I’ve recently updated my phone to the new iOS 17.0.3 version (I have and iPhone XR) and when I had opened and unlocked my phone it said “Cellular Issue Detected” and in the top left corner it say “No Signal”. How do I fix it? Would I call my cell phone provider to reinstate my service?

iPhone XR, iOS 17
I too have encountered this issue. I would highly recommend waiting for the next update before rushing to get a new phone or get it repaired. Why, you may ask?
Yesterday, I was on an extremely important business call. Randomly, my phone (13 pro) disconnected, giving me the call failed notification. Additionally, in settings, it said there was a “cellular issue detected”. I checked with my carrier, which was fine because my iPad (on the same plan) had four bars and 5g. I tried restarting my phone, but I encountered the issue again. I need reliable cellular access for my job, so I looked into why this was happening.
Today (at 1 am), I used the virtual diagnostic feature in settings to do a test over WiFi. All the while, I was texting with a virtual technician. Once the diagnostic completed, they responded:
“After I check with the report I see that there is an issue with the cellular hardware part. we will have to get this inspected with the help of the technician physically at the store.”
So, this evening, I went to the Apple Store to get it inspected. After looking at the test results for about 10 seconds, the technician said that there was an issue with the cellular module and therefore, my device would have to be replaced or repaired. I asked, how much will the repair cost (and I don’t have AppleCare because phone insurance is usually a scam if you have a decent case and don’t lose it). The technician responded 440 dollars.
I asked, how much does the part cost? He responded that Apple can’t replace just that part. Since they wire the cellular module with the “motherboard” (so the cpu and other central phone components), I would need to back up my phone (since the memory would also get replaced), and I’d have to send it in for the repair.
Let’s start things nicely. The technician was knowledgeable, friendly, and efficient. He did his job well and he even admitted that irreplaceability was a poor feature of iPhones. I applaud the honesty, even if it was defensive. However, if a technician can look at virtual test results for 10 seconds and know the exact problem, replacement procedure, and cost, THAT INFORMATION SHOULD BE SHARED WITH THE CUSTOMER OVER TEXT. I shouldn’t have had to reschedule a meeting and cancel a work dinner to make a one hour (each way) trip to the only available Apple Store in New York City, (Still ridiculous by the way) just for them to tell me something that could have been ascertained almost instantly by the diagnostic sensors inside my phone. It wasted two and a half hours of my time, (and it wasted the technician’s time.)
Here is the truly irksome part: this is a central component to apples business plan. Not only do they make their hardware difficult to replace, but apple designs their products in a way where any non-cosmetic repair (with the exception of the battery and camera) means giving your phone major corrective surgery and a heart transplant. Also, making a customer go to an Apple Store to have a technician “inspect your phone” when they clearly already knew the issue and corresponding replacement procedure (and cost) is nothing less than unremorseful deception. The fact that the technician didn’t even need to touch or see my phone means that Apple was simply trying to lure a customer into their store.
I will be waiting for the next software update and using my IPad as a hotspot until a software update (hopefully) fixes my phone, or until they come out with a phone that’s actually different than the last 3 models.

Remove and reinsert the SIM card.
If it doesn't help visit your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.
Ask also to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.
