Monterey 12.2 and later Apple now has iCloud+ Private Relay, which is not VPN, but provides a safer browsing environment than VPN, and it doesn't spy on you→About iCloud Private Relay - Apple Support

Yes. Frequently. In my case, I recently switched from Samsung S22 Ultra to the iPhone 14 Pro Max. My cellular provider is US Mobile. My plan communicates over Verizon networks. Never had a single problem in two years with my S22 or cell provider.

Example, if I'm driving for an hour so and using CarPlay, I noticed that when my connection changes from 5G to LTE a data connection loss occurs. Streaming Music from various streaming services, phone calls, text messages and navigation simply stops even though the iPhone's radio shows that data is connected with 5 bars. Siri responds with a type of connectivity issue response.

When the data connection changes from LTE back to 5G, data connection still fails. I've tried enabling and disabling airplane mode, enabling and disabling cell connection. I disconnect from CarPlay and try music, texts and calls but it still fails. Nothing helps other than rebooting the phone.

I've already tried resetting network settings, etc and all of the other canned responses from apple support and other sites. Its upsetting, 1200.00 for an unlocked iPhone. Plus cases and MagSafe chargers , cable extensions for home and vehicle. Almost 1500.00 worth of apple products in total.

My iPhone is running 16.2. I've read that this might be specific to Verizon but who knows. Personally, it feels like a firmware issue. Hopefully something that can be fixed in software. I only have one week to return everything so I hope a fix happens fast.

I have an iphone14 and m facing the same issues. my network is pretty strong on 5G and my other android phone has no issues with same network provider, but the 14 keeps losing data connection pretty much every now and then. its surely not the cellular service company. Have enabled 5G and the "Allow more data on 5G" option. Changed the date and time setting to "automatically"; this I got from some other groups. restarted the iphone14 multiple times...but all to no avail!!! frustrated with my new purchase.

I know this is an older thread but this is currently an issue on iOS 17.1 when the iPhone switches from between LTE 5G and 5Guw..you will lose data connection. It is not a 14Pro issue it has followed me since the 12 Pro..I thought it was the 12 Pro not having a decent 5G compatibility but I see this is a real issue with all Apple phones regardless of the model or iOS. This happens regardless of the service area good or poor...

I would reach out to Verizon. I have AT&T and have no such issues on either our iPhone 14 Pro or 14 Pro Max.

T Mobile told me I cannot use VPN, and then the cellular will work. crazy.

when i went into T-Mobile and notified them of this issue. it took several days but i found that i was no longer having the same outage and dropped call issues. hopefully it will stay this way

Take the phone to an Apple store for analysis. Make an appointment first, or use the Get Support link at the top of this page to set one up.

Suggest that you disconnect VPN.

Why did you respond to me? Did I say I use VPN?

I'm with T-Mobile and having similar issues. No problems on WiFi but frequent connectivity issues with cellular data. Very frustrating when I can't use GPS even though i have 3 or 4 bars on 5G. Rebooting sometimes works but often requires 3 or 4 or even more reboots. Right now 11/1/2022 I loading a new software update with hopes that will be the solution. When the 5G works it's faster than my WiFi but more often than not I just can't access any cellular data.

I just got the iPhone 14 Pro Max and I used to have the iPhone 11 Pro Max. Ever since I switched phones, i’m having issues with my cellular data. My data is turned on but it would stop working randomly several times throughout the day and would not work until I restart my phone. I would restart my phone at least 10 times a day to make my data work again. Could you imagine having to restart your phone that many times a day?! This is super annoying…as this is a new phone. I even got a new esim but that did not solve the issue. I’ve never had these issues on my iPhone 11 pro max. Not sure if this is an IOS issue or manufacture issue. Please assist.

If you use VPN delete the VPN app and profile.

I also have iPhone 14 pro max connectivity issues.

It seems like iPhone 14 Pro Max hardware issues since there are so many people having the connectivity issues.

I have to reset/ re-connect to the network by turning the Airplane mode off then back on several times a day, everyday. Very frustrated.

I ran into similar problem and only power off my iPhone 14 Pro Max will fix problem temporarily.

I followed with your approach and called my Carrier, Verizon, and went through checking on EMSIM info and power off my device and Verizon tech tried to re-initiate data setting part. Hopefully, this will fix my problem.
