iOS 14 no signal, no cellular data

Hi ,
I have the same issue: since a week or 3-4, no 4G on my iphone.
I tried everything that has been suggested already:
Airplane Mode
Hard reset
Soft reset
Network Settings Reset
Wifi calling on/off
VoLTE on/off
3G on/off
Checking "Modem Firmware"

I even went to the store to switch sim cards.
The first time, I had this issue - it was with my 4 year old iphone 6s - then I then bought the 7 (because I thought the 6s was broken) ==> issue remains

I then tried to switch off the possibility for the phone to have 4G (settings/mobile data options/convers & data = 3G) - so it only "takes" 3G now, not a possibility for searching for 4G , and this is going much better.
At least I have a connection now.
When I put it on 4G ==> the iphone is showing 3G connection but in fact there is no connection at all...

Hope this helps...
Nico

iOS 14.1 update did not solve the problem for me.

seem like the problem was from the third party app, Lockdown. After updating the app to the latest version, my WiFi is working again. If you have Lockdown installed, go and update to the latest version. It mention on the updates the VPN was causing WiFi issues

I'm experiencing the very same. There are multiple iPhone 11s in my household using the latest IOS 14 update and they have the same problems. No reset or any of the well known methods solve it.

Got the same problem after updating to iOS 14.
iOS 14.0.1 did not fix the problem
iOS 14.1 did not fix the problem as well
Only restarting phone helps
Now i got iPod instead of iPhone XS,
Apple can't fix this for 1 month, how much time should we wait?
Is it such a serious problem???????
I swear it's the last iPhone I've bought

I have a new iPhone Xs Max and out of the box I had connectivity problems. Wifi works just fine but the problem is with my reception as I get ,,No service'' all the time and unable to make calls. I went to Apple store in Frankfurt and they couldn't determine what's wrong, they ran diagnostics and told me that the phone has strong reception and nothing wrong with it but on the other hand I had a chat with Apple USA and they also ran diagnostics and told me that this could be a hardware problem, so I see conflicting opinions by Apple which extremely frustrating. The only solution that seemed to work but still unreliable is to reinstall iOS using DFU mode which made my phone receive signal for a couple hours but then dropped signal, so this means that it not a hardware but a software issue. I am on iOS 14.0.1 and will not update until Apple finally finds a WORKING solution to this miserable piece of technology. It is mostly unstable when 4G is activated in the settings so I have to switch to 3G manually so that I can receive signal which means that I am never getting 4G on this phone. I would still be relatively happy if it worked only with 3G but the signal also drops and I get ,,No service'' and only a restart fixes it which is EXTREMELY annoying and even sometimes a restart doesn't fix it and I am stuck with phone which doesn't make calls, how sarcastic is that! This is the biggest prank ever pulled by Apple on me which left me frustrated with a very expensive USELESS phone so I guess I am never buying an iPhone again!

No solution apart from restarting the device from my end.

However an apple support rep did get me to recreate the issue and perform diagnostics, after reviewing the logs he mentioned that the engineering team 'confirmed' it was a hardware problem. After getting my device replaced the issue is still occurring.

Hopefully iOS 14.1 which was just released solves this issue.

Problem fixed !
im using IPhone 7 and just installed iOS 14.1.0 using iTunes . Took an hour and several tries ( WiFi upload not work )
now have cellular- let’s see how long .
lesson learnt- dont install new iOS until maybe a month after released .
At least Apple listened and acted .

i was wrong :( updated to iOS 14.1.0 - worked for 3 hours .
way to go Apple- keep up the great work you are doing - NOT

iOS 14.1 update didn't work for me either. Has anyone tried 14.2 beta 4 update because I heard there is a modem update in that and may fix different connectivity issues?

I tried the iOS 14.2 Beta 2 version and it did NOTHING, issue persists. I can not go out with my phone because I don't have reception at all, instead I go out with my old yet reliable Nexus 5X :(

iOS 14.1...didn't solve anything. My iPhone 7 is still there...dead and USELESS...after the 14.0.1 update and now 14.1...nothing is changed.
I've advised all my contacts TO DO NOT UPDATE to 14.1 if their phone is not under warranty. I'm doing the same on MACOS for Big Sur.
It's a real shame that NOONE in Apple is doing, or saying, something to help us to get our iPhone working as before...not better...but AS BEFORE iOS 14, able to call/receive and browse Internet like phone with Android, for only 50€.
For Apple support we don't exist, 14.0.1 is working "perfectly" and for them it's only an hardware problem....That's All. They repeat the same "mantra". If you wanna fix...buy another iphone (as I've done...to get my data back).
Why don't allow me to install 13.7 again??? Why??? At least allow to your technician to do that in Apple Center...
It's unbelievable what's happening with this update...absurd and this "silence" is adding also more frustration.
The worst experience ever with Apple.

