iPhone 18 pro max cellular issues

Contact your carrier as they may have a Carrier Update for you or need to reprovision your SIM.

I went into an AT&T store and they said there was nothing they could do and that it had nothing to do with them or AT&T or my eSIM. They said dozens of people have come in since the phones were released with the same issues as me.. Also said I’d have to wait for for Apple to release a software update and hope that solves my issues.. I guess it’s just a waiting game for that unless you have any other suggestions?

Carriers are famous for the blame game. We got the 18 Pro and 18 Pro Max yesterday, and both are on AT&T and neither has any issue making or receiving calls. I would NOT wait for an update to come from Apple. This is most assuredly something AT&T needs to resolve for you. At the store level, you're not getting senior level technical support. You need to contact AT&T technical support and ask for a senior engineer.

Try switching to LTE.

Some users have reported switching Airport mode on for a minute or so resolved their issue.

Have you tried resetting your network settings? Fo you use a VPN?

Turn on wifi calling. Seemed to make the network turn back on for me for whatever reason.

I have the exact same issue only discovered yesterday. I got a hold of an AT&T Tech and he mentioned like in this community there have been a few reports of this and they are working to solve the problem. He tried a reset of my phone while I rebooted. He was actually able to call me back but couldn't hear me at first and then could and then the call dropped. I was able to make a Phone call after but then others failed. Like all of you I am seeing connectivity to the network with some spottiness and going to SOS, but for the most part seems connected with wi-fi, texting and the like working but Voice only working with Wifi Calling enabled. Still hard to tell if it is Network, Hardware or other issue. Ultimately I have not been able to get back in touch with AT&T.

This sounds like an issue for AppleCare or your phone service provider. Difficult to know whether its hardware or software.

Hi, what has your carrier’s support team said about the issue?

Alright I appreciate it. I kind of figured that what the store was trying to do. They didn’t seem very knowledgeable about anything regarding the issue to be honest. I’ll report back tomorrow after I call them

At the store, the person you may have spoken with could have sold shoes the week before. They are there to sell you a phone/accessories and/or cellular service. Elevate your issue with someone who has the ability to resolve it. Please come back after you've had some real technical support and let us know the outcome.

I have a new 18 pro max using Verizon and I’m having the same experience —> signal dropping completely MANY times per day. I’m ready to go back to my 14 pro max where this NEVER happened
