Since updating to iOS 17.5.1 I have no service!

If only one network provider’s service lost on iPhone (assume there are no other serious bugs that can only solved by reset device) after update to 17.5.1, then it makes sense that the problem may is network provider. But now since there are many discussions that people with different network providers said they lost service after updated to 17.5.1, then it is clear that it is a new serious bug introduced by Apple, this is even not count other new serious bugs (like App Store unable restore in content restriction settings).

I just feels that mostly all systems around the world include iOS just all followed Windows’s trend: adding new features and fix previous bugs to enhance user experience, but also adding multiple bugs at the same time.

I had the same issue on my iPhone 14. With as many complaints on the update of iOS and considering there were no issues with the iPhone before the update I would consider it was the update that created the issue. I had a diagnostic test and was told it must have had problems before the update. I don’t agree. I had to replace my very expensive phone with another very expensive phone.

i have the same problem, it occurs few days after updating to 17.5.1. previous it was perfectly fine until the update. i cant receive any signal. device not reading my sim card. i have try network reset and factory reset but the problem still persists. have bring the iphone 14 pro max to authorized dealer and they suggested me to inspect phone for the problem, which will cost for me around 25 usd. they also suspect motherboard problem and the cost for motherboard around 700 usd ++. This is totally unacceptable as my phone have not been any damaged or accident, just after the update the problem happen. fyi ive tried my sim card on others phone and its working perfectly. this is frustrating. any update or reccomend here since the phone already out of warrranty.

Same issue here. I have an iPhone 15 pro, my husband and son both have iPhone 11. All 3 of us are on iOS 17.5.1 and all 3 of us are experiencing lack of cell service (SOS only). My daughter, who is on our same cell phone plan, has a Samsung and is not having any issues.

since my husband and i updated to ios 17.5.1 we have no cell service in the house. at first we thought it was his phone, since I was gone for a week. so he bought a new iphone 15 pro max over the weekend. new phone, same problem. now that i'm back home i have the same issue with my 14 pro max. we get calls and can hear the caller, they can't hear us. takes going outside and restarting the phone to get 2 way talk. neither one of us had this issue in the house before the update. i work from home, so cell is my only form of communication. none of the fixes noted online worked. anybody find a work around?

My iPhone 11 updated two days ago. I had no service at all for 36 hours. I restarted the phone about 50 times per Verizon’s recommendation and it found a network twice in the last 8 hours, both times for less than 5 minutes. Obviously the update is the issue.

Same here. I can occasionally make a WiFi call, and can use FaceTime Audio but all other calls get "call failed" or will simply not go through

I seriously doubt it's just a coincidence that we've all started having trouble making calls since this update. WTF, Apple?

Hi. In my case it was showing SIM failure right after the update 17.5.1. It was resolved after I replaced old SIM with new one. Thanks to Team Apple for support!

Dude everyone is having an issue since this latest update if their phone is 13 or below. That points to update issue.

I’ve had my phone checked. No hardware issues. The sim was replaced and network came back, however, messages and FaceTime are still not working. That is definitely a software upgrade issue.

Samething has happened to my fiancés iPhone 12 Pro Max. He did the new iOS update (17.5.1) last night an ever since then his phone says no sim or invalid sim. He’s unable to make or receive calls. He called our cell provider an they said that none of his information is connected to his SIM card. WTH?! So they have to send his account to another department a they’re supposed to get in touch ASAP! I hope they fix this issue because it’s BS!!!! Good luck!!!!

I performed the 17.5.1 Update almost 2 weeks ago. Ever since, several of my apps have stopped working. My phone will not shutdown at times. The battery is draining (I’m not running out for an upgrade). My texts messages won’t load at times. My emails arrive but I can’t download and view them. I have another iPhone under 17.4.1 and am not having any issues at all. My issues started the very moment I downloaded 17.5.1.

I don’t think the SIM are the trouble. I also changed one of my two SIMs and few hours later the second SIM on a different phone had failure.

I have to remove the SIM then replace but can’t trust it.

Hello, I have the exact same problem on my iPhone XR since I upgraded to IOS 17.5.1 (no service)

I tested two different sim, wipe complete with my phone
