Cellular Data Connectivity iOS 14.0.1

Having the exact same issue. Leaving a note in hopes this gets resolved. Same as you tried solutions on the web but nothings worked.

Found a solution: Did a full reset of all settings. Iphone is now connected to LTE.

I have the same issue. Exact same App work under WiFi but just hangs with LTE. I don't relish a full settings reset where I have to re-add my CC's to Wallet. Can anyone else confirm the issue and have any other fixes other than waiting for the next iOS update in October?

same issue with XR, I tried everything, still not WiFi and LTE very slow.

I read several posts about loss of cellular connectivity (and many other issues) after upgrading to IOS 14.0.1. I tried the suggested fixes (turn on Airplane Mode then turn it off; Reset Network Settings; Force Restart) but no success.

The solution that worked for me (sorry I didn't save the name of the person who reported it) was to delete my VPN app. Then I restarted my iPhone 8 Plus and cellular works exactly like it should.

Anyone found a fix yet?

Model: iPhone XS Max

Issues since 14.1, currently 14.2:
cellular data: not at all or very slow upload speeds (less than 1 mbs), not at all or sometime good/very download speeds (0 or 250 mbs).
calls without wifi calling toggle active can get disconnected during the call or the other person cannot hear me while I can hear that person very well.
Carrier signal is at max level (4 bars) and there are no apparent issues with wifi or bluetooth.

I did everything! Literally checked every possible root cause:

Potential cause 1, the carrier:

• tried physical sims/ e-sims

• same sims in samsung worked like a charm

• different carriers for each sim

• called all of them, no reported outages on their side

• problem still there

Potential root cause 2, the phone:

• Spent more than 5 hours with apple support on the line while we went through all the steps (up to complete restore) and sent the full 30 mins diagnostics

• conclusion: no hardware / software problem

• recommendation: go to an authorized apple service provider

• did that, but they also didn’t find the problem (unofficial/ personal note from them: ios-related)

• installed the 14.3 beta 1 and 2, same problem

Since not everyone with XS Max is having this issue, I would assume it was something I did that may have caused this; there are two things I have in mind: 1. iPhone had ios 14 beta installed on it since it went public around June. 2. Always had a mdm profile installed for running work-related apps (and yes, of course I removed it when doing the tests).

I really believe this to be an iOS related issue and I hope the engineering team is on top of it.

Same problem here. Did the same things as @KarenL but still have the problem. It didn’t solve anything and since I don’t want to reset all my settings can someone please help with other alternative solutions for this horrible problem. Thank you very much

I have the exact same problem. I’m using iPhone XS with iOS 14.2 and ever since this update I cannot turn the toggle on for no matter which app to use my internet data volume when I’m outside and have no WiFi connection from somewhere. I tried all of the recommendations here (except the “reset all of the iPhone settings” because I don’t want to do that. At least not yet) and nothing worked. Can someone please help solve this terrible problem because it basically renders the phone unusable. I hope Apple notices this problem and fixes it ASAP with the next update. Thank you very much 

Reset Network Settings solve my problem , ios 14.2 iphone 11 pro max .

A reset of my Network Settings solved my problem. iOS14.3 iPhone 7. thank-you

Model: iPhone 12 Pro

hi, I have the same pb here. Since the beginning, and the moment I got this new iPhone (last Christmas) I have this problem. I’ve waited for the new uptade to see if it’d fix it but it didn’t (iOS 14.4) ive tried everything, from the cellular reset to the whole “reset & erase your iPhone” thing. I need some tips pls lol.

Same problem here iPhone xr I didn’t have issues until 14.4 and now have no internet connection, just spent time with apple support went through all the steps they recommended including reset and erasing of my iPhone which i just did and still nothing I hope this gets fixed quickly I can’t live like I have an iPod I work and am away from WiFi a lot I can’t be without communication

I turned off VPN and it worked...

I am on 14.4.1 and now experiencing this. At least twice a day. Hopefully iOS 14.5 fixes this.

Same issue. Thought it was something I had done. I’ve tried all the suggestions listed here, but nothing has helped. Come on, Apple, please fix. This is very frustrating.

Wasn’t having any issues until I updated to 14.4.2 last night on a 12 pro. Now can only use phone on wifi. I’ve tried restarting, every cellular option, turning airplane mode on and off. I don’t want to go through the tedious reset because it seems that isn’t working for people either. Any updates coming sooner rather than later? Anything that has worked without fail??

I've been experiencing this issue for several weeks now (iPhone Xs). I'm not sure whether the 14.4.2 update has caused it but it's possible. I tied the suggested Network Settings Reset but it didn't help, unfortunately. I don't have a VPN configured, so this can't be the issue. I haven't tried the general reset but hope to avoid it, so any other ideas please?

I am getting similar issue after upgrading my Iphone 12 mini to iOS 14.5 came today. Cannot use internet service. Call and SMS is working fine.

Same problem here. iPhone 12 mini. Updated to 14.5.1 and lost cellular data but WiFi works fine. Oddly though, the Ookla speed test app shows cellular data working as expected, but no other apps can find the internet.

Also, tried all the resets. Including reset all settings -still no dice. I guess I’ll be backing up >erase all content/settings> restoring next. Ugh what a paaaaaain

I had the same issue with iphone 11pro iOS 14.6. No data unless on WiFi. Went to Settings / General / VPN / Norton Mobile Security and turned off Connect on Demand, and it all seems to be working again. Hope it lasts !!

I have the same issue but my phone is iPhone 12 Pro Max. At first I though it have the problem with my carrier then I put my sim on Android is working fine. Then, I realized it not thing wrong with my carrier. The problem I have is the combination between T-mobile sim and iPhone12 Pro max (ios14.6). The iOS 14.6 seems not to working with 5G or LTE. Then, I download the newest version of iOS (14.7 beta). Now it works (5g unreliably, LTE reliably). I hope my solution will help your guys.

Always try simple things first (Im sure apple support and Tmobile will make you do them and send you through the loops)

I download the new version on the Apple Beta Software Program.

I have an iPhone 12 and am running 14.7.1 and am having trouble connecting to data over cellular still. Any real answers
