We can clearly see that 136 people are facing the same problem plus a dozen more that didn't complaint yet but are about to. Apple need to come up with an update and get this sorted please ASAP.

I’m posting again for an update. Same issues as everyone else with an iPhone 15 Pro Max. Never had any other issues before it is not the carrier. I returned my brand new 15 pro max and went for a new 15 pro max.

I was hoping for problems to resolve, no bars at all in certain areas SOS is showing up even on the exchanged phone. This is frustrating since I use my phone mainly for work. I wonder what Apple is doing about this issue.

I was the happiest iPhone user with the iPhone 13 Promax. I skipped the upgrade to the 14promax and waited for the 15 promax. I have been using iPhones in this same house since the iPhone 7.


Now, I can’t take calls in my yard or house. I have to be on WiFi for calling. I am so dumb, I noticed this right away, I called in to apple. The rep told me there would be an update soon.


LOL, waited 3 weeks and called back. They said I needed to work with Verizon.


Now I have to force the phone to 4ltd or my phone gets hot and there is no way to take a call.


what is going on. Worst yet, my wife has her old Samsung which works perfectly in the house like my 13 promax did.


She thinks it is so funny. She says I have a very nice looking Flashlight.

I am having this same problem with my new iPhone 15 Pro Max. Using Vodafone in Uk in same exact location my android phone is getting strong 5G connection and working fine. however my iPhone keeps dropping internet connection. Even swapped the physical sim for eSim but the result is same.it works for like 30 mins then it stops working. i will give it another try tomorrow with support if they will not be able to solve it i am going to return the iPhone.

I am encountering a similar issue with my iPhone on the Jio Network. When I use the same SIM card in my Android phone, I consistently receive a full signal strength. However, my Apple 15 Pro MAX struggles with just one bar, and sometimes, it loses network connectivity altogether at my home.

Recently, I visited the Apple service center to address this problem. After conducting some diagnostics, they identified a reception issue and informed me that my iPhone needed to be sent to the Apple service center in Bangalore, India. During this process, they removed my $30 screen guard and $20 camera guard lens.

After two days, the Apple service center in Bangalore received my phone. However, shortly after, the service status changed to "Couldn't duplicate issue." They returned the iPhone to the authorized service center near me, and I strongly suspect that the underlying problem remains unresolved. Now, not only do I still face the reception issue, but I've also lost my $30 screen guard and $20 camera guard.

At this point, I am unwilling to collect my phone unless the service center rectifies the problem. It's disheartening to feel that a Chinese mobile phone costing just $100 outperforms my Apple iPhone. Purchasing this iPhone has become a regrettable decision in my life.

Hello Disgruntled Over Cell Service on Your $1k+ Purchase World,


Quick recap. I have a 15 Pro with remarkably horrible cellular reception (on Verizon and in a city) and was considering changing to a Max in the hopes of the larger antenna and more PCB copper would increase my changes of better cellular signal but this thread leads me to believe not. So I went into Apple Store today off the street b/c if you try to schedule a Genius Bar appt over anything cellular, their app just says talk to your carrier.


So I went in cold, and they were clearly VERY well coached to again try to push me to the Verizon store but I persisted. Waited an hour (whatever) and someone put my phone on a diag tool. Said there was one finding in that my 5G was set to Auto instead of persistently on so we changed that (didn’t help - phone signal is still worse than my 14 Pro in the same areas in that I just loose coverage where I could reliably talk before). He showed me a suite of tests on the modem that passed but there was one, that looked to be the MOST significant and shame on me for not screenshotting it, that would never complete so there was no conclusion. To me that is a huge red flag. It ended in them asking me to go to Verizon to get re-provisioned. I will do this, and I will report back. But WTF, I’ve owned literally every iPhone and never had this problem.

I have the same issues it is maddening. Phone is showing 5g with good reception but connection just stops working completely. I was in a strange city last werk and got exasperated. No google maps nothing. This needs to be foxed asap. I was just outside wanted to look something up, nope phone wasn’t having it (normally 5g connection is excellent here) I had to move back to my house for WiFi

You know, everyone who cared, warned me about the iPhone 15 and yet I was forced to upgrade since I was still using an iPhone X and it had run out of updates this year. And I’m pretty much regretting this decision BIG TIME thanks to the network issues.


I use 2 phones with 2 different network carriers and the Android shows full bars for both carriers, whereas the iPhone 15 which has an eSIM and a physical Sim never gets full network on either connection. The call drops are awfully irritating and it never reaches the full 5g speed either. This has been a disaster of a purchase and I’m so **** disappointed in Apple for making a Lemon.


I have no idea if this will ever get fixed since everything I’ve tried has failed, whereas the Android thunders on at full bars and full 5g speeds and virtually no call drops.


Is this the beginning of the end for Apple?

Hey there! I'm sorry to hear about your connectivity issues with the iPhone 15 Pro Max. Here are a few quick tips:

  1. Check Network Coverage: Make sure you're in an area with good signal coverage.
  2. Update Carrier Settings: Ensure your carrier settings are up to date in Settings > General > About.
  3. Toggle Airplane Mode: Turn it on for 10-15 seconds and then off to reset the connection.
  4. Software Updates: Check for and install any available software updates.
  5. Contact Carrier: If issues persist, reach out to your carrier for assistance.
  6. Apple Support: Consider contacting Apple Support or visiting an Apple Store for further help.

Hopefully, one of these steps resolves the problem. If not, reaching out to your carrier or Apple Support should provide additional support. Good luck!
