Help! Recurrent "activation required" message after upgrade to iOS 8.1

Well, add me to the club! :-( I have an iPhone 6, running 9.0.2 on Verizon. I got that exact Activation message about a month ago. At that time I input

my Apple I D and everything was fine. Then I was worried it was some kind of hack so I changed all my passwords on my phone. When it happened today, I decided to just shut down the phone and restart. When it rebooted, it asked me to set up iCloud but I just "skipped" the entire process. My phone is completely

fine and all of my iCloud settings were on. I can make calls and texts. Very strange. I may call Apple today. To me, it seems like an Apple issue. It hasn't happened as often as some of you describe, but it is annoying, and if it happens more frequently, I will certainly want the issue fixed... But at least I found a quick fix for the moment...

I have been facing this issue for a few months now. I was sent a new iPhone 6 (to replace my previous one) and that is what the problem started. Apple blames verizon and verizon blames apple. I have now at this point had 3 separate new phones and a new sim card. I still face this issue. The first time it happened my phone did not finally activate for a full week. Then it would happen on and off. I have called Verizon a few times on this issue. Ive noticed that if I go into a building that normally in the past had poor cell service the "no service" now will pop up and I am asked to activate my phone. I have traveled down to my families house for the holiday and now my phone has not worked for 3 full days. I am at a huge loss at this point. I don't know what to do. I am not sure if I should switch carriers. I really am going to be even more upset than I already am if I need to go spend more money to buy a new phone I already have. I mean it is so bad that the last tech person I spoke to a verizon just pointed the finger back at apple (one again) and when I disconnected the call she tried to call me back and left a message on my cell. Really.. lady... I told you for 45 minutes that my phone did not work. Someone has to figure out how to correct this. It obviously is a reoccurring issue.

I have experienced this problem quite a bit while traveling in japan w my iphone 6. I found that turning it to airplane mode and only using wifi solves the problem; it seems that when we are not in airplane mode then the phone is still looking for a connection in a foreign and thus unrecognizable place and then the little robot inside gets confused.

I Am going thru this issue right Now. I have restored, updated my Mac mini, updated iTunes, started as new. Everything the tech support has offered. All 7 of them. Now I can't get anyone to email me back. This issue started after I received a replacement phone from a repair. The most frustrating thing Ever. It's funny I see posts on the forum try all told me this has never happenEd before. has anyone found a resolution?

I work for a carrier and this is definitely not a carrier issue. iPhones activate on apple's servers and does not require cell data to do so. Most times you have to connect to wifi to even activate. This is an apple issue.

I have encountered the same problem with my iPhone 5S ios 9.3.3, I bought it second hand and it was unlocked. I tried to restore so that I could back up my phone. I tried activating with my new SIM and I got an error message "SIM CARD NOT REGISTERED". Then I inserted the appropriate SIM Card which is at&t. And now in the process of activating it, it never gets to the Home-screen. It keeps saying "Activation Required", I upgraded the firmware to ios 10.1 and still I get the error message "Activation Required" right when I click the "Get Started" which is supposed to take me to the Homescreen. Please any Solution??

I'm not sure why there hasn't been someone on apples end that has not been able to help any of us. However this is the solution that I have came to figure out. (Hope this helps everyone).

Go to:

Settings/Cellular/Cellular Data Options/Roaming/ then un-check International CDMA &/or Data Roaming.

I've un-checked both above and it was the only solution that I've figured out thus far to work.

Hi mine just recently started the same problem. It keeps telling me it's linked to "Find my iPod". Have you found a solution for this yet

im having same issue with my iPad. Problem started when I had iPad removed from Verizon data plan as I wanted to only use on home wifi. Do you think this is Verizon causing the issue?

How did you upgrade to 8.1? The only version signed for iPhone 5 is 10.3.

Hi PowerMac_G4. You need to pay attention to the dates of the postings. The original posting is dated October 31, 2014 1:57 PM, and iOS 8.1 was probably the latest version back then.
