iOS 26 Cellular doesn't work after update

Yes…

It’s frustrating. My iPhone 16 pro max was working just fine but when I updated from iOS 18 to 26 and I’ve not been able to make calls, it keeps saying called failed.

I’ve restarted, I’ve reset network settings yet I can’t make calls.

Nothing literally works and I’m getting frustrated been 5 days my mother has health issues so she can’t really call me unless I have wifi and I’m getting worried when I leave the house cause what if something happens to her Apple needs to fix their update before someone gets hurt and they can’t call for help cause it will be in their hands

Not only has my iPhone had several problems since the iOS 26 update, but when I got on a support chat forum from VERIZON they referred me to a “tech pro” and a pop up window appeared that requested my credit info. The tech assured me that I would only be charge $1 and that would be refunded if the problem wasn’t solved. Well the problem was NOT solved and I was charged $46. Needless to say I’m very upset. My iPhone 15 doesn’t work so I cannot call my Bank or Verizon. I’m currently using my iPad to covey this message. PLEASE HELP. I’m 77 and house bound. So driving to the Apple Store several miles away in traffic is impossible. Apple has to do better. @Apple.com

I’ve been trying for 6 hours to solve in my iPhone 14 Pro Max this problem and tomorrow I’m traveling.

The SIM card doesn’t work it’s not even recognized after the upgrade! I downgraded to 18, and the card worked again, but then I didn’t have my files anymore! I’m extremely frustrated.

Probably because you jailbroke it with an unlicensed IPSW from a website? Downgrading is not supported.

iPhone 14 Portugal user here, I'm having the exact same issues. No amount of troubleshooting has solved this so far.

I've updated my other iPhone SE 2020 to iOS 26 and it works without any flaws. Go figure...

I am incredibly frustrated and hoping someone from the community or an Apple representative can help me resolve this. I bought a new iPhone 17 Pro on launch weekend and it has a significant, persistent issue.

Here’s a breakdown of what has happened so far:

• The Issue: The phone's cellular connection repeatedly fails. It goes from 5G to "no service," then to "SOS." This also causes repeated dropped calls. For context, the call dropped roughly 9 times during a senior support call. Here is a link to the screen recording: https://photos.app.goo.gl/czvc3MFguy6hAq3L7
• Apple Support: I've been in contact with Apple Support since day one. Their stance is that it's a carrier issue. I have a case number: 1027009xxxxx. The senior advisor on the phone confirmed the issue was clearly documented.
• Verizon Support: I have worked with Verizon's support team, and they have confirmed that they have done everything possible on their end. They believe it is a device hardware or software issue.
• The Replacement Catch-22: Apple has told me they will not send a replacement device without charging me for a new one. They also stated that if they can't replicate the issue, I will be charged, and my original phone won't be returned. This is an unacceptable policy.
• Left Without a Phone: To make matters worse, I've already sent my previous iPhone 12 Pro Max in for a trade-in credit, leaving me without a functioning device.

I am completely stuck. It's a brand new phone with a major issue, and neither Apple nor Verizon is taking ownership. I'm hoping someone here has experienced a similar situation or can offer some advice. Is there a way to escalate this with Apple to get a replacement without this unfair policy?

Apple doesn't participate here in this user-to-user forum. If you want help from them, you should continue to work with them. You won't get a different answer from Apple here.

The Replacement Catch-22:• Apple has told me they will not send a replacement device without charging me for a new one. They also stated that if they can't replicate the issue, I will be charged, and my original phone won't be returned. This is an unacceptable policy.

You could try contacting your local store to see what their stock situation is. In an ideal, not less than a week after launch world, you wouldn't go through the Genius Bar on this. You would return the phone and then buy a new one.

Left Without a Phone: To make matters worse, I've already sent my previous iPhone 12 Pro Max• in for a trade-in credit, leaving me without a functioning device.

Lesson for the future: Don't trade in the old phone until you're sure that everything is good with the new phone and that you like it.

Is there a way to escalate this with Apple to get a replacement without this unfair policy?

Only by continuing to work with Apple. But Apple can't give you what they don't have. If they don't have a phone in the store for you to buy, you'll need to order one.

IPhone 15 Pro (UK) user and since I updated to iOS 26 my data and WiFi have worked intermittently. They both show as connected but I can’t load anything like web pages or emails. I’ve reset my phone numerous times, reset network settings, removed and reinserted the sim and nothing is working. 😢 So frustrating! My WiFi is fine as it works with no problem on my iPad and MacBook.

What is happening if you dont change the PIN but enter it?

I have the same problem on IPhone 14 Pro Max. I updated to ios 26 and outgoing calls, mobile Internet and modem mode do not work. I tried everything I could, but nothing helps. T mobail operator
