iPhone keeps saying "no sim available" after IOS 16.5 update.

So, this happened to me out of nowhere, as well. A reboot would help it for a couple of days and I would get it again. Then, it started being more frequently....I opened the sim card and reinserted. Again, fixed for a very short time. Then, I reset the network settings and it helped for maybe a few minutes. Truly bizarre. After a few times of doing the last, I went into settings and there was NO sim information AT ALL. GONE. Eventually, nothing worked and it was constantly on SOS. On Christmas, I did a chat with a rep from Verizon. He sent a QR code to my husband's phone, I scanned it...followed the prompts and VOILA! Fixed. Haven't looked back. Apparently, there are eSim cards on iPhones after 2018. *shrug* I don't know...but the reactivation worked and I am good as new. For whatever it's worth, I am on iphone 12.

Today a pop up came stating no sim and after I clicked okey it isn’t working says no sim available.

No sim damage also even tried re starting which isn’t really working.

I am currently experiencing this. My carrier told me that now have to find time to go to their store and pay for a new sim as this is "not their fault". she actually laughed at me when i questioned why i not only have to find time to come in there for her to fix something that is not my fault, but also pay for this? She then laughed and told me it wasnt Verizon's fault either and if she wants me to fix it I will have to pay. I let her know that it sounds like i have no other choice at this point and hung up. GRR.

Verizon corporate stores don't charge for SIM cards.

1 hour ago, everyone’s iPhones at work suddenly said “NO SIM” all at the same time. Different carriers, different models of phones. Some personal phones, some business phones centrally managed. The whole building had to manually reboot their phones to get the devices back to normal. What is up with this?

There are probably microcells that serve your building that are connected to the same power source which was interrupted. Carriers often co-locate on infrastructure leased from third-parties. Lots of office and retail buildings can't get signals without the microcells. All it would have taken was momentary glitch.

Ironically, when I worked for Verizon, you couldn't get a signal in most of the stores if the microcell went out.

Again, if this was the company you work for and it happened at multiply company sites, it means that something went wrong with a system that your company has. It happens. If it had happened to everyone who had an iPhone, it would have been huge news.

Multiply this times hundreds of people in different areas / different cell towers / different carriers / different makes and models.

If there had been some massive failure of iPhones, it would be in the news. Something local, specific to your company's physical locations, perhaps, seems to have had a glitch.

As of last night I also cannot use the remote app on my iPhone(s) to connect to any of the Apple TV’s in my house either.

Is your ATV connected to ethernet? Or WiFi?

Good idea. This just started happening to me yesterday, seemingly for no reason. Restarting only temporarily resolved the issue. Ejecting and reinserting the SIM also only temporarily resolved the issue. If the issue continues today, I’m going to try the tape trick to add a little thickness to the SIM in case it’s a loose SIM/poor contact issue.

Hello guys. Same issues.

I have an iPhone 13 with the last iOS Update,

SIM card and eSIM are installed. It works well until you switch off the phone. When you turn it on there is no SIM or Signal for both.

But if you remove SIM, reboot the phone, and then insert it, it works. But for eSIM you have to install everything again from scratch.

And when the phone is switched off again everything is repeated. I don't know what to do. My iPhone is new, I just got it a few months ago.

Happening to me as well. All over the last week. It mostly seems to occur over night and when I wake up in the monring and grab my phone I can't get texts or calls. Or make calls. I have to shut my phone down and restart it. Very annoying.

i switched to an E sim after having this issue with a physical one. fixed for about 4-6 months but then 3 months ago started doing the same thing. “No sim card detected” and imessage doesnt work until i go into settings and turn on imessage again. It isnt a huge deal but its super inconvienent

I am having this message “no simcard and “SOS” displays on the screen every now and then after updating to IOS 16.5.

Unfortunately I already did all that. Just shy of doing a full wipe of my phone and erasing everything.

Have you gotten a new SIM from your carrier?