Having the same exact problem with my son's iPhone 7. He upgraded to 14.01. Got the cellular error. I tried to upgrade to 14.1 - upgrade failed. I tried to restore from backup - phone went into cycle between Apple logo and black. I forced phone into recovery mode and restored to factory settings. This worked but still have the cellular error, therefore can't even activate the phone now.

I found this URL - https://support.apple.com/iphone-7-no-service/other-countries

Going to call Apple today and see what they say.

I will repost this because it seems almost nobody reads the older messages:

Steps:

• Settings > Mobile Data > Network Selection

• Disable "Automatic"

• Select your mobile network manually

• Restart the iPhone

After that, try to toggle airplane mode and check if the mobile network connection still works.

At the poster below,  Bug_reporter - dude I couldn't even get into the that menu when I got the error.

3rd update, for me the issue only pops up when roaming. Spend a few days in Belgium so on my "local" provider, no issues what so ever using 4G.
Now back in the UK, no connection on O2 or Vodafone, just does not want to connect. EE still same, connection but unable to receive/make calls, force to 3 and mobile data 3G works fine [unless 3 has no coverage in an area]. Still this does not solve the no service issue and should be a termp workaround.

iphone XS
iOS 14.2beta3 [because got a stable connection not sure of upgrading to beta4 unless I see someone that can confirm it fixes the issue]

This is ridiculous. Doesn’t Apple read our complaints? How about someone from Apple replying to us ? Nope . No care whatsoever. Useless piece of crap sitting on the desk now . We are all paying a phone line but can’t use it as a phone . Amazing !
Apple , i have always loved your products and have been a loyal apple costumer . This is about to change . You are clearly not concerned about all these peoples issues.
You messed our phones with the iOS 14 update , you need to fix it for us .

Same here: Spain Jazztel (omv) - XS 64

All work fine until I move with car seems like goes to no service and there is no solution, phone needs to be restarted. IOS 14.1 still having the issue. With previous versions never happened.

if you always have the 3G mode, this issue seems be solved but... i cannot suffer the speed difference

I’m able to resolve this by turning my phone off and on again, which is the reason I’m here looking for the proper solution!

I have iphone 6S with airtel sim. After upgrading to ios software version 14.1 . I am not getting airtel network. I have other android phones with airtel sim and they are working fine. Please look into this issue as soon as possible. At least provide us any quick solution for now.

Same type issue with both an iphone 7 and an iphone 8. After updating ios, cell service is constantly 'searching' and both phones only work now on wifi. Can't adjust cellular settings because there is nothing under 'cellular' when I look in the menu. SIM card ID no longer shows up in settings/general/about (although the carrier does). Also can't reset network settings. Phone freezes for a bit after trying and then resumes operation, but never shuts down (and it doesn't help). Daughter's iphone 7 started having the issue 3 days ago. Son's 8 started yesterday. Chatted and talked for hours and hours with Apple.. did everything they came up with and nothing worked. Double checked the SIM card registrations with the carrier and even put a brand new SIM in the 7. Still nothing.
Did a full restore after backup on the 7 and now it won't activate. Error message ranges from 'activation server is temporarily unavailable' to 'an update is required to activate your phone' (it's running 14.1.. fully updated). Hooking it up to my Mac, says activation information can not be obtained from the device. Have tried DFU multiple times. No change.

Have not done a full restore on the 8 because of what happened with the 7. But the 8 is showing all the same issues (searching, nothing under cellular, network reset won't work, no SIM info in about menu, etc). Would love it if someone has any other ideas.

I’ve tried out the solution suggested by Bug_reporter and so far my phone network has not been lost when using 4G

Steps:

1. Settings > Mobile Data > Network Selection

2. Disable "Automatic"

3. Select your mobile network manually

4. Restart the iPhone

After that, try to toggle airplane mode and check if the mobile network connection still works.

 

This fix may work but when you use Wifi-calling you NEED automatic mode as the "provider" switches from the main network to a "<operator name> Wi-fi". I live in a low signal area (which seems like a commonality for this issue) and my phone goes to Wifi calling in parts of the house. THIS is the trigger for it never getting back onto the main network (without reboot) when you leave Wifi. It is a bad bug as you have no idea your phone has no service, dangerous in some situations. Hope it is addressed very soon.

Have the same issue with iPhone 7 and 14.0.1 and 14.1.

Initially could get cell signal working by popping out the sim or going to manual mode... but now cannot get to the cellular screen. Reset network settings doesn't go through. Restart and DFU recovery don't make a difference.

my phone was working fine until i updated to the newest update which is 14.1 and my Airtel sim suddenly stopped working and the "no sim card inserted" and "searching" pop ups showing up... my primary sim which is Airtel works in other android or iPhones in my house which are on 14.0.1 but not in my phone... please let me know if there is any solution to this issue.
thankyou.
