iPhone 14 Mobile Data Not Working - Network Issues

I updated to the most up-to-date OS and it hasn't helped

same thing happened to me... I also used a physical sim... I called my network provider then they informed me that its a issue from their end and they talking for a solution with apple, until they fix it they said that they will give 100GB from higher bandwith kinda thing then instructed me to restart the phone after the call... After restarting the phone the issue didn't occour to me.

UPDATE (PROBLEM FIXED)

I went to my carrier store and got a new duplicate sim for my existing number, now i am not facing any issues. before that i had a visit to apple service center. As they checked, other sim was working fine so i got to know issue is with carrier. Maybe because of 5g sims coming recently and something with bands used in phone and i was using old sim that might have some old bands that could have removed from new phone. not sure but problem fixed

Similar experience on my iPhone 14 Pro Max, with iOS 16.4.1...

When using iPhone 14 Pro Max (without WI-FI service, e.g. highway, supermarket, any where without WI-FI), my device (iPhone 14 Pro Max) ran into connection problems: 

1. Safari "Fails" to respond to "search", or "Fails" to load the page from know URL.

   Its status shows the device is with signal (level at 4 bar) from LTE cellular network, 

   It shows status "Safari couldn't open the page because the server stopped responding".  

2. Apple Map "Fails" to "load the route" and Could not provide navigation (Device shows Map with "Loading Icon") 

   Its status shows the device is with signal (level at 2 bar) from LTE cellular network, 

   It shows status “A” route can’t be shown because of a problem connecting to the server”.  

Action-1: I tried to perform "Airplane mode" ON then OFF, which is to "warm boot" the cellular chip/system.

  Result 1-1 : "Airplane mode" ON then OFF, did not clear the problem.

  Result 1-2: The device's status shows the device is worst with signal (level at 0 bar) from LTE cellular network.

  Result 1-3: The device later shows a dialog box "Could not activate cellular data network"

  Result 1-4: The device is useless in this condition - it could not get Cellular system working"  

Action-2: I tried to perform power-cycle (slide to power off after pressing two buttons)

  Result 2-1: "cool boot" whole iPhone 14 Pro Max; and then Re-Start the device see "Apple logo" 

  Result 2-2: This FIX the problem and Restore Cellular connection and I can use the device as expected.

Later, My iPhone 14 Pro Max would ran into the Cellular connection and the problem repeated when using the device (without WI-FI service.) 

A: I noticed this problem with iOS (16.2) and files an problem report on Apple site on Jan 2, 2023; 

B: The same problem repeatedly happens even after many upgrade to latest iOS (even with 16.4.1). 

C: I brought my device to Apple Store for check up, and I was told there is no HW or RF issue, 

D: Store's engineer recommended to do "Erase-Install" the latest IOS 16.4.1 and with iCloud restore.

E. The same problem repeatedly happens even after this Apple Store visit with case number.

Note: I have another iPhone 11 Pro Max, and it does not have this problem. 

Currently, Getting Apple Support to help on this ....

Thanks for your info . Weird then how my problem only started happening after I got the vpn installed. I had my 14pro since dec with no issues till then. Hmmm … everything you said is exactly the same for me. Here’s what else I’ve observed : when I connect my phone to my car and car play kicks in, connectivity doesn’t drop but if I go from wifi to somewhere where data has to kick in automatically 9/10 times I lose connectivity . Maybe the 1/10 time I don’t lose it is when I don’t touch my phone for more than 5-10 mins after leaving wifi? I’ll have to test that out . Until recently I have had to resolve the issue by restarting my phone —which is a real b*tch—but now I put it on and off airplane mode . That resolves it too .

Has anyone who has apple care fought for a new phone ? Just wondering since this prob doesn’t affect all 14s.

I’ve been having the same problem as most people here. I believe the problem is the network & only affects individual phones. Maybe a glitch with the phone in combination with the network.

i recently traveled outside of the us to Central America & had no issues there, I actually experienced faster speeds & better signal. As soon as I flew back, the problem came back. I’ve tried everything from vpn disable network reset with no success. I’ll call T-Mobile one more time.

I have been experiencing similar problems with my iPhone 14. I have tried changing carriers and talked to a multitude of IT. I agree Apple products are more expensive than ever but worse quality ever. It seems that the Apple children spend too much time on development of new emojis and not enough on security and functionality. It may be time for something different.

I’m having the same issue. My maps also just randomly stops and teleports me to a different area. I’m on iOS 16.1.3 and Apple will not give me a new phone despite me going to the Apple Store 2 times so far each time a different location

Seriously lol and it appears there is no fix for this. How are these phones $1000s of dollars and can’t get the basic INTERNET TO WORK. Be better Apple, such an embarrassment.

I am having the same issue. Has this been resolved. My WIFI and my Cellular both become inactive and do not reactivate until I restart my phone.

I am having the same issue with my 14 plus. My wife has a Samsung and never has these issues. Been an Apple customer since the 1st gen iPhone. Time to trash the Apple and go to better technology.

I’ve found that some connectivity issues arise in my Iphone 14 pro max due to the 5G network. In areas where the 5G tower is farther away and the 4G tower is closer, the phone tries to connect to the distant 5G tower. As a result, even though it shows a 5G signal, the data flow can drop to zero because of the distance.

However, when the phone is closer to a 5G tower, the internet works properly. To fix this issue, I suggest changing the cellular settings from 5G Auto to LTE because it connects to almost all towers. LTE is also very fast and has resolved my connectivity problems. I hope this solution works for you too.

This is also why many people are saying their old iPhones are better than the newer ones, as the older models don’t have 5G and thus don’t encounter this problem.

Yup apparently this s**t has been going on for years, it's happening to me now to, this will be the reason I switch to android

I had the same problem, as noted, IPhone 14 does not use SIM card, at least mine doesn’t, it uses an eSIM. There were two eSIM #’s assigned to phone, under Sertings/Cellular. It appeared the old SIM card # number was assigned too. The primary was set and turned on for the wrong one, not eSIM.

IPhone 14 allows for two eSIM #’s, primary and maybe business. Once I deleted the secondary and used the latest eSIM, everything seemed to have started working properly. I now can get data over cellular.

keep fingers crossed it continues to work. Maybe Apple has a problem using 2 eSIM’s.

Good Luck

for the past 3 months I have the same issues with a 14 pro max is terrible I did everything close open the phone switched the SIM card and check it on another phone if there are network problems everything was fine when the sim was in the other phone.

even the data transfer between my Garmin Tactics 7 Pro Ballistic didn’t work and is lagging sometimes there is no data transfer between the watch and the 14 pro Max extremely disappointed

were other people with 13 pro max and 14 rpm and other types of phones they have signal and everything else working properly my 14 pro max is not working even basic phone calls I can’t make this is outrageous.
