No service after iOS 11 update

iPhone 6 Plus getting searching or no service. I can make phone calls/iMessage while on WiFi. I’ve tried these steps:

1. Turn on/off, hard shut off as well.

2. Turn on/off airplane mode, cellular, LTE, roaming.

3. Reset network settings.

4. Reset all settings. (Worked for a day only).

5. Update to 11.1 iOS and 30.1 carrier update.

6. Check time and date settings.

7. Took out SIM card.

8. Took off case.

9. No water damages.

10. Restore (Worked for a day).

Looked at multiple sites and so far it still says searching. AT&T account is good. I have 5 iPhones on my account and they have not updated and they still work. (iPhone 5s, 6, 6, 7, 7). Trying to avoid going to the Apple store as I know they will probably throw a $320 charge as I’m out of warranty. Any tips is welcomed!

This is my experienced SOLUTION for the intermittent and consistent "No Service or Searching" and Cellular Data/Cellular Network connectivity issue on one of my company’s mobile device. Problem was not a device software/hardware issue, which is especially demonstrated for those who have a new device or have performed a full device reset. Apologies in advance for the lengthy reply and hope this steers you as well as others towards a permanent resolution.

Device Information was incorrectly logged in the wireless carrier's system.

Step 1 - Accurately confirm your Device Information. First, go to Settings>Phone to view My Number (phone number). Second, go to Settings>General>About to view the device's Serial #, IMEI, ICCID, etc. IMEI=International Mobile Equipment Identity and this 15-digit serial # differs from the manufacturer’s serial #. ICCID=Integrated Circuit Card Identifier and this 20-digit # directly references the SIM card that's physically installed in device’s external port.

Step 2 - Contact your wireless carrier and ask them to verify that pertinent device info is respectively aligned. Just an FYI, a carrier’s system may demonstrate info correctly, but a refresh of info may be required in their system so that correct functionality is stimulated. ASK THEM TO CLEAR OUT ALL OF THEIR LOGGED FIELDS FOR DEVICE INFO AND RE-ENTER THE INFO. They should also ask you to power down your device during this process. Begin with the basic info assigned in their system, such as phone number and iPhone 5, 5S, 6, 6S, 7, 8, X. Next, confirm the serialized type info. ICCID is critical. Be prepared to replace the carrier’s provided SIM card should the ICCID not match their system. Once device is powered up and is functioning correctly through cellular service ONLY, it’s also a good time to ensure that the Visual Voicemail is functioning. You or they, using another phone, can leave a test voicemail.

***Resolution steps above makes assumptions of mobile device general readiness.***

Refer to https://support.apple.com/en-us/HT201415. I’m sure I’ve missed some, but a few examples of readiness are as follows:

•

Device isn’t damaged.

•

Device appropriate SIM card is correctly installed.

•

Device cellular is turned on and cellular settings within device are correctly configured.

•

Device software is updated to iOS 8 or later version.

•

Device is manufactured specifically for and/or approved for use through wireless carrier.

•

Within wireless carrier service area and no cellular outages.

•

Wireless carrier account is in good standing/active and there isn't service type block referencing your device's IMEI. Blocks/blacklisting logged by wireless carrier can be from device reported as lost or stolen.

•

Carrier Settings update has been installed on device. If cellular or Wi-Fi service is available when checking Carrier version installed, you’ll see a pop up window for a Carrier Settings Update Available. Go to Settings>General>About and wait a few moments. Apply this update whenever it’s available.

Cheers & Good Luck!

John

Wow, add me to the list of users whose posts Apple is deleting on these boards. As much as I want to give them the benefit of the doubt, that kind of behavior leads me to believe that they are hiding/not acknowledging a problem. I'll do my best to recreate the post here, but I'm sure I'll be missing some critical info:

Spoke with someone from Engineering who assisted me in sending log files for the No Service issue on my 6S. I was very clear that I live in an area with spotty service, but would be travelling to an area with 100% coverage soon. I captured additional logs in the "good coverage" area, but when I offered to send them, I got a polite "thanks but no thanks".

Also had an appt at the "Genius Bar" where they looked over my phone, pronounced it is excellent condition and were willing to give me $150 credit towards a new phone. Unfortunately, a new 6S is $300, and new 8 is $799. My phone was paid off. I can't afford to drop a couple a bills on a new phone, and it's really annoying that Apple seems to think I should, even though the phone was working great before ios 11.x, and is not now.

The entire reason I am with Apple is because by being responsible for the hardware and software, the devices are supposed to be more stable. If that is not the case--and they are shadily deleting posts with complaints--then there really is no reason to be loyal. What a shame.

P.S. I'm saving this to notepad so I can easily re-post it if (when) it is deleted again.

Apple finally released repair instructions February 2, 2018. The only repair is replacing the phone. They finally replaced our second phone. Not the first one since I bought a new one to replace the first one.

First call Apple and speak to a Senior Advisor. Because they are the only one that can troubleshoot your phone, and send you a new one. They know about the “No Service”. They also know that it will eventually go into restore.

Second, they can either mail you one or schedule you an appointment at your nearest Apple store.

I chose apple store because mail ment that you have to mail yours first then get the new one.

Third, when you go to the store, they will find all the comments of the senior advisor, and do their own test as well and replace your phone.

That’s what I had to do.
