I upgraded to iOS 11.0.3 from 11.0.2 on my iPhone 7 Plus the evening of 10/17 and by the afternoon of 10/18 my phone will no longer connect to the ATT cell network despite being in many different locations that normally have strong cell service. Anyone else running in to this problem?
iPhone 7 Plus, iOS 11.0.3, just upgraded from 11.0.2
Hi
I’m having the exact same issue with my iPhone 6 after updating to iOS 11.0.3. Tried all the troubleshooting steps I could find and spent an hour on the phone with Apple trying to fix the problem.
I think I found the solution by accident. My phone is under a third party warranty and I needed to turn off find my iPhone before returning the defective phone. After turing find my iPhone off and wiping my data from the phone, the cell service was restored. Of course I restored the phone from iCloud and some time later would lose the cell service again and try all the trouble shooing again. So far turning off find my iPhone and restarting the phone has been the only thing that will restore cell service for me.
TL;DR Try turning off find my iPhone and restarting your phone.
Are you guys running on iOS 11.0.3 ? I asked a friend and he's running 11.0.2 and everything seems to work fine. Im assuming iOS 11.0.3 update caused this issue. I hope the next update iOS 11.1 will fix this problem.
Hello, I have the same problem, after update to 11.0.3 passed 5 days and my phone doesn’t catch signal... it says searching.... I reseted it, restored it with a backup and nothing worked.
I decided restore via iTunes with a clean iOS... now I can’t activate my iPhone because is necessary cell network to complete the activation.
I hope that the iOS 11.1 resolve this problem.
PS - if you do get it activated, please let me know if the problem is fixed. I suspect it is connected to a Setting (e.g., like Find My iPhone) that I have that is different from the defaults since this issue does not affect everyone. Unfortunately when it takes several hours for the phone to fail after the upgrade, there is no way that I am going to be able to test each Setting change separately ☹!!
I tried it several times and just it says “error while connecting to activating servers, try again later”. Even if the phone is connected to the laptop to do the activation via iTunes the result is the same...
my ideas are over, I don’t know what more to do... so my last hope is the iOS 11.1
I contacted Apple support via Twitter and they said that I should get the phone to an Apple Store in my country to be inspected.
cheers!
Thuis has happened to me. I lost cell service, went to att asked for new sim...same issue... then called apple, went through hours of following their instructions of restoring/starting my phone from new...NOTHING... Apple replaced my phone....SAME THIING AGAIN...Went to apple store where they were understanding and restarted my phone from new...worked! A few hours later same thing...no cell service. Now I am waiting for apple to call me back
This is an issue with apple's new update, NOT YOUR PHONE
Mmm... Today with ios 11.1 my phone still searching... tomorrow I’m going to buy a new phone, clearly not will be an iPhone
I hope someday my iPhone 6 comeback to work normally
cheers and good luck with this thing!
What iOS version were you on? I tried to install iOS 11.1 today. First tried downloading it over WiFi directly to the phone. It downloaded but then the phone could not verify the update saying that it was not connected to the Internet when it clearly was.
I called Apple tech support and they had me try iTunes to apply the update. Waited an hour to download the 2.64 GB and then installed only to find the installation quit with “unknown error 4000.” Next we tried to restore the phone from a backup and this failed. Finally tried to erase the phone completely and install a fresh version of iOS 11.1. This failed with “unknown error 51.”
At least before it worked on WiFi, now I have a brick after trying to install 11.1 The phone just shows a restore from iTunes picture and does nothing.
Heading to the Apple Store tomorrow AM, but based on l1magz notes above that may not work either. Would really like to know if all of your attempts above were with 11.0.3or if you tried 11.1 as well. There is nothing in the 11.1release notes that says anything about cell service fixes unfortunatel.
PS to l1magz: After Apple replaced your phone, did you go home and restore your apps/data from a backup? Did you go into Settings and change many settings from the defaults?
I remain concerned that some setting change may trigger this problem. When I was on iOS 11.0.2, which did work for me, I turned off Siri in all of my apps and then later decided to turn off Siri completely. This didn’t cause a problem in iOS 11.0.2, but I am wondering if it might have tickled a bug in 11.0.3. Is this possibly a setting change that everyone who is having this loss of cell service problem did?
I am going to the Apple Store this AM just to get the phone erased and get a clean version of iOS installed. I then plan to not make any further changes other than reinstalling directly from the App Store some of my most crucial apps like Google Maps, Weather Channel, setting up my email accounts, and reconnecting my Apple Watch (original version). Will then let that sit for a couple of days and see if things continue to work before making further changes.
It would be really helpful if other people would provide more details of their environment to see if there is a common thread. As you can read in other problems above, there are people with iPhones ranging from 5-7 Plus using ATT that are not having cell service loss, so some setting change from defaults or app installation must be to blame.
Thanks in advance!
After I received my first replacement iPhone 6, I went to an Apple Store and had them setup the iPhone as a new phone. I downloaded my Apps from the App Store not from a backup. I reset my preferred settings manually. The iPhone cell service worked overnight but the “searching” returned in the morning. After contacting Apple directly, the Apple tech replaced the iPhone for a second time.
The 2nd replacement iPhone 6 arrived yesterday. Again SI set it up as a new iPhone and repeated the process of downloading apps from the App Store. I connected it to iTunes for my music. So far it’s only one full day and all is well.
I will give an update after a week or so.
The steps have all been followed. The only additional step is to speak with a support rep...but I don't have cellular service to do that.
WHAT FIXES THIS ISSUE?
Pixel2 here I come...
What happened when you spoke to a manager at the Apple Store and demanded that they fix your broken phone?
Are you saying that Apple refused to fix your phone?
Thanks ! It worked out for me !
My iPhone 7 Plus was working fine on 11.0.2. It was the upgrade to 11.0.3 that caused the cell service loss.
Sorry to hear that you are also affected by this bug. You should be able to activate your phone on a WiFi network. If you don’t have one at home, go to somewhere where WiFi is available.
iOS 11.0.3 upgrade torpedoed my cell service?!?
