Additional 17.4 and 17.4.1 problems

I've also tried everything. Apple ran diagnose and said it was a hardware issue and had nothing to do with the update. When I put my SIM in another phone, SIM worked just fine. Also tried settings and all on my phone. Eventually I connected my phone to Itunes on my computer. My computer informed me that I needed the update that was already on my phone and not available on my phone anymore. So I ran the update from the computer. First it said no sim. Then I ejected SIM and put it back in and I finally am now up and running again. Truly hope this helps others persons as well.

In addition to what razmee209 has already said I would like to add...

Reset Network Settings: Go to Settings > General > Reset > Reset Network Settings. This can fix connectivity issues like Wi-Fi and Bluetooth.

Apple store will perform a DFU restore. You'll have issues if you don't pay for the premium iCloud service and problems with eSIM too. Even then, that might not be a fix. It's a gamble.

As such, my rule of thumb (which I admittedly don't always follow) is wait a few months after an update is officially made available before downloading.

I had a bunch of errors as soon as i downloaded this update, I couldn’t sign into my App Store apple ID in general. I disabled the new “Stolen Device Protection” feature, and my phone went back to normal.

best of luck

If you don’t have a computer with itunes, maybe try to go to an Apple store?

I finally found a solution to this!

go to settings-> General -> transfer or reset iPhone -> reset all settings.

Apple Support told me to reset my Network settings. It worked.

I contacted Apple. They told me to clear my Network settings. So far this has stopped my issues with not getting phone calls. I am having issues with my apps not working, so I had to reinstall them. I still called Apple back, and put in a complaint that everyone I know that has an iPhone is experiencing different problems since this update.

When you try to turn the phone off, press the buttons long enough yo turn off ONLY ONCE and make sure the screen doesn’t turn off for about 5 minutes. That’s about how long it takes for the turn off option to appear in my phone.

A possible solution for your draining battery, under Settings turn off background app refresh under each app.

Hello. Iphone13miniuser. I have also heard of this. I can almost guarantee that this won’t cause permanent damage to your phone. If anything you might need to get a new SIM card. If for some reason you do need a new sim card then I would think this would be funded by Apple due to their update causing this. Unfortunately from what I see there is no real fix besides trying to clean the SIM card with a couple drops of alcohol. If that doesn’t work then I would recommend first reaching out to your cellular carrier. As an experiment if you know someone who doesn’t use your carrier then you can try to switch SIM cards with them. If none of those work then I would reach out to Apple. They’re very good with all that stuff and making sure you are satisfied.

Hope this all helps.

My Dad's SE3 is doing the same thing when updated to 17.4, it reads NO SIM. We contacted the carrier and after a long "try this" session it started working again, for about a week and then back to NO SIM back to the carrier and finally got it running again. When 17.4.1 came out I thought finally a fix and updated it for him, NOPE, broke AGAIN. NO SIM, phone call to carrier again and after another hour and a half of "now try this" it was working. He went back to his house and in 4 days it was back to "NO SIM" This is crazy, my Dad is 83 and NEEDS his phone for safety purposes. We choose Apple because we thought it was better, I am now second guessing our choice. I will not be updating my phone any time soon. Apple do better. The nearest Apple store to us is nearly four hours away.

Same issues here. Updated to 17.4.1 last week on my iphone 14 because my watch had stopped connecting. Immediately after the restart from the update my phone had to cellular data which means it's basically a brick. I'm 17+ hours in with Apple, Verizon, and an Apple store over the last few days. No solution. Apple says the phone is fine, Verizon is out of ideas. Things we've tried multiple times...restarting, turning off/on cellular data, changing and resetting network settings, multiple new eSim cards, factory restore, and updating through a computer instead. Nothing has worked and I'm without a phone at home with a 3 week old...I'm pretty sure I'm giving up tomorrow and buying a new phone (not an iphone after 10ish years).

Running iPhone 13 model A2482. My phone was running smooth and great. As soon as I installed iOS 17.4.1 everything is choppy and delayed and if I try to play a game my phone gets hot and the game is also stuttery. Rebooting my phone can help for about 10 minutes and then it continues to get worse again.
