No Service after iOS 17.0.3 Update

I just had it happen. I powered off and back on and cellular data is working now.

Have you tried powering it off then back on? That worked for me.

Switch off VPN, which is switched on in update

I had the same issue a few days ago and it resolved itself. Next morning I had the same issue except nothing would resolve it. Reseated the sim twice, reset network settings, did a soft and hard restart numerous times…it eventually came back about 8 hours later after about my 100th time putting it in and out of airplane mode. Hopefully they fix the bug soon.

Update on my iPhone 12 Pro Max.

After almost 2 weeks with TOTAL no services (can't read SIM card), suddenly 2 days ago, my service appeared back for some minutes. And went back to no service again.

Yesterday, i got signal for several hours before it disappeared again. Tried restart and other things but didn't work.

Today, my signal has appeared since morning. I can send SMS dan phone call. I didn't do any update, just reinserted SIM card and on/off airplane mode.

If this **** bug not coming back again, I have no reason to immediately update iOS 17.1 when it's launched. I'm sure there will be another bug.

I suggest you guys disable auto update software. Better to wait 1/2 months after the latest updated released.

I have faced the same issues since I bought the iPhone 14, I usually restore it from iTunes and the issue was getting resolved but it started happening frequently after every update. So I submitted my device in the service centre twice after arround 9th incident but no resolution, they just did restore and gave it back. Now I have submitted it again and service centre guys has raised escalation with Apple backend. It has been 6days but no resolution and no status whats happening. Regret buying Apple device.

Same exact issue happened to me. iPhone 13 Pro, the download automatically went through last night and so far I have been completely unable to connect to my data. Been having to use my school’s WiFi for everything but cannot text or call without it. Hoping it’s just a glitch, any solutions?

Any news guys?

I mean, I had this mobile error stuff with the iOS 16 and now again. Really ****** me off… I’ve tried everything… It’s the iOS version indeed. If this continues I’ll strongly consider moving on from apple, even though I have a Mac. The phones are expensive enough to give us this kind of error. Hopefully they fix this in the next patch or I’m done with iPhone!

iPhone 13 Pro. Los Angeles.

I updated on ios 17.0.1. First day, no data. Second day, seems to be working, but noticed some apps under cellular data was greyed out and could not use cellular for Safari, App Store.

Reset network settings, and no improvement.

Traveled for work to NY 3 days later. No data at all. Went to Verizon store in NYC, tried new eSIM, physical SIM, no solution. Verizon said take it to Apple Store.

Saw update for 17.0.2 in NYC. Updated, worked for a bit, then dropped off and data stopped working. After 6 days in NYC, the data came back, but still had App Store, Safari greyed out and could not toggle on. Took it to Apple store on my last day in NYC, after 4hrs, ran all diagnostics, phone had no issues. Apple recommended to factory hard reset and do not back up. Basically, start over.

Came back to LA and data worked. Saw 17.0.3, l updated hoping to resolve any/all issues, phone was same status. Cellular working, but some apps greyed out still. At least working somewhat.

Went to NYC again for business, lost all data for 7 days without any solution. No data, no calls, only working on Wifi. Restart button did not even work and had to let battery drain out to 0% to reset.

Came back to LA last night, and now no data still and only working on Wifi. Just did a factory reset and backed up from iCloud, still same issue.

This has been happening to me too over the last few days. I took it to T-mobile and they were unsure what was going on and swapped SIM cards. I'm hoping the issue goes away with the next update. Until then, I have to restart my phone a dozen or so times a day just to get service back.

I have had this issue on my 14 Pro Max, running on 17.0.3, where my network was completely knocked out for over two hours one day while I was on cellular. It was 'No Service', and multiple restarts, aeroplane mode switch, network settings reset DID NOT resolve this issue. I had two sim cards on my device coincidentally, one eSim one physical, and neither was working, so it was not an issue with the carrier settings as well. I tried enabling/disable both sim cards, nothing changed. It fixed itself two hours later.

Yesterday while I was on cellular once again, it was showing me bars on my cellular connection, but there were no calls coming in. Any body calling me was getting a 'Busy' message and then disconnected. Outgoing calls simply showed 'call failed'. This was fixed after an aeroplane mode switch.

Given the price of this device, and on a country like India where it cost me 1800$ for this device, this is absolutely unacceptable. I should not have to worry about why this is happening, software or what not. I shall wait for another update and monitor the connection in the time being. If it is not fixed, I'm going to have to switch to another manufacturer. I cannot accept the fact that a device which is shooting ProRes video cannot handle cellular connectivity.

im not really sure what you mean by channel

but i was contacted by Apple Care team ****

At day 1, i tried everything: reinsert; on/off airplane mode; restart network settings; use another sim card; restart phone many times. Nothing worked.

For almost 2 weeks, i just reinsert SIM card and on/off everyday. Suddenly my iPhone was back to normal again, the network was back

Nice workaround, but definitely there is a hardware issue which could result in something else later. Dumb Apple service center not able to understand the issue and not replacing the device, simply sending it back to me saying issue not reproducible next day when I update it then network service goes down. WORST SERVICE.

Apple is playing tactics .... that users to switch on new devices rather than using old one, which is truly unfair and these fancy phones are quite expensive. I got same issue with 12 pro max and tried all the options and now I am Planning to switch back to ios 16 to check if that's new update that causes all the mess. If 16 works perfectly then its problem with ios 17 version
