iOS 14 no signal, no cellular data

Update: iphone 8 plus had cellular date connection problems that seemed to be resolved yesterday. Today not connecting again. Calling Apple support right now to get this resolved. Has something to do with IOS 14.2 update.

Once I downloaded the update for IOS 14.2 on my iphone 10Xs am having the same issue:

• no cell service with T-Mobile BUT texts were coming through

• I can restart the phone and it will come back temporarily

• have tried the airplane mode toggle with no success

• phone shows all bars for wifi, (wifi working fine on my laptop) but I cannot make calls over wifi even though this is enabled on my phone and always has been

• brand new SIM card

• Apple ran a diagnostic test and found a faulty antenna in the phone that was not communicating - got a brand new replacement phone yesterday.

• now texts are slow but still same issues with cell service/phone calls

• back to the same problems

anyone find a solution yet?

Yes same issue for me in iphone 7 and still exists, i don't have any VPN and using phone with lot of apps.. Can someone suggest any solution for this? Really critical and i switched sim temporarily to another phone for calls and messages alone which is really frustrating to use 2 handsets for apps and calls

iPhone 7 (recently refurbished)— cant receive texts/calls anywhere I don’t have Wi-Fi. Works on wifi.
It seems like this forum is active as of 12/13/20, as other people seem to be experiencing this issue. Would appreciate some help.

I have been facing the same issue since i upgraded to iOS 14. The issue still persists even with iOS 14.1 and iOS 14.2.
What i noticed is when i switch on my personal hotspot and connect my macbook then the network drop issue doesn't arise.
Apple can you please look into the same as it has been almost 3 months I have been facing this issue.
Whenever i travel i have to change the Voice and Data to 3G so that there is no drop in the Network Signal.
This means whenever i am out there is no Data.

Iphone 11 pro max
updates to ios 14.3
and nothing change
except modem firmware and carrier changed.
it’s so disappointing from apple
after stop production of 11 pro😔
what should we do?

I have an Iphone Xs and i updated to iOS 14.3 and it has been almost 4 hours that the Network Data has not dropped.
Keeping my fingers crossed.
I will update if the issue is resolved permanently post the iOS 14.3 update.

I'm following this closely. We have a pair of iphone X that have had an issue where previously 3 bars of service are now either 1 or none with calls dropping a minute or two into the call. We're with verizon and have called them multiple times, had a call with Apple where the devices were reset. The last course of action was that we bought a network extender and installed it yesterday. After we activated it, by calling Verizon tech support, there was no improvement in cell service. The ticket was bumped up two tiers and is currently in the advanced technical support and in a pending status. They are going to attempt to get the network extender to produce better signal. This really seems like it HAS to be an iphone IOS issue.

I'm actually just the administrator of the business account, the two users with the problem happen to be the Owner of the company and his wife. It's not great to have the owners phones not work. This has been going on for weeks with noone admitting any fault or errors.

I'm waiting to hear if an update to 14.3 helps, and also waiting to find out if Verizon can magically make the network extender (that we purchases through Verizon and wasnt given to us for free) work.

Same issue. I have done reset network settings multiple times. Deleted files, left the iphone off, dusted off the SIM card. Also now my phone slows down to a grinding halt, then, if i pressed buttons or performed gestures while frozen, it does than all at once after a long delay, then freezes again. I am only using half my memory. So its not storage issues.

The issue seems to have been finally resolved with the iOS 14.3 update.
As mentioned earlier I have a Xs.
I updated to 14.3 yesterday and since then there is no loss in the Network even once.

We have 4 IPhone in our household, 3 XR and an XS. After 14.2 update, my XR was the only one with this problem. After losing service/network, sometimes it would recover on its own, but most times I would have to shut down phone and restart it to regain service/network. Patiently waited for 14.3 and installed it yesterday (121420) and so far, fingers crossed, it has worked. Haven’t lost service or network yet, will update at later date.

1. ...signal was fine overnight and BAM just lost it. Not even 12 hours.

We installed 14.3 yesterday on our problem iPhone X's. It did not help. The phone is useless as a phone.

I feel iOS 14.4 Beta 1 will fix the issue on iPhone X as finally there is a modem firmware update!

I have a IPhone XR and when I installed IOS 14.3, my cellular got locked by the update! PLZ help
