iPhone 15 Pro Max cellular service issues

Final confirmation that a re-provision of my eSIM by Verizon (via chat support on Verizon app right from the comfort of my home) did in fact provide a major enhancement to cellular calls in a rural environment where I was having catastrophic failure on the new iPhone 15 Pro. It doesn't sound like it's helping everyone but it did for me so I recommend at least doing that before trying to do a return.

Be it Software or Hardware. Apple Dont care to fix it.

Just visit the Apple Authorized service center and get it fixed. This can be done only while you have limited warranty. Else you wont be able to fix it, its a hardware issue, many iPhone 15 model phones have this issue.

Had zero issues up until a month ago. Same issues with phone calls and internet, regardless of area, started intermittently going silent for the person on the other end in phone calls. Reels/Shorts would take a couple seconds to load per video. Went to AT&T, they did a network reset. No fix. Couple days later, called Apple, they advised I enable WiFi calling and ensured I was up to date on software. Didn’t fix either. Went back to AT&T, they flashed the eSIM. Another software update has come out, I completed the update and not only is the phone and Internet issue is worse. I see this was posted in 2023, has anyone had luck actually resolving this?

I just got the 15 pro max switched to boost infinite and I’m sorry I did. I get perfect signal at my house but anywhere else it’s pretty wonky. My car says I’m constantly roaming. I was on the phone where I had 1 bar and my friend told me i kept cutting out. I had 12 pro max with att and regret getting rid of my phone and service. Worst of all I cannot get WiFi calling to work. I’ve had phone since Friday before Christmas and there is still no resolution to my problem. I’ve done everything they asked, spoke to them twice on phone and **** even went to the Apple Store on Christmas Eve. Thinking of returning this phone and getting an older model getting back on ATT

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.

With my 14 I had 5 bars of 5g. With my new iPhone max I have 2.

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.

So disappointing… just bought my IPhone 15 Pro Max and it gets way worse cellular service, wifi reception than my 11… should I return this thing? I honestly can’t believe it. Wow. Smh.

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 started by getting re-provisioned with Verizon after reading this and it did not do any good. It doesn't seem to be even a signal issue. I am getting 50% signal, which normally would be fine. The issue is that the phone doesn't even work with 50% signal. UGGHHH

Thank you to everyone posting here as I thought it was just me ! ….. I’ve just paid outright to purchase a 15 Pro and whereas I’d get say strong 4G at home I’m now only getting very weak 3G making it virtually unusable.

let’s hope this thread of posts can somehow prompt a positive response somehow with a resolution from Apple in next software upgrade maybe?

if not I’ll have to return my 15 Pro.

Count me in! - I’m gutted to find my 15 pro not connecting to networks anywhere near as good as my much older SE that I had previously- this is a shambolic situation and surely there has to be a solution from Apple technicians at some point? 🙏🏿

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?

I am also having the same problem brought the 15 pro max on Saturday, having constant connection problems with and without WiFi, with SOS coming up and having to reboot my phone at least once a day! Very frustrating! I am also having problems with receiving and making phone calls and my phone stops my Apple Music and won’t replay and just freezes!

what have people done with the phones after this problem? Have you taken the phones back to get a new phone or just waiting for an update?
