Cellular Issue Detected iPhone 13 Pro Max

Hi did you ever get this figured out? I’m here because of this exact issue. I’ve tried everything you’ve listed along with them removing my sim and creating an ESIM. It still doesn’t work. I’ve switched my phone number back to my old phone for phone calls but kept my current phone for on WiFi. Top right hand corner it’s a triangle with a ! In it, and says no service. And then in my settings it says cellular issue detected. This has been going on a month and my phone is completely unusable without WiFi.

also 13 pro max.

I’m desperate for answers at this point. Apple is no help and neither is US cellular.

I need help. My phone is also experiencing this issue. Thank you.

Same issue with 13 Pro Max after 17.2.1.. Google Fi is completely useless. my phone keeps draining battery with "No Cellular Coverage" and overheating.

SOS, one-bar, 5-bars, LTE, 5G. this loop keeps repeating itself.

I have reset network settings, i have done hard reset, and reconfigured. no dice.

I can' receive calls, or messages or use data.

Google Fi is clueless..

My I Phone 13 Pro Max is showing Cellular Issue after downloading 17.5 update. Funny how Apple was aware there were bugs in the update but sent it anyway. My wife owns a Samsung that works flawlessly. I guess when the consumer stops buying Apple then there eyes may be open

Same issues here for my iPhone 13 Pro. Data issues for the last 3 months, no event that caused the issues.

Googlefi couldn’t resolve it. Now moved to Verizon, and nothing, no change. It doesn’t work… Phone says 5g but no internet, it is a nightmare.

iPhone 13 Pro max) I feel everyone’s pain and frustration, let’s cut to the chase, for me I tried all the little steps… volume up and down, the airplane mode thingy etc,etc, etc, just back up your phone if you can, I had a 2nd pc I was able to use the encryption option this way you can save pretty much everything, use the iTunes software, after backing up your phone the iTunes program will download a whole new update(just in case you got a bad one the first time) when you encrypt make a password and please don’t forget it because when you restore your phone iTunes will ask you for that password that you made to put your backup back on your phone you just wiped, remember use the encryption option it’s save pretty much your whole phone info. Hope this helps, this was my last resort but it worked

I went to Apple care but for cellular issue they are charging $500, even though second hand pro max 13 costs less than $400, what a day time robbery.

That’s bs, instead of them just sharing the info they just wasted your time and my time reading their post

I have had the same issue with my iPhone 13 Pro Max - 'Cellular Issue Detected'. After this phone had been working fine for me here in Italy with my Italian Sim card which I have used for several years here, all cell service suddenly failed. I contacted Apple Support on my laptop and was told to do an update on my phone. Then I did a second consult with Apple Support (using an older iPhone which luckily I had here with me and used my Italian Sim card to receive the callback). That agent ran a diagnostic test on my 13 ProMax and quickly discovered a hardware issue. Because I have AppleCare+, he is arranging to send me a new phone as a replacement. So, in the end it appears that it was a hardware issue and not a software issue. I'm keeping my fingers crossed that the replacement phone will be the answer.

It sounds like you've already taken several important steps to address the cellular issue on your iPhone. Since you've worked with Apple support, updated your iOS, and obtained a new SIM card from your carrier, it's great to hear that your device's hardware and software seem to be in good shape.

My suggestion is to test the cellular issue in a different coverage area may help you identify the issue. Here's why this step can be beneficial and how to go about it:

Why Test in a Different Coverage Area:

1. Network Variability: Cellular signal strength can vary significantly depending on your location. By testing your iPhone in a different coverage area, you can determine if the issue is specific to your current location or if it persists across different areas.
2. Tower and Network Performance: Different areas might have different cell towers and network configurations. Testing in a different area can help you evaluate whether the issue is related to a particular tower or network infrastructure.

How to Test in a Different Coverage Area:

1. Choose a Different Location: Pick a location that is known to have good cellular coverage. This could be a different part of your city or a completely different city if possible.
2. Observe Call Reception: Once you're in the new location, monitor your iPhone for incoming calls. Pay attention to whether the issue persists or if you're able to receive calls consistently.
3. Compare Performance: If you notice that your iPhone receives calls without any issues in the new location, it could indicate that the problem is related to the cellular coverage in your original area.

Testing in a different coverage area can provide valuable insights into whether the issue is tied to your specific location or if it's a broader problem. If the problem does seem to be related to the coverage in your original area, your carrier might need to address network issues in that location.

Remember to make a note of your observations during this testing process, as it can be helpful information to share with your carrier or Apple support if further assistance is required.

Did you end up working it out?

Same is happening to me I just wonder is this another Apple trick to get you to by a new phone, I may after years of having Apple change now too Samsung.

Can you share with me what you did to fix the issue? I think it's a software issue also since this happened right after a iOS software update but apple claims the internals need to be replaced for $499.i have iPhone 13 pro Max also.
