Unable To Activate iPhone 7

I had this problem with Sprint iPhone 7 as well. Sprint cell services would not update/activate until iPhone updated with iOS update. iPhone wouldn't verify iOS update stating phone was not connected to the internet. I confirmed the iPhone was connected to internet via wifi, but iPhone still would not verify update. I could not get the phone to update through computer/iTunes either. iPhone locked up to the point I had to factory reset. Finally resolved the issue by powering down the iPhone 7, removed sim card, powered up, manual iPhone set up with no iTunes account only wifi, applied iOS update, insert sim card and reboot.

So, I had to send this phone in like a year ago, because of a "No Service" issue. This issue this time was masked with the inability to activate the phone, but it appears to be exactly the same problem that occurred last year. That problem was previously solved by sending the phone in and Apple repairing the phone and sending it back to me. I think the problem is a repeat of the problem last Fall. If this is not the case for your phone, some software update may have perhaps triggered it for the first time recently, since there are multiple people that have seen this issue in this thread. Perhaps someone else can confirm that this is the case for them as well. Or maybe, they didn't do a great soldering job on mine when they repaired it and the chip has become faulty for that reason.

I have the same problem, I thought that was an ios version problem then I updated and went worse now I connot activate it or access to my iphone, but I found this and I hope you can solve the problem.

I am having this issue too. I am thinking it has something to do with the chip that contains the iPhone device information. I am not entirely sure which chip it is, but while fiddling around, I tried restoring the iPhone to iOS 12 and iOS 11.4.1 and after many of those attempts, I frequently did not see the Serial Number of the device show up in iTunes. After installing iOS 12, it gave me a 4013 error, which if you google, you find a YouTube link about issues with the NAND chip some other chips. The serial number shows back up when I restore the device without manually setting which iOS version I want to restore to. See the link below. When I restore the device to DFU mode, sometimes it doesn't show on the iPhone itself that it is in iPhone Recovery Mode, but iTunes communicates with it just fine. Consistently with every type of setup: automatic from another ios 11 device, from cellular (cellular doesn't connect, instead it shows a Warning triangle sign and "No Service"), from Wi-Fi, and from iTunes. The apple support technician asked what would happen if you tried to restore through iTunes without the computer connected to the Wi-Fi. I can guess that would not work either, since the disclaimer for Connecting through iTunes says it needs to connect through Wi-Fi, but I will be trying that after I am done restoring it once again.

1. To check for network or activation issues and see if you need to replace your SIM card, contact your carrier.
2. Use recovery mode to restore your iPhone.

If restoring your iPhone still doesn't work, contact Apple Support.

this might sound weird but i had the same issue with my iPhone 7 and i actually fixed it but smacking the back of the with my knee as it was booting up on the apple logo try it & see if it works !

i had the same problem with my iphone 8 , with the new ios update to 12.3 it got resolved , u will have to be patient and keep trying . My iphone is on and was able to make 3 calls but again got the no signal sign ...

I too have the same issue.

Yeay, congrats!

So, IOS 12.0.1 just released and i tried restoring and downloading to this latest IOS. But the issue still persists.

I managed to find some guides on how to downgrade my IOS to the previous version but Apple stops signing the old IOS version about 2 days after a new one is released. So i am out of luck there.

But i did find another thread where people are having this no service issue relating to an IOS update (11.2.5), i think it kind of relates to the unable to activate issue because my phone is showing "no service" after the update too. So, long story short, someone in that thread managed to get a diagnosis on his phone and it turns out that the update fried the antenna band on his phone. I am not sure how that can happen. But could it be that IOS12 somehow created the same issue to some iphone 7?

Apple, if you are reading this, please investigate this? Thanks in advance.

Hey guys I own a repair and had a customer bring me a iPhone 7 A1660. Needless to say it had the same problems yall are experiencing and I got it to work took a little bit to get it done but it works.

I updated my iphone 7 to the latest ISO a few weeks ago "try too" and since then now I can't get it to activate. When I try with Wi-Fi it says "Unable to Activate" "An update is required to activate your iPhone". When I

try to do it with iTunes it says "The iPhone could not be activated

because the activation information could not be obtained from the

device". I have taken the SIM card out and put it back in, and it is

in correctly.

I went to Simply Mac today (certified apple support company) and the guy took one look at my phone, saw the “No service” in the top left corner, flipped the phone over and said that the device was an A1660 and that Apple had a recall on these devices. I am crossing my fingers. Apple sent me a box to send it off for repair. We will see what comes of it, but no guarantees at this point.

a dont want me to go though
