iPhone 17 pro Cellular Connection Issue

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. 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: 10**********. 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?

I had issue with my new iPhone 17 Pro. It could not hold even one minute long conversation over FaceTime or WhatsApp or any data call. I did a lot of research, I went to the Apple Store and they ran the diagnostics. Everything comes fine. What finally did the trick was to delete all my eSIM and reinstall the eSIM by going to my T-Mobile store. The problem that is happening is the eSIM gets transferred to the new phone and that’s where there are some challenges. I guess the work around towards this is only to delete your eSIM and then reinstall mind you in the network store. They might just refresh the eSIM, but that does not work, you have to delete the eSIM and then reinstall the eSIM by the carrier.

I have the same connectivity issue since the IPhone 14pro. The phone keeps dtoping calls within a few seconds of the conversation! Several

times a days at any time I may have to call the person back 5-6-7 times to get a stable connection. Another issue is when I call out, it says “call failed” and I have to try 7-8 times to finally get it through. A third problem is people call me and the phone doesn’t ring, it goes straight to voicemail. I checked with my carrier ATT and they checked everything, there is no issue on their end. Also I have 2 other older iPhones on the same ATT service: those phones have no issues. So it is not a carrier issue. I brought the phone to the Apple Store to get it diagnosed a couple of times and no hardware issues.

the call drop is definitely an Apple software issue…

i was so frustrated because I use the phone almost exclusively for work.

thos last week I went to get an iPhone 17 pro, hoping to get rid of this problem.

but the 17pro has exactly the same problem!!! I give up.

if someone has a solution please post it here! I don’t know what else to do…

Came across this while researching calling issue on iPhone 17 pro for my boss. Apparently he can’t seem to make calls randomly. Incoming calls work fine but can’t seems to make out bound calls to centain mobile numbers. I’ll try to reconnect the device to the network or remove eSIM and install if still doesn’t work. The slow and connection issue can be related to private relay in iCloud. Try turning that off to see if it help. Spees test is serval time faster after turning that off. Turn of only if you need to mask your traffic.

I’m having the exact same issue and it’s incredibly frustrating. Ever since I upgraded to the iPhone 17 Pro Max (about a month ago), I’ve been experiencing constant signal drops. Both of my eSIMs — one from AT&T and one from Telcel (MX) — lose signal randomly, and the only way to get it back is by restarting the phone. It even disconnects from Wi-Fi at home.


I never had this problem with my iPhone 15 Pro Max. That phone was rock solid. This one? Not reliable at all.


I’ve taken it to the Apple Store three times. They ran diagnostics twice and found nothing. They just keep pointing me back to AT&T. AT&T, of course, says everything looks fine on their end and blames Apple. It’s a never-ending loop of finger-pointing.


On my third visit (today, November 5), I insisted they send the phone in for repair. They agreed — but only to replace the logic board, as if they still don’t believe there’s a real issue. I’ve had AppleCare for years, and yet they refuse to replace the phone outright.


I deeply regret upgrading. This phone has been nothing but problems, and no one wants to take responsibility. Something is clearly wrong — and I know I’m not the only one.

We have an issue with 17 pro max. Physical sim installed in the phone and every 1-2 days phone doesn't recognise the sim-card. Airplane mode and restarting the phone doesn't help. Only opening and closing the sim tray helps to comeback the network. We bought 2 same phones and the other one doesn't have the issue.

Very frustrated. Have many Apple devices. Using their products for more than 15 years. They got lots of money from me and my family. I think that's enough. Apple lost us and our money!

I’ve had the same issue but most of the time when I’m on a lengthy phone call more than 10 minutes. The call drops yesterday. I was on a call for about 32 minutes and it dropped three times. I had a 16 pro max before and never had an issue with long phone calls. Today I had to go to the store and used my Apple wallet and it failed to open up. I was told that it needs a cellular or Wi-Fi service for Apple wallet to work of course because it has to verify what you’re doing is approved.

I also noticed that Wi-Fi is a little bit slower than I expected. I’ve had more dropped calls with this phone than ever before with others.


17 Pro Max purchase on launch day.

I’ve had this problem on the last two phones I’ve had so that makes me think it is a Verizon issue. No one else on my plan is having any issues like this. I am currently on a 15 pro and was on a 13 pro prior to that. Verizon’s solution was to turn on Wi-Fi calling, but that didn’t change anything. I still lost signal and dropped calls even on Wi-Fi. About a month ago I turned off Wi-Fi calling and I haven’t had the issue since. Probably just coincidence though.

I’ve been having the same issue for a week now full bars/5G the it disappeared to NO SERVICE for about 2-3 seconds then I’m connected this can happen multiple times throughout the day sometimes very close together for some reason it only happens at work, contact apple support and my carrier multiple times like usual it’s no one’s fault! 😂 i have a week left before i can return it, never had this happened with my 15 pro max.

I am in the same boat. Went through my daily routine work > store > home with 0 drops in 3 years on my iPhone 14 Pro Max and I finally decided to upgrade and now I’m getting 10+ full data/voice drops per workday.


I’ve been going back and forth with Apple and the carrier and it’s just the Spider-Man meme where they’re all pointing at each other.


I guess I’m giving Apple until the end of the return window to fix this and if they don’t the phone is going back to them. Unbelievable that this shipped.
