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!

I just got a notification on my phone that say it needs to update my carrier settings. I have version 11.1.1 already and am not experiencing any problems, but after reading these comments I don’t think that I will be updating to these new CARRIER settings. Is that what your phone displayed to you when all this trouble began?

Nov 19, 2017 11:30 AM in response to cher806

Well I don’t wanna point any fingers but I updated my phone to 11.1.1 and my phone was working, when I updated the “carrier settings” is when my phone started the endless searching/no service, so take that however you wish. I did upgrade my phone so I wasn’t too worried but I still had no service for about a week straight. Not even the new SIM card helped -_____-.

I have not tried or looked to use VoLTE. MintSim is under T-Mobile, I will check to see if they offer it. Also, I talk to MintSim Support, he ask me to call back when I have the phone and he will do a refresh through the tower. Not sure what means, but I have to take the SIM card out for 3 minutes. I will also ask about seeing her phone on the towers.


Right now, when my wife left, it was intermittent service where it when to No Service, I would switch to Airplane mode, wait 10 seconds, then turn Airplane mode off. Then I would turn off the phone, wait a few seconds, turn the phone back on and she would have service again for a little bit.


Not a good solution but might be helpful in a pinch. I will check on voice over wifi too.

I'm having the same issues did everything that can be done that was suggested and even got a new sim card and of course Verizon wants to sell me a new phone. I'm not paying for my iphone7 because of a previous promotion so it would increase my bill 35 plus dollars to upgrade. My phone was working perfect and is in pristine condition before all this stuff went down. ANY NEW NEWS YET???

Nov 25, 2017 6:19 PM in response to liv0123

An update... after upgrading to 11.1.2, performance is better than before, but I’m still experiencing moments of “Dark Territory” when I’m out and about - not as bad as before, but it still happens in areas where I didn’t have a problem before.


Overall, my phone is not getting as hot as it was before, but battery performance is still worse than what it was before the initial October Carrier update. I’m hoping that another update follows soon (either iOS or carrier) to help alleviate this more.

Nov 25, 2017 9:59 PM in response to jcchaconjr

So, some good news jc & definitely great about the device temp but yes, I too am awaiting an 11.0.3 update as I found out my nan still has some of that too still ...the "dark territory" moments but didn't want to bother me. I must get them to refresh towers every day & I have them wait on the line with me or I feel they're just saying they do to be honest 😔 It's odd most of it is at&t? :/ or am I just thinking this?

They say she's on LTE but it rarely shows I've found out.

I cleaned up her phone a bit more too which helped.

Thinking about getting battery replaced too...she still has original one in device

*Crossing fingers update out soon*

I really don't think your problem with your ipad is related to this issue, but I'm glad you were able to sort it out.


It's really sad that Apple have completely ignored this issue. The support staff at Apple insisted that it was just a faulty device and nothing to do with software. It was an unpleasant week or so and pretty absurd that I had to replace my device just to get service again.

Nov 26, 2017 11:23 PM in response to Calvin_Bonny

Hi Calvin, I agree. I spoke with a few carrier techs today. One explained that if network settings have been reset on the iPhone, then he could reset a customer's settings on his end and refresh the tower. I explained that when we turned her WiFi off, the call got really scratchy then ultimately inaudible & her bars would go no higher than two and she lost her LTE coverage as well. He called her personally to assist as it was in his court at this point, plus she needed help asap. Again, call became inaudible so I couldn't even help her turn her WiFi back on. I'm Checking back tomorrow to see what the end result was

Nov 26, 2017 11:35 PM in response to TAL95

I wish I could offer help, but I only came here to say that I am suffering from the same problem. It has been just about 2 weeks for me without the ability to send or receive calls or texts through my wireless carrier. I personally have been able to turn on Wifi calling, but that only works in my home and makes my phone completely useless as a phone.


I wish Apple and carriers (Verizon in my case) would own up to their mistake and tell us what is going on and when we can expect a fix. Instead they are both insisting that there is a physical problem with my phone and I should buy a new one. I just want to encourage everyone not to buy a new phone from Apple to fix this problem that they created. I am nearly positive this is a software issue, and personally find the idea of rewarding a company for their mistake by giving them more money to fix it revolting.

Since I updated to ios 11.1.2 I’ve got No service, my

Phone was working perfectly, it’s out of warranty even so I went so tecnic support abd tried every singke recommendation, the people from apple say it’s a hardware problem but till that day my

Phone didn’t have any issue, a tecnic checked my phone and it was in perfect condition... now they tell me to wait for the update or to pay for an upgrade !!!! It’s just insane, went to my country industry department to put a complain, Apple can’t expect me to be happy not knowing the reason my phone stops being a phone ..... really dissapp

Nov 28, 2017 12:40 AM in response to Nightmoonstone

So, an iPhone 6 came my way. Boost let him leave the store with no service/searching

He has 10.3.3 on device still and it's happening to him also.

Did all troubleshooting. Still didn't help.

He's going back to carrier tomorrow for possible replacement

Think I've cursed myself btw. I have a galaxy s8 plus and am now having this issue periodically. Frustrating 😑
