Hi!
I've installed iOS beta 4 on my iPhone 11 Pro and since then, I lost the signal and I don't have data. I have another iPhone X with iOS 14, and I don't have issue with it. It only occurs on iPhone 11.

I tried many things like:

Reset network setting
Turn off/on airplane mode
Turn off/on cellular data
Hard reboot
Soft reboot
Reset content and data
Turn off/on roaming

...
Same issues
It seems that the cell is looking for the signal constantly.

Do you have any idea how to fix it ?

Just wanted to add that putting those two sims on an unlocked iPhone 11 running 14.4 also resulted in no data connection. The phone shows Hello Mobile 3G and data is not working.

Hi there,

I have been facing the same issue after upgrading my iPhone 8 to iOS 14.4. The mobile network is either very low or mostly it shows no service. The network shows up once or twice in a day but still I’m unable to receive or make calls nor receive any text messages. Whenever I place a call, the available network turns to no service. Tried consulting the apple support on this but they aren’t aware how to resolve this. They would just simply tell me to try rebooting or reseting the phone.

This issue of fluctuating 4G signals started around 6 months back for me when I had upgraded my iPhone 8 to iOS 14. Until the past two weeks the 4G was fluctuating but after installing 14.4 its even worse and shows as no service.

I, too, am experiencing the same issue with 14.4 on XS, two different phones. Any word from Apple or Hello Mobile?

Iphone 11pro, iOS 14.4, provider Vodafone UA. Issues with network too. I have installed 1 physical SIM and 1 eSIM in my phone. The issue occurs for the SIM card where cellular data (3G or 4G) is enabled. Issue happens periodically, can occurs several times per day. The signal bar can show 2-4 bars for related SIM, but it's not possible to receive or make calls, use mobile internet nor receive any text messages. If SIM has mobile data off - it's possible to make calls all the time. Rebooting helps. Switching on/off air plane mode - sometimes can help, but it requires 3-5 cycles of turning on/off. Manipulating with different cellular settings or resetting - doesn't help. Only switching off mobile data for related SIM helps.

Removing the VPN connection worked for us. Needs fixing of course.

Still the same ios 14.4 on iphone 11 pro max. Already 6 month using hotspot from another phone. Very hard and waste time to search gsm network with airplane on/off. After getting the gsm netrowk, even more difficult to get the 3g or LTE network. Very disappointed to apple can't solve the problem after 6 month. Maybe i will change the cellphone soon, not use apple product anymore.

Same thing here. Yesterday I removed Norton AV and for 1 minute I had connection but suddenly again the NO SERVICE message. I also have an old iPhone 5s and is working fine. I have a iPhone 8 Plus, IOS 14.4.1. Tried using another SIM card and same thing.
Besides the Norton AV, what other app could be bothering??.

Thanks,

Hi,

I also have this problem. Just bought an iPhone X a month ago. Ever since I’ve installed iOS 14 it keeps saying “Cellular Data Not Subscribed To Data Network.” It worked prior to the update 2 weeks ago.

I have tried all of the following:

Called service provider
Reset network setting
Turn off/on airplane mode
Turn off/on cellular data
Hard reboot
Soft reboot
Reset content and data
Turn off/on roaming

My phone is practically useless now. Which sucks because I have to use it while working from home.

Same issue with iPhone 12 mini, location - Ukraine. 4g is very unstable and doesn't work in 90% cases, have to use 3g instead

After Installing Version 14.4.1 on my iPhone SE 2020, my mobile data became really slow, It takes around a minute to load a page, and can't load more than 1-2 photos. I tried to reset the network , restart the phone multiple times , insert sim again, but nothing helps. When its connected to the WiFi network it works fine. Please Look into it and fix it as soon as possible, because the phone is unusable as it is. Thanks!

I have just updated my iPhone 11 to the iOS 14.4.2 last night and my phone suddenly stop working. It at first said I had no data and when I went into my mobile settings to check, it took me out and a pop up said there was no sim. I have checked my sim and everything. I don’t know what to do!!

Good evening everybody.
I have an iPhone 11 Pro and have updated it with IOS 14.4.2 too, on the day of its release. Since then I get SIM Failure messages and therefore can’t connect to my carrier. I have tried to reboot or use the default network settings but the issue remains. My SIM works in a different phone so I believe the 14.4.2 version is at fault. I hope a fix for this very annoying problem is being worked on.
Would anyone have another solution in mind? Thanks.

Hi Everyone,

I had the issue of not being able to use voice, cellular data & WiFi on Iphone 12 pro, IOS 14.4.1, carrier - Visible. Problem started after I flew back into the USA. Tried all the usual steps like resetting network settings, deleting Nord VPN App, pulling out the SIM and rebooting which suddenly got the WiFi and voice calls to work. To get Cellular data working , I tried to toggle between the 5G and 4G cellular data options, filed a complain with carrier, updated to IOS 14.2.2; none of which worked. 2 days later digging into every setting on the phone, I found a profile “unlockit.co.nz” under General > Profiles & Device Management. Couldn’t find this on my other iPhone so I deleted the profile and rebooted the phone. And cellular data started working!

Hope this helps!

IOS 14.4 iphone 11 pro not picking up to LTE. Prefers 3G even though my other iphone is always LTE in the same place. Please fix this ASAP. I suggest at least to have a way to force the phone just to LTE for data.

A couple of days after upgrading iPhone 7 to 14.4.2 I lost phone connection, continual searching for a signal. Sim was ok in an older phone (old SE also with 14.4.2!).

I tried most things mentioned here: Couldn't try going to 4G since Cellular said it was in Error. Couldn't reset network settings (just froze). Couldn't restore to earlier iOS (unsigned). Deleted VPN apps, reboot, toggling airplane mode. Nothing worked.

I upgraded to 14.5 beta 7 and it's back! (I immediately went to 4G just in case! And switched off auto update!)

With 14.4.2 it took a couple of days before I lost the signal permanently, perhaps after driving around(?). So I might lose it again.

I am having the same issue.
Upgraded to 14.4.2 OS today morning. Since then my mobile is not receiving signal.
Always searches for signal and some times throws error saying "Your iPhone cannot make and receive calls or access mobile data until it has been updated".

Anyone has any solution for this?

Update: Lost signal again after a week or two. Changing iOS didn't help this time. I suspect it was associated with me travelling with the phone, in and out of areas with a signal.

Finally found a solution for flucking lte!

Specifically for my SIM Mobile Data Network APN settings were not fetched automatically for some reason.
After setting them manually lte works as it should.

Settings -> Mobile Data -> Mobile Data Network -> APN
For all APN fields set internet
